Abstract:

The paper presents the results of studies aimed at justifying and developing the ways and means of cylindrical parts made of hardenable alloys surface hardening by heating of the electric arc between the inert electrode and the element. The shapes of electrode sharpening and the position of the electrode relative to the element are substantiated. The sequence of surface hardening operations is revealed and the critical rate of cooling is determined and its value is proved with numerical experiments. It was necessary to develop a program for calculating temperature fields in details, with a difference-differential scheme obtained from a combination of explicit and implicit schemes being developed for the first time. A number of investigations were conducted to determine the mechanical properties, the residual stresses, the fatigue resistance, the hardness and the microstructure of hardened layers. As a result, the surface hardening technology is recommended for reconditioning and manufacturing cylindrical machine elements.

Abstract:

The performance of the machines part reinforcement using surface plastic deformation shall be considered as formation of the whole complex of surface parameters and quality and their impact on the operational properties of these parts. The main surface quality parameters, affecting the performance of machine parts are geometric (microgeometry, wavelength, roughness, shape of inequalities, the size of the supporting surface, the direction of the traces of processing); physical parameters (structure, degree and slander depth, residual stresses in the surface layer). In the machine building, many methods of superficial plastic deformation are used for part reinforcement; these methods essentially differ in the scheme of impact of the surface deforming part to be treated. After analyzing the results obtained by scientists, involved in research on surface plastic deformation of surface layers and surfaces of parts, it was found that after hardening, practically all structural changes contribute to reinforcement of the surface layer material and increase the plastic deformation resistance. Increasing the density of dislocations and the separation of carbides, which block the shear slides and create obstacles to the movement of dislocations. Due to these changes, resistance to formation and spread of fatigue cracks have increased. The treatment depth, magnitude of residual stresses and increase in hardness depends on the original structure and chemical composition of the material. Reinforcement regimes have significant effects on the wear resistance. Use of diamond smoothing, vibration processing, combined methods (surface plastic deformation in combination with other reinforcement methods, as well as the use of a combined tool) opens up new possibilities for increasing the quality characteristics of the surface and the surface layer of parts, and accordingly, increasing their operational properties with all the diversity and complexity of used processes. Based on the results of the studies, practical recommendations on the application of methods of hardening by surface plastic deformation of machine parts and a methodology for designing technological processes for their manufacture considering manufacturing capabilities are proposed.

Abstract:

Abstract The development of modern technologies for the restoration and hardening of agricultural machine parts require the development of a mathematical apparatus that simulates the involved processes. For this purpose, the models should take into account the technological features of the process of hardening and restoration of machine parts, including: cleaning; determination of geometric indicators; surface preparation; choice of technology; subsequent machining of the resulting surface; surface quality control. One of the priority directions in the development of technologies for the restoration and hardening of parts is the formation of coatings on machine parts using powder materials applied by the gas-thermal method. One of the most important conditions for obtaining high-quality coatings is temperature control on the surface of the part. In this regard, it is of scientific interest to study the effect of the distance from the surface of the part to the flame nozzle when applying self-fluxing powder on the time-average temperature at the point of coating, the maximum temperature on the back side of the part, and the total power transferred to the part by the gas burner. This paper presents a mathematical model for determining the above-mentioned influence, and also presents the results obtained using a computer program. The novelty of the model is the ability to use it to study temperature values for complex curved-bent machine parts (crankshafts and camshafts of agricultural machines). To check the reliability of the dependences obtained, experiments were carried out and the convergence with theoretical developments was confirmed.

Abstract:

Choosing effective methods and devices for surface hardening of wood-cutting tools is problematic due to the variety of their designs and operating conditions. In this regard, the development of such devices becomes an urgent task. According to the literature, one of the effective methods for increasing the service life of machine parts and tools is electrospark hardening or electrospark alloying. Industrial electrospark installations such as “EFI” (electrophysical measurements) and “Elitron” with manual vibrators are used for electrospark hardening. However, using manual vibrators significantly increases the labour intensity and hardening time. Moreover, the surface quality after hardening with manual vibrators is often unsatisfactory. Various mechanized installations have been developed in order to reduce the labour intensity of electrospark hardening. Nevertheless, these installations are designed to harden specific parts and do not allow hardening tools of various designs, including woodcutting tools. The surface quality after hardening in mechanized installations does not always satisfy the customer. Further surface plastic deformation treatments, such as rolling and unrolling with rollers and balls, as well as diamond burnishing, are often used to improve the surface quality after electrospark hardening. The surface quality after additional processing by these methods boosts, although the labour intensity and cost of the hardening process increase. To increase the wear resistance of machine parts and tools, it is reasonable to reduce the height parameters of roughness, increase microhardness, and form the residual compressive stresses, which is ensured by the methods of surface plastic deformation. In this regard, it becomes necessary to use electrospark hardening simultaneously with surface plastic deformation. The work presents the design and features of using the device for hardening. The device was used to strengthen the thicknesser machine knives, which made it possible to almost double their durability. Applying this device, in comparison with using the electrospark hardening with a manual vibrator, reduces the roughness of the hardened surface and improves the surface quality of the processed workpieces. The modes of hardening have been installed, making it possible to effectively harden wood-cutting tools. For citation: Buglaev A.M. Device for Wood-Cutting Tool Hardening.

Abstract:

The increased wear resistance of machine parts continues to be one of the most urgent problems of modern machine engineering. Despite the intensive development of different ways of protective hardening treatment, the technologies based on thermochemical methods are quite popular and widely used to improve the performance characteristics of parts. Nitriding of the surface layer of parts as a way of improving their reliability has a considerable history of development and improvement and continues to develop relying on scientific advances in the field of high energies. However, tightened operating conditions of modern machines and equipment require creating new nitriding technologies that can provide a complex of properties of parts surface layer and therefore specified performance characteristics. This article is devoted to the research and development of a new technology of nitriding parts made of alloyed steels. The specific feature of the proposed nitriding technology consists in creating the conditions for thermochemical treatments of parts allowing forming a nitrided layer which is homogeneous in structure and composition.

The thesis for the scientific degree of doctor of technical sciences, specialty 05.02.08 – technology of mechanical engineering (13 – mechanical engineering). – National Technical University "Kharkiv Polytechnic Institute", Kharkiv, 2019. In the thesis a set of studies was aimed at solving an important scientific and technical problem in the field of engineering technology: the development of innovative and short-term technologies of machine parts surface hardening with controlled composition powder mixtures to ensure the performance properties of products at a high level with a significant reduction in the cost of their production. Mathematical models and nomograms of existing technologies of steels surface hardening were created to determine the specific conditions of ChTT (temperature and duration) based on a given depth of the diffusion layer or the surface hardness of steels, which significantly affects the efficiency of the strengthening processes. The general methodological approach of management of technological processes of details surface hardening by powder mixes of the controlled structure at saturation of surface layers with nitrogen, carbon and boron on the basis of use of innovative technologies and the system analysis at the minimum expenses was developed that allowed to increase operational properties of products at considerable reduction of ChTT duration. ChTT was designed the complex, which significantly reduces the fragility of boriding layers due to a more gradual decrease in hardness from surface to core products from steels to improve the operational properties of the goods and service life of machine parts and tools. It was created a mathematical model of the temperature distribution in the depth of the diffusion layer to determine the nature of the dependencies and obtain data on the temperature distribution in the depth of the product under different processing conditions. It was improved boriding pastes technology of titanium alloys through the use of nanodispersed environment, thereby reducing the boriding process 2-3 times and to shorten the manufacturing process of components by combining two operations: boriding and titanium alloy hardening. The solutions of boundary value diffusion problems by the boundary element method were proposed, which allowed to create a mathematical model of the distribution of boron concentration over the thickness of the hardened titanium alloy. The processes of heating by high-frequency currents and due to the preliminary laser treatment of parts were intensified, which allowed to obtain high performance properties of the surface layers with a significant reduction in the duration of treatments. A comparative analysis of the influence of existing and developed hardening treatments on the change in the depth of the layer, the surface hardness and wear resistance of the surface layer of steel 38Ch2MoAl was done. It was established that the developed complex hardening treatment based on the process of diffusion saturation with boron can provide wear resistance of the surface layers at a high level with abrasive wear.

A presente pesquisa teve como objetivo, investigar o efeito do teor de carbono e do tamanho do abrasivo na resistência ao desgaste e no fenômeno de encruamento superficial de quatro aços Hadfield. Para esse estudo, foi montado, o equipamento pino contra disco, e, como abrasivo utilizou-se lixas de ferro, com o tamanho médio entre 36 µm e 93 µm. Para o alcance do objetivo proposto foram delimitados materiais e métodos, a saber: (a) montagem do abrasômetro pino-disco a partir de um dispositivo desativado disponibilizado pelo LFS-USP; (b) confrontar resultados experimentais – dois materiais (Aço 1045 e alumínio 6351) foram submetidos a ensaios realizados na UFPE e USP para fins de estudos comparativos; (c) avaliação da influência de parâmetros do ensaio – três abrasivos com diferentes tamanhos de partículas e diferentes cargas foram submetidos e avaliados mediante o desgaste abrasivo; (d) avaliação do comportamento de diferentes composições do aço Hadfield perante ensaios de abrasividade – aços contendo quatro diferentes teores de carbono foram submetidos a ensaios com lixas #220 e #320; (e) análise das superfícies desgastadas – após os ensaios dos materiais, as superfícies foram realizadas análises por microscópio eletrônico de varredura (MEV) das superfícies desgastadas. Os resultados obtidos com o equipamento na metodologia empregada tiveram uma boa reprodutibilidade. Foram observadas diferenças nos resultados entre os equipamentos da UFPE e da USP. Quanto a este tópico, o desgaste abrasivo do aço Hadfield foi influenciado pelo teor de carbono apresentando uma relação em que maiores teores demonstraram menor efeito de desgaste, diferentes tamanhos de abrasivo ocasionam um efeito de encruamento significativo, onde se observou o ganho de dureza em aços com menores teores de carbono. Contudo, foi apresentada uma oscilação do efeito no abrasivo #320. As micrografias revelaram microssulcos e microcortes provenientes do ensaio e não foram observadas diferenças nas marcas de desgaste quando utilizados tamanhos diferentes de partícula abrasiva. Ao final, chegou-se a conclusão de que os resultados obtidos demonstram que o teor de carbono influência na resistência ao desgaste do aço e consequentemente no encruamento superficial do aço. Observa-se também a influência do tamanho do abrasivo e carga aplicada o ensaio.
This research aimed to investigate the effect of the carbon content and the size of the abrasive in the wear resistance and surface hardening phenomenon four Hadfield steel. For this study , has been assembled , the disc against pin device and abrasive was used iron sandpapers, with average size between 36 m and 93 micrometers. To achieve the proposed objectives were defined materials and methods, namely: (a) mounting the pindisk abrasômetro from a disabled device provided by the LFS-USP; (b) comparing experimental results - two materials (1045 steel and aluminum 6351) were submitted to tests performed at university and USP for purposes of comparative studies; (c) evaluation of the influence of the test parameters - Three abrasive particles with different sizes and different loads were submitted and evaluated by the abrasive wear; (d) assessment of the behavior of different steel compositions Hadfield before abrasiveness tests - steels containing four different carbon contents were subjected to tests with sandpaper # 220 and # 320; (e) analysis of the worn surfaces - after the tests of materials different analyzes were performed by scanning electron microscope (SEM) of worn surfaces. The results obtained with the equipment in the methodology employed had good reproducibility. There were differences in results between the equipment and the UFPE USP. On this topic, the abrasive wear Hadfield steel was influenced by carbon having a relationship in which higher levels showed less wear effect, different abrasive sizes cause a significant strain hardening effect, which was observed gain hardness steel with lower carbon content. However, an oscillation of the abrasive effect on the # 320 was presented. The micrographs revealed microssulcos and microcuts from test and differences were observed in wear marks when using different sizes of abrasive particle. In the end, came to the conclusion that the results show that the influence of carbon content in the wear resistance of steel and consequently the surface of the steel hardening. It is also observed the influence of abrasive size and load applied to the test.

Abstract:

AbstractMechanical properties inherently possess uncertainties. Among these properties, fatigue behavior data generally shows significant scatter which introduces a challenge in the safe design of dynamically loaded components. These uncertainties in fatigue behavior are mainly results of factors related to surface state including: Roughness, tensile residual stresses, scratches and notches at surface. Therefore, controlling these parameters allows one to increase fatigue strength and reduce scatter and uncertainties in fatigue behavior. Mechanical surface treatments are applied on parts to increase fatigue strength via introducing compressive residual stresses and work-hardening at surface. Two of the most common among these treatments are shot peening and deep rolling. Shot peening has found many applications in industry because of its flexibility. However, it introduces irregularities at the surface and may increase roughness which causes uncertainties in the fatigue behavior data; especially for low-medium strength materials. Unlike shot peening, deep rolling reduces surface roughness. Therefore, it has the capability to reduce uncertainty in the fatigue behavior. To this date, rolling direction of deep rolling was selected as tangential direction to turning direction for axisymmetric parts. Nonetheless, the authors believe that the rolling direction has an apparent effect on the fatigue behavior. In this study, longitudinal direction was also applied for deep rolling operation and the results of these two direction applications on the EN-AW-6082 aluminum alloy were investigated. It was shown that, longitudinal rolling had yielded less scatter and uncertainty in the fatigue behavior than the tangential rolling together with the higher fatigue strength.

Abstract:

316L is a type of austenitic stainless steel that offers a good combination of mechanical properties, corrosion resistance, and biocompatibility. In some industrial applications, it is necessary to proceed to finish treatments to extend the lifetime of the mechanical parts. In the present chapter, ball burnishing treatment is applied to improve the surface integrity of 316L since the performance behavior of parts is directly dependant on the surface properties of the used material. Both surface topography and surface microhardness of 316L after subjection to ball burnishing are studied. The number of burnishing passes is varied by up to five to investigate its effect on the results. Optical profilometer and atomic force microscopy (AFM) were used to analyze the surface roughness and surface topography texture while measurements of microhardness Vickers were proceeded to investigate the changes in surface hardening.

Abstract:

Laser Metal Deposition (LMD), an additive manufacturing process (also known as 3-D printing) and a non-traditional fabrication process used for improving the surface integrity of components is presented in this chapter. In LMD, parts are manufactured directly from the 3-D Computer-Aided Design (CAD) model data. Complex parts can be produced in a single step, which is impossible with the traditional manufacturing methods such as casting, cutting, and turning operations. The major steps required in the production of parts using the laser metal deposition process are highlighted. The flexibility offered by the LMD technique makes it an important surface engineering technique. Composite parts or parts whose surfaces are made of composite materials can also be produced in a single step because two or more dissimilar materials can be handled simultaneously in the LMD process to produce parts. This is because the building of parts in LMD is achieved by the LMD machine following the detail described by the CAD model of the part being made. The processing parameters affecting the properties of laser metal deposited parts are described in detail. This chapter establishes the ability of the LMD in the production of complex and one of its kind parts, its ability to improve surface properties, repair high-valued parts, and reduce the buy-to-fly ratio in the production of aerospace parts. It also highlights the use of non-traditional finishing techniques on laser deposited parts to further improve the surface integrity of components. The chapter is concluded by presenting a laser metal deposited Ti6Al4V/TiC composite. The laser metal deposited Ti6Al4V/TiC composite was characterized through the microstructure, microhardness, and wear resistance, and it was found that the resulting deposits were fully dense and of improved surface properties when compared to the parent materials.

Abstract:

Recently, with the high performance and efficiency of machine, there have been required the multi-functions in various machine parts, such as the heat resistance, the abrasion resistance and the stress resistance as well as the strength. Fatigue crack growth tests were carried out to investigate the fatigue characteristics of high carbon steel (SM53C) experienced by high-frequency induction treatment. The influence of high-frequency induction treatment on fatigue limit was experimentally examined with the special focus on the variation of surface microstructure and the fatigue crack initiation and propagation through fractography. Also, the shape of hardening depth, hardened structure, hardness, and fatigue-fracture characteristics of SM53C composed by carbon steel are also investigated.

Abstract:

Machine parts operating under contact cyclic loads are subject to a destruction risk in the event of their working surface pitting (destruction). To increase the service life of such parts, various finishing and hardening technologies are used. In the absence of standard methods used to assess the durability of parts operating under contact endurance conditions, they have should be developed in relation to a specific case. The fractal geometry methods' usage in analyzing the surface layer state of parts operating under contact endurance conditions is complicated due to high equipment cost and fine and coarse noise high risk, which negatively affects the quality of generated images. The aim of the work is to develop a simple and accessible method for evaluating the results of contact endurance tests, based on the analysis of the investigated surface images. The developed patented technique consists of several stages. At the first stage, high-resolution photographing of the surface under investigation is performed using a microscope, providing magnification of no more than 1 ? 50. At the second stage, the obtained image is analyzed in the cad editor, where the number and area of the investigated defects are determined. At the third stage, wear result numerical assessment is carried out according to the proposed algorithm.

Abstract:

Cold rotary forging is an innovative incremental metal forming process whose main characteristic is that the workpiece is only partially in contact with a conical tool, reducing therefore the required forging loads. However, in spite of many benefits of such a process, wide industrial implementation of rotary forging is not possible without proper understanding of material behaviour. In the present work, the capability of rotary forging process was explored for the manufacturing of flared cylindrical parts by cold forming. Another main aim was to assess the cold formability of high-strength materials for aerospace applications (martensitic stainless steels) under incremental processes. In order to understand the impact of rotary forging on the final properties of formed components, microstructural and mechanical analysis were performed. Microstructural and hardness analysis were conducted on both axial and transverse sections along the cold formed flange in order to study the grain flow orientation and strain distribution. In a similar fashion, mechanical test specimens were machined from different positions and orientations along the rotary forged component. Further analysis was performed on the components in the as-treated condition in order to understand the response of cold-worked Jethete M152 components to subsequent heat treatments. Microstructural and hardness analysis clearly reveals a strong grain reorientation and strain localization around “pickup“ defects (material attached to the upper tool) observed on the flange top surface, close to the flange edge. These results suggest that an excessive deformation is localized during the early stages of the flange formation. Another characteristic feature found in the rotary forged parts is the presence of a buckling phenomenon which appears in later stages of the rotary forging process. Strain hardening along with the increasing flange length requires higher levels of forging loads to keep forming the flange. This results into a significant accumulation of compressive stresses in the transition region between the flange and the straight region. Gradually the resultant compressive force exceeds the critical buckling load, leading to the occurrence of the buckling phenomenon. This latter issue determines the limit of the cold flaring process. This can help to determine the maximum length of the flange part, achievable in this process, which is of great importance for the design of these manufacturing technologies. From the mechanical testing results, large differences were found as a function of both position and orientation (axial, transverse) throughout the rotary forged components (anisotropic properties). Concerning the impact of heat treatments on cold-worked components, no differences were found in the as-treated condition, in terms of microstructural and mechanical properties between regions with a large difference in strain distribution. These results denote the normalizing effect of conventional hardening treatments on cold-worked Jethete M152 components, restoring the homogenous and isotropic properties across the whole component.

Abstract:

The austenitic stainless steels have excellent mechanical and chemical characteristics and these materials are widely used for the main structural components in the nuclear power plants. A part of structural components using these materials is considered to have strain-history by machining, welding and etc in the process of manufacturing and these parts would be hardened because these materials have a remarkable work-hardening property. On the other hand, conventional studies for the fatigue strength used to be investigated by the results of fatigue tests applying normal specimens without the effect of hardening by pre-strain. This paper describes the effect of large pre-strain on very high cycle fatigue strength of the materials in consideration for the evaluation of strength of actual structures in the nuclear power plants. In order to achieve this purpose, the fatigue tests were carried out with strain hardened specimens. The material served in this study was type SUS316NG. Up to ±20% pre-strain was introduced to the round bar shaped materials by tension and compression load test, and the materials were mechanically machined to the hourglass shaped smooth specimens. On the other hand, the pre-strain of some specimens were introduced after machining so as to study the influence of roughness of the surface of the specimens for the fatigue property. Fatigue tests were conducted by ultrasonic and rotating-bending fatigue test machines and conditions were decided by preliminary examinations to control temperature elevation of the specimen during the fatigue test. The S-N curves obtained from fatigue tests show that increase in magnitude of the pre-strain cause increase in the fatigue strength of the material and this relationship is independent of type of the pre-strains of tension and compression. Though all specimens were fractured by the surface initiated fatigue crack, only one specimen was fractured by the internal crack and so-called “fish-eye” was observed on the fracture surface. However, the internal fracture of the SUS316NG does not cause sudden drop of the fatigue strength. Also, the Vickers hardness tests were carried out to discuss the relationship between fatigue strength and hardness of the pre-strained materials. It is found that the increase in fatigue limit of the pre-strained materials strongly depend on the hardness derived from the indentation size equals to the scale of stage I fatigue crack.

Abstract:

Nickel-based alloys (Ni-based alloys) are used on a large scale in military, aerospace, missile and defense applications with the aim of improving performance, life, and fuel efficiency. Grinding is extensively used for final finishing of these components. Due to their specific material properties, such as work-hardening and low thermal conductivity, the workpieces made of Ni-based alloys are difficult to grind. The difficulty consists in finding the combination of dressing and grinding parameters that generate the prescribed dimensions, finish, and surface integrity of the finished part with high productivity. Increasing productivity is generally associated with increasing the material removal rate. This, in turn, can create detrimental effects on the ground parts such as micro-cracks, high residual stresses, white layers, and thermal damage. This paper presents a novel methodology for determining an optimal combination of dressing and grinding parameters with respect to maximizing the material removal rate, while taking into account a number of process constraints including: grinding force, power, surface roughness, wheel wear, and surface integrity. According to this methodology, predictive models for grinding behavior are determined using a reduced number of experiments based on an in-process, fast sensor data acquisition system. The models are used as inputs for the multiple criterion optimization program based on a genetic algorithm approach. A CNC surface grinding machine was instrumented to allow process monitoring and data collection. The model building and the optimization methodology have been validated using specimens made of Ni-based alloys. The workpiece materials and the range of the grinding parameters were selected according to applications from aerospace industry. The results support the use of adopted methodology for finding the optimal combination of dressing and grinding parameters.

Abstract:

Abstract In a rollover accident, both rear axles of a Sports Utility Vehicle (SUV) were fractured adjacent to the wheel-mounting flange. The purpose of this paper is to describe the methodology and experimental techniques used in determining whether one or both axles failed prior to the accident, and thus contributing to the accident, or whether both axles failed as a result of the rollover and the ensuing impact with the highway. Scanning Electron Microscopy (SEM) technique was used to obtain detailed characteristics of the fracture surface on both axles. Through-thickness hardness profile of the axles was determined using incremental micro-hardness measurements in order to assess the depth of case hardening in both axles. Impact, tensile and fatigue specimens were machined from the remaining parts of the failed axles and were tested to destruction using standard impact (Izod), tensile and fatigue tests. The fracture surface characteristics of the test specimens were compared to those of the failed axles in order to isolate the mode of failure. Based on the results of the above tests, the history of the repair work performed on the rear wheel bearings and the physical evidence of various marks and damages remaining on the vehicle’s body, it was determined that one of the rear axles failed prior to the rollover, while the other occurred as a result of the rollover and ensuing impact with the highway.
