Abstract:
The calf serum solution was defined as the international standard lubricant for wear characterization of artificial hip joints. It is, however, known that its composition varies according to age, manufacturing processes or production areas of bovine cattle, and that the difference in composition has large effect on the wear characterization. It was difficult to compare the results obtained by different laboratories. Therefore, it is desirable to develop an artificial lubricant whose composition can be always set to a specified value as an alternative to bovine serum. In the present study, the effect of each major constituent in bovine serum on wear property was studied by hip simulator. As a result, transparent and stable lubricant solutions were prepared. It showed quite similar wear property to bovine serum by controlling the composition. These results serve as a guide to propose the new lubricant suitable for the wear characterization of hip joint.

Abstract:
Wear of the articulation partners in artificial joints for hip or knee is known to influence the in vivo survival rate of the implants. Wear amount can be strongly increased if third body wear occurs in the joint gap. Alumina ceramic is noted for a good wear resistance even under these worst case conditions. We tested the wear behaviour of the new dispersion ceramics ZTA (Zirconia Toughened Alumina) and ATZ (Alumina Toughened Zirconia) in comparison to alumina for the couplings ceramic on PE and ceramic on ceramic in a hip joint simulator in presence of third body particles.

Abstract:
Abstract As with all artificial joints, wear debris is of particular concern due to its effect on both implant life and the in vivo biological reactions that can occur. The purpose of the research is to study debris characterization of PCU. Wear particle is produced from testing the PCU material using a pin on disc wear tester within 50000 cycles. This study showed that the PCU wear debris gotten from the simulator had various different shapes, including laminar and spherical types. The morphology of worn surface and wear debris analysis showed that wear mechanism of PCU were fatigue wear. Thus we conclude that PCU is expected to be a lifetime implantation of artificial joint.

Abstract:
Wear of polyethylene and the resulting wear debris-induced osteolysis remains a major cause of long-term failure in artificial hip joints. There is interest in understanding engineering and clinical conditions that influence wear rates. Fluoroscopic studies have shown separation of the head and the cup during the swing phase of walking due to joint laxity. In ceramic-on-ceramic hips, joint laxity and microseparation, which leads to contact of the head on the superior rim of the cup, has led to localized damage and increased wear in vivo and in vitro. The aim of this study was to investigate the influence of joint laxity and microseparation on the wear of ceramic on polyethylene artificial hip joints in an in vitro simulator. Microseparation during the swing phase of the walking cycle produced contact of the ceramic head on the rim of the polyethylene acetabular cup that deformed the softer polyethylene cup. No damage to the alumina ceramic femoral head was found. Under standard simulator conditions the volume change of the moderately crosslinked polyethylene cups was 25.6 ± 5.3 mm3/million cycles and this reduced to 5.6 ± 4.2 mm3/million cycles under microseparation conditions. Testing under microseparation conditions caused the rim of the polyethylene cup to deform locally, possibly due to creep, and the volume change of the polyethylene cup when the head relocated was substantially reduced, possibly due to improved lubrication. Joint laxity may be caused by poor soft tissue tension or migration and subsidence of components. In ceramic-on-polyethylene acetabular cups wear was decreased with a small degree of joint laxity, while in contrast in hard-on-hard alumina bearings, microseparation accelerated wear. These findings may have significant implications for the choice of fixation systems to be used for different types of bearing couples.

Abstract:
Wear is a common cause for aseptic loosening in artificial joints. The purpose of this study was to develop an automated diagnostical method for identification of the number and size distribution of wear debris. For this purpose, metal debris samples were extracted from a hip simulator and then analyzed by the electrospray method combined with a differential mobility analyzer, allowing particle detection ranging from several nanometers up to 1 µm. Wear particles were identified with a characteristic peak at 15 nm. The electrospray setup was successfully used and validated for the first time to characterize wear debris from simulated total joint replacement. The advantages of this diagnostic method are its time- and financial efficiency and its suitability for testing of different materials.

Abstract:
Alumina ceramic heads have been previously shown to reduce polyethylene wear in comparison to cobalt chrome (CoCr) heads in artificial hip joints. However, there are concerns about the brittle nature of ceramics. It is therefore of interest to investigate ceramic-like coatings on metallic heads. The aim of this study was to compare the friction and wear of ultra-high molecular weight polyethylene (UHMWPE) against alumina ceramic, CoCr, and surface-engineered ceramic-like coatings in a friction simulator and a hip joint simulator. All femoral heads tested were 28 mm diameter and included: Biolox™ Forte alumina, CoCr, arc evaporative physical vapour deposition (AEPVD) chromium nitride (CrN) coated CoCr, plasma-assisted chemical vapour deposition (PACVD) amorphous diamond-like carbon (aDLC) coated CoCr, sputter CrN coated CoCr, reactive gas controlled arc (RGCA) AEPVD titanium nitride (TiN) coated CoCr, and Graphit-iC™ coated CoCr. These were articulated against UHMWPE acetabular cups in a friction simulator and a hip joint simulator. Alumina and CoCr gave the lowest wear volumes whereas the sputter coated CrN gave the highest. Alumina also had the lowest friction factor. There was an association between surface parameters and wear. This study indicates that surface topography of surface-engineered femoral heads is more important than friction and wettability in controlling UHMWPE wear.

Abstract:
It is well known, that wear of the articulation partners of hip joint prostheses affect the long-term durability of the implants in vivo. The wear is dramatically increased if particles in the artificial joint gap act as third body. Those particles can also occur after a fracture of a ceramic component. Until now there are some different guidelines which coupling (metal-polyethylene, ceramic-polyethylene, ceramic-ceramic) should be used for revision. We tested and compared the wear behaviour of a ceramic-PE-pairing and a ceramic-ceramic-pairing under third body wear conditions with alumina-particles in a hip joint simulator.

Abstract:
As wear is inevitable with artificial joint replacement, it has to be minimized to avoid possible aseptic loosening following osteolysis due to particle-initiated foreign body reaction. Co-Cr-Mo-C alloys have a long history with only minimum wear when articulating with themselves. This investigation shows that the choice of the alloy has an effect on the wear rate of this articulation couple. Tribological studies in a screening device, a pendulum apparatus and a hip joint simulator showed a marked influence of the environment as well as the diameter of the implants with metal-on-metal articulation. A wear-resistant combination with low friction characteristics has been developed by using a wrought Co-Cr-Mo-C alloy and reducing the implant diameter to 28 mm. Clinical wear rates are comparable with laboratory data and demonstrate the potential of the metal-on-metal articulation to solve the problem of wear-induced osteolysis of hip joint endoprostheses.

Abstract:
Low-temperature-degradation-free (LTD-free) zirconia-toughened alumina (ZTA) has been developed as an alternative to alumina and zirconia. It has been reported that ZTA has more beneficial mechanical characteristics than alumina, because of the stress-induced transformation and the spontaneous transformation of the zirconia phase that occurs for some ZTA in a hydrothermal environment. To achieve high-reliability artificial-joint prostheses, it is necessary to improve both the mechanical characteristics and phase stability of the joint material simultaneously. Thus, in this study, we evaluate the wear characteristics and corrosion resistance of LTD-free ZTA using a hip wear simulator, so as to confirm the long-term stability and reliability of this material in clinical use. The ZTA with advantageous mechanical characteristics used in this study has extremely high wear and corrosion resistance. Therefore, this ZTA could be quite useful as a bearing material in artificial joints for longer-term clinical use. It is also confirmed that the newly developed LTD-free ZTA is extremely stable under sliding conditions. Thus, it can be expected that the initial superior surface characteristics will be maintained through long-term clinical use.

In order to investigate the biotribology behavior of a novel artificial joint pair composed of a carbon/carbon composite femoral head and an ultra-high molecular weight polyethylene (UHMWPE) acetabular cup, a hip joint simulator was employed to predict the clinical wear behavior with a constant load and a lubricant of newborn calf serum. The worn surface and the wear particles generated were analyzed by scanning electron microscopy and laser particle size analyzer. The results showed that the worn surface of UHMWPE had a ripple-like morphology with plentiful furrows. The wear particles generated had various morphologies with a size concentrated at about 15 μm.

ENGLISH ABSTRACT: This thesis is concerned with the continued development of the Stellenbosch University joint-type knee wear simulator. Initially, information regarding simulators from the literature and commercial entities was collected to provide a knowledge base for current and future work. To further the design of the simulator itself, electronic hardware and software subsystems was developed and evaluated during experimental testing procedures. National Instruments’ cDAQ 9174 data acquisition unit was deemed inadequate for real-time inputoutput control, though proved sufficient for signal capturing purposes in conjunction with LabView software. Furthermore, the various servo-pneumatic sub-circuits’ individual ability to conform to the ISO 14243 series standards’ protocol led to the estimation of measurable performance criteria and the application to a single circuit for illustration. The anterior/posterior actuation circuit in question demonstrated adequate performance for the cases where the piston’s rod was respectively fixed and free to move. In-silico modelling and identification of the relevant servo-pneumatic components then commenced, with the valve and cylinder chamber models yielding adequate estimates of the recorded data. The identified quasi-static friction model proved sensitive to transient effects present within the system, resulting in performance deterioration of the integrated model. Sufficiently accounting for these effects would result in the emergence of the sub-circuit’s model as an invaluable tool in terms of control system development, prediction of the simulator’s behaviour and subsequent design recommendations. Future work therefore concerns improvement, identification and integration of the various sub-circuit models to fully exploit the aforementioned advantages.
AFRIKAANSE OPSOMMING: Hierdie tesis handel oor die voortgesette ontwikkeling van Universiteit Stellenbosch se gewrigstipe knie-afslytingsimulator. Aanvanklik is inligting versamel vanaf literatuur en kommersiële entiteite om sodoende ’n kennisbasis te verskaf vir huidige en toekomstige werk. Elektroniese hardeware en sagteware stelsels is ontwerp en geëvalueer tydens toetsprosedures om die ontwerp van die simuleerder self te verbeter. National Instruments se cDAQ 9174 dataversamelaarseenheid word onvoldoende geag vir intydse inset-uitset beheer, maar wel vir dataversamelingsdoeleindes tesame met LabView sagteware. Die nodigheid om die verskeie servo-pneumatiese sub-stroombane se individuele vermoë om aan te pas by die ISO 14243-reeks se protokol-standaarde te ondersoek, het gelei tot die beraming van meetbare werkverrigtingskriteria en die toepassing daarvan ter illustrasie. Die anterior/posterior stroombaan het voldoende werksverrigting getoon vir studies waar die suier se stang onderskeidelik vas en los was. In-silico modellering en die identifisering van servo-pneumatiese komponente het hierna begin. Die klep en silinderkamer modelle het voldoende skattings gelewer van die gemete data. Die geïdentifiseerde kwasistatiese wrywingsmodel het sensitiwiteit getoon teenoor die oorgangseffekte teenwoordig in die stelsel wat gelei het tot verminderde werksverrigting van die geïntegreerde model. Deur rekening te hou met sulke effekte kan die sub-stelsel se model waardevol wees sover dit beheerstelsel ontwikkeling aangaan, sowel as die voorspelling van die simuleerder se optrede en die daaropvolgende ontwerpsvoorstelle. Toekomstige navorsing kan fokus op die verbetering, identifikasie en integrasie van die verskeie sub-stroombaan modelle om die voorafgenoemde potensiaal ten volle ontgin.

Abstract:
Metal on metal articulations used in hip joint replacement were demonstratedth rough the 1960's and 70's to perform adequately and comparably to metal on plastic articulations but their use then fell into decline as orthopaedic surgeons preferred metal on polyethylene articulations. However, one of the main causes of failure of prosthetic hip joints was then discovered to be aseptic loosening due to particle induced osteolysis, such particles arising from wear of the prosthetic components, and in particular from polyethylene bearing surfaces. Through the late 1980's and the 1990's the concept of metal on metal bearings has re-emerged as one potential solution to the clinical problems associated with polyethylene particle induced osteolysis. In this thesis both theoretical analysis and practical testing using a 12 station MMED hip joint simulator were employed to investigate how metal on metal articulations may be optimized so as to reducet he amount of wear debris generatedth rough their use. Hence, such articulations should function effectively within the environment of a human hip joint when they form part of a total hip replacement design. To this end the effect of diametral clearance, head size, and material composition were both tested and analyzed. Finally a modular clinical design of hip joint replacemenwt as tested to assess its performance. Wear was found to be strongly related to bearing clearance in practical tests as predicted by the theory. A lower limit of clearance existed due to deviations from perfect form which were unavoidable with current manufacturing technology. A band of clearance was defined for 22, 28, and 35mm diameter bearings within which reduced wear was exhibited. Steady state wear rates, following the initial bedding in period, were generally equal regardless of total wear volume. High carbon against high carbon content cobalt chromium articulations did not produce the lowest wear contrary to previous studies in the literature. The mean hardness of, and hardness difference between, bearing surfaces influenced the wear performance of metal on metal articulations. It was possible to design a clinical metal on metal bearing having modular femoral (head and stem) and acetabular (insert and shell) components with optimized metal on metal articulation. This metal on metal device has been introduced into clinical use throughout the world.

Abstract:
The tribology of a wide range of designs of compliant layer acetabular cups has been evaluated using a simulator. The simulator applied a dynamic load of 2 kN and a sinusoidal motion of ±25 , and measured the frictional resistance directly. In general the friction developed in these joints was extremely low, with friction factors typically below 0.01. When the experimental results were compared with theoretical estimates of friction a poor correlation was found. Further analysis suggested that the design of compliant layer acetabular cups was insensitive to many of the parameters suggested by theory. In particular, the radial clearance and femoral head size were not found to be critical. In addition, methods were proposed and their effectiveness demonstrated to measure friction at the on-set of motion (start-up friction), and the steady state friction in realistic compliant layer knees. The adhesion between compliant layers and a rigid backing have been investigated, with the aim of developing a good bond between them. The peel test was used to demonstrate an excellent diffusion bond between a low modulus medical grade polyurethane, and a similar high modulus grade of polyurethane. The processing conditions used to manufacture the test piece were optimised to maximise the bond strength. The bond was found to be stable after immersion in Ringers solution at 37 C for 52 weeks, and after acetabular cups were subjected to 14 million 4 kN loading cycles. A six station knee wear simulator was designed and commissioned. The simulator applied a dynamic load and an anterior-posterior translation individually to each station, as well as a flexion-extension motion common to all six stations. The simulator was computer controlled entirely using servo hydraulics. Wear rates were obtained from tests lasting up to 8 million cycles conducted on UHMWPE joints.

In aging society, the artificial knee replacement become increasingly common, however wear of the artificial knee components will happen after long-term use, which thus gives rise to other problems, or even failure. This research mainly aims at analyzing the wear of these artificial components and evaluating the cryogenic treatment for wear resistance. Wear analysis in vivo and in vitro measurements. The in vivo measurement could be carried out by analyzing the X-ray photos, the amount of wear could be estimated by the characteristic values of X-ray photos of a tibia insert; the in-vitro measurement can be accomplished by AMTI Force5 wear testing machine in accordance with ISO 14243 standard. Then the cryogenic treatment was utilized to compare the wear performance of components with and without this treatment. The analysis of in-vivo measurement shows that it has some difficulties to find the characteristic values of X-ray photos as to estimate the amount of in-vivo wear due to the complex shape a tibia insert, the in-vitro testing results indicate that AMTI Force5 wear tester in accordance with ISO 14243 standard is more practical and widely accepted by customers, which is useful for in-vitro wear measurement. In addition, the results show that the cryogenic treatment can significantly enhance the wear resistance.

Abstract:
Over the years, different lubricants have been used to operate hip simulators. The current applicable ISO standard (ISO 14242-1:2002) recommends the use of 25% calf serum diluted with deionised water. The standard further recommends that the fluid be changed and the acetabular cup be weighed every 500 000 cycles. This procedure results in a loss of both the third body wear particles and the wear pattern. The purpose of this study was to develop a synthetic lubricant that would map the viscosity and lubricity properties of joint fluid (“synovial fluid”) over the whole duration of a simulator test, which is typically five million cycles. The first objective of this study was to find the effect of temperature increase on the viscous and lubricative properties of joint fluid retrieved from both primary and revision patients prior to surgery. The lubricity tests were done on a Linear-Oscillation Test Machine (SRV machine). Three test temperatures were used namely 38ºC, 50ºC and 60ºC. The load at failure and the average coefficient of friction were parameters measured during these tests. A decrease in the load at failure was found for an increase in test temperature, while the coefficient of friction stayed relatively stable. The viscosity tests were done using a Brookfield Viscometer. The three test temperatures mentioned above, were copied. The joint fluid tested showed pseudoplastic flow behaviour. An increase in the viscosity as a function of test temperature increase and a magnitude of shear rate was observed. The second objective of this study was to develop a synthetic lubricant that had the same average properties than that found for the retrieved joint fluid. A mixture of three different chemicals, namely Poloxamer 188, Xanthan Gum and Lube Boosterâ II was used to map the viscous and lubricative properties of the joint fluid. A comparative test using the synthetic lubricant and bovine serum was performed in a custom-built simulator. Wear debris was sampled at 500 000 cycle intervals up to 4 500 000 cycles. During these intervals the bovine serum stations were drained and washed with deionised water, but not stripped and weighed as specified in the ISO standard. This was done intentionally to preserve the wear pattern during the entire test. The synthetic lubricant stations were not stripped or drained during these intervals. This ensured that the wear pattern was maintained and that the effect of accumulative wear could be investigated throughout the duration of the test. The wear debris from the test was then compared to wear debris retrieved from scar tissue of revision patients. The wear debris that was found in the scar tissue retrieved from patients was similar in shape and size to that which was found in the simulator using bovine serum and the synthetic lubricant. It can thus be concluded that an acceptable lubricant had been developed to replace the current test medium in the simulators.

Abstract:
AbstractOrthopaedic and dental implant treatments have allowed to enhance the quality of life of millions of patients. Total hip/knee arthroplasty is a surgical replacement of the hip/knee joint with an artificial prosthesis. The aim of joint replacement surgery is to relieve pain improve function, often for sufferers of osteoarthritis, which affects around a third of people aged over fifty. Nowadays, total hip and knee replacement (THR) surgeries are considered routine procedures with generally excellent outcomes. Given the increasing life expectancy of the world population, however, many patients will require revision or removal of the artificial joint during their lifetime. The most common cause of failure of hip and knee replacements is mechanical instability secondary to wear of the articulating components. Thus, tribological and biomechanical aspects of joint arthroplasty are of specific interest in addressing the needs of younger, more active patients. The most significant improvements in the longevity of artificial joints have been achieved through the introduction of more wear resistant bearing surfaces. These innovations, however, brought about new tribocorrosion phenomena, such as fretting corrosion at the modular junctions of hip implants. Stiffness mismatch between the prosthesis components, non-physiological stress transfer and uneven implant-bone stress distribution are all involved in premature failure of hip arthroplasty. The development of more durable hip and knee prostheses requires a comprehensive understanding of biomechanics and tribocorrosion of implant materials. Some of these insights can also be applied to the design and development of dental implants.

Abstract:
Artificial joints are the most successful long-term treatment for arthritis. Artificial joints have improved the quality of life for millions of patients; however, one of their major limitations is that failure of the device requires a surgical revision. A wear simulator is a valuable tool for testing the long term wear behavior of artificial joints and developing optimal designs before they are implanted in clinical settings. One of the issues related to artificial joint wear is potential temperature elevations caused by friction between articulating components, which affects not only the lubricant in-between, but also induces heat conduction through the components of the simulator. It has been suggested that the temperature elevations, if sufficient, may roughen the component interface, therefore leading to increases in wear. 1–2

Abstract:
Local reactions to wear debris generated by hip and knee replacement devices have been shown to lead to failure of some devices via osteolysis and component loosening. This has not been shown to be a clinical issue with the most widely used spinal artificial disc prostheses, but the because of the proximity of these devices to sensitive neural structures in vivo, the issue deserves examination. The purpose of the present study was to investigate the wear characteristics of a lumbar artificial disc under simulated motion and loading conditions. In vitro testing using a modern joint simulator with loads and motions representative of possible lumbar spine motions show a relatively low polyethylene wear rate out to 10 million cycles with a dependence of resulting wear on input load and motion parameters.

Abstract:
A new structure of artificial joints with bionic joint capsule was proposed and designed to overcome the feedback of current prostheses that omitted many functions of lubricant and joint capsule. The new structure was composed of three components: therapeutic lubricant, artificial joints and artificial joint capsule. The lubricant sealed by capsule not only can reduce the wear of artificial joints but also can prohibit the wear particles leaking to the body liquid. So the unwilling reactions between the wear particles and liquid may be avoided completely. Meanwhile, a three-dimensional (3-D) finite element analysis (FEA) model was created for the bionic artificial joints with joint capsule. The effects of capsule thickness and the flexion angels on the stress values and distributions were discussed in detail.

Abstract:
Total knee replacements (TKR) have been used for the past four decades [1]. Conventional knee (tibiofemoral) wear simulators have been used to facilitate improvements in the design of TKRs [2]. This, along with surgical improvements has caused the success rate of implants to increase to 97% over a period of ten years [3, 4, and 5]. However the decision to resurface the patella still remains an issue [6, 7]. Research has been performed into the in vitro wear simulation of the patella femoral joint (PFJ) [8, 9, and 10] but to date none of these simulations have employed all six degrees of freedom (DOF).

Abstract:
Improvements in surgical procedures, installation techniques and properties of materials have resulted in a remarkable reduction in the failure of artificial hip joints (AHJ) due to infection. However, the durability of these replacements is greatly limited by premature osteolysis and eventual joint loosening, caused by macrophage activity in response to the release of submicron particles of ultra-high molecular weight polyethylene (UHMWPE) cup material [1–4]. The wear debris is mainly due to wear between the bearing surfaces, and these wear rates are known to be accelerated by the third body action of polymethylmethacrylate (PMMA) bone cement particles and metallic fragments of the femoral head material scattered within the synovial fluid lubricant [5]. This study is focused on development of a model that simulates the motion of UHMWPE particles in the synovial fluid between the AHJ bearing surfaces during articulation.

Abstract:
The wear prediction of artificial joints is a very difficult task due to several factors. First, one could notice a large domain of joint loading due to the wide spectrum of common activities. Secondary, to account for the evolution of contact conditions due to wearing could imply a high level of nonlinearity and time-consuming algorithms in order to solve. The authors tried to overcome all these difficulties by using a complex predictive model that combines statistical evaluation, nonlinear mechanical analyses of load transfer by the contact interface and tribological estimations of the wear characteristics. After a theoretical description of the predictive model, one could notice an application for an artificial Total Hip Prosthesis — a frictional CoCr alloy on ultra high molecular weight polyethylene (UHMWPE) couple. Several loading regimes are considered as characteristic for the common activity of the patient (normal walking, stair ascending and descending). For every regime a dynamic Finite Element simulation of the frictional contact was performed establishing the contact traces and the contact pressure distribution. Those characteristics combined with the frequencies of the activities considered are input data for computing a special point function which distribution over the contact surface could be a good measure of the wearing regime, qualitatively as quantitatively.

Abstract:
Electrical submersible pump (ESP) is one of the most widely used artificial lift methods in the petroleum industry. It is crucial to study the wear in ESP stages with sand production, which can severely reduce pump performance and life span. Usually, experiments and simulation studies were conducted for simple flow geometry such as direct impingement and pipe elbow. Various erosion equations and models were developed for different material and affecting factors. However, the predictions of these erosion models for complex flow geometry need to be evaluated in order to make a proper selection. This study will compare the wear patterns and erosion rates of six different erosion models in three ESPs by using commercial Computational Fluid Dynamics (CFD) software ANSYS Fluent. The results will offer engineers a brief guidance of erosion model selection for complicated flow domain. In this paper, stages of three ESPs, DN1750, TE2700 and Flex31, are modeled. For each pump, the flow domain of two stages are selected and high-quality structured meshes, comprising around 1.2 to 1.8 million hexahedral grids per stage, are generated by ICEM or Turbogrid. Six erosion models, Ahlert (1994), Haugen (1995), Zhang (2007), Oka (2007), Mansouri (2014) and DNV (2015), are simulated under pump best efficiency point. Among six selected erosion models, Ahlert (1994) gives a much higher wear rate than others, while DNV predicts lowest, Besides, the impact angle functions show that all models, except Haugen (1995), assume steel to be a ductile material. Furthermore, the erosion pattern, location, and distribution of all three pumps are different, which indicates different solid particle handling capabilities and failure reasons of radial type and mixed type ESPs.

Abstract:
Diamond-like carbon (DLC) is a class of materials with outstanding mechanical, tribological and biological properties. From in-vitro experiments, it is known that by incorporating other elements into the DLC film, the ratios of the different proteins adsorbed on the surface can be changed. These proteins will then subsequently control cell attachment, cell proliferation and cell differentiation. In a total hip joint replacement, the metallic femoral head, which slides against a polyethylene pan, causes polymeric wear debris. These wear particles may then trigger inflammatory reactions, resulting in osteolysis (bone resorption) and subsequent implant loosening. DLC has proven its outstanding tribological properties in many technical applications, mainly due to the build up of a transfer layer on the counterpart. DLC coated load bearing implants sliding against ultra high molecular weight polyethylene (UHMWPE) have been investigated. The different in-vitro experiments apparently showed contradicting results, mainly due to the different experimental setups and especially the different liquids used as lubricants. The synovial fluid present in a biological joint, contains large organic molecules which function as a boundary lubricants. Phospholipids, proteoglycans or proteins can be chemisorbed on the joint surfaces and trap water molecules, resulting in water acting as a viscose lubricant. When a DLC coated femoral head is tested against a polyethylene pan in a hip joint simulator, using synovial fluid as a lubricant, the build up of a transfer layer, protecting the softer counterpart (i.e. the polymer) does not seem to take place and the UHMWPE counterpart still shows wear. However, when DLC slides against DLC in medical applications, the build up of a transfer layer may not be a critical issue or is not drastically altered by the presence of proteins, and very low wear rates could be obtained in different in-vitro tests. Additionally, DLC coatings have an excellent haemocompatibility, which is expressed in a decreased thrombus formation. When exposed to blood, an increased ratio of albumin to fibrinogen adsorption, as well as decreased blood platelet activation is observed on coated surfaces. A few DLC coated cardiovascular implants such as artificial heart valves, blood pumps and stents are already commercially available. When coating a metal with DLC, good adhesion is obtained due to the about one nanometer thick metal-carbide reaction layer at the DLC/substrate interface. Upon implantation, it has to be guaranteed that this reaction layer is also chemically long-term stable under in-vivo conditions.

Abstract:
Some open questions raised by the reaction of tissue on particles require the knowledge of the acting wear mechanisms. These have to be clarified within the macro-, micro-, and nanoscale. Thus, this contribution focuses on the wear mechanisms of hard-hard artificial hip joints which have been verified to act both in clinical application and both during laboratory simulation. Some aspects of novel developments will be discussed on the basis of these findings.
