The paper is dedicated to the investigation of adhesion strength in film coatings. The goal of the work is a qualitative estimate of the strength of film antifriction coatings applied on friction units of machines. The topicality is grounded by the fact that the friction decrease on surfaces in units ensures the increase of life, power effectiveness and reliability of machinery. Most of the works are dedicated to the study of manufacturing films, their phase composition, structure, stress-strain properties, whereas in the material offered the adhesion properties of film antifriction coating are emphasized, which is a sufficient novelty. During the investigations of the adhesion strength of antifriction film coatings there was used a method of a normal detachment. To carry out comparative tests there were prepared four groups of different antifriction coatings. For each coating under testing there were prepared five samples which were loaded with the smooth increase of a breaking tension. Therefore there are obtained experimental dependences of normal stresses (σ) upon relative elongation (ε), which allow using values obtained for surfaces coated with antifriction film coatings with different areas. Upon completion of coating tests both parts of the samples tested were subjected to visual analysis. In the course of the analysis a character of destruction was defined. As a result of the theoretical and experimental investigations carried out there were drawn conclusions describing a qualitative and quantitative estimate of the adhesion strength of antifriction film coating.

A paper is dedicated to the investigation of inertia impact upon coating adherence with the outer surface of revolution solids during coating application. The work purpose is a qualitative and qualitative assessment of factors of antifriction coating application affecting the parts of friction units of machines and units. The relevance is substantiated with that the strength increase of coating applied ensures life, reliability and power effectiveness of machines and mechanisms. The work novelty consists in the application of fundamental dependences and laws to actual manufacturing operations. Adhesion is a basic parameter charactering quality of the coating applied. Adhesion, in its turn, is characterized with adhesion strength and porosity of the coating applied. The material presented shows the impact of inertia acting upon particles of the coating applied at their falling on the outer surface of rotation. There are defined theoretical dependences describing the process mentioned. The analysis of these dependences shows that inertia can carry out both the positive and negative action during the application of antifriction coatings. To confirm the theoretical results obtained there were carried out experimental investigations. In the experiment took part some sets of samples upon which PRNH17SR4 antifriction coating was applied. Coating application was carried out with the aid of the Iskra-1 burner with the further fusing. For the qualitative and quantitative strength assessment of adhesion of the coating applied there was used a method for a shear test. The samples prepared were pressed through a matrix on the GMS-50 universal rupture-test machine. As a result of tests carried out there are obtained dependences characterizing adhesion of antifriction coating applied. The dependences obtained show efficient factors impacting the adhesion strength of coatings. By the results of theoretical and experimental investigations there are formulated qualitative and quantitative assessments of factors influencing the process of antifriction coating application on parts.

This work contributes to the development and characterization of the corrosion resistance and antifriction properties of high performance polyurethane (PU)/graphene (Gr) composite coating. In this study, PU composite coatings containing 0, 2, 4 and 8 wt.% of Gr were prepared and evaluated using various corrosion and mechanical tests, namely electrochemical impedance spectroscopy, salt spray tests, cross-cut tape tests and dynamic mechanical analysis. Antifriction properties of the coatings were evaluated using a tribometer with a ball-on-disc mode at room temperature. The corrosion resistance and adhesion property of the PU coatings were found to be enhanced by adding 4 and 8 wt.% of Gr. The coefficient of friction revealed that the antifriction properties of the PU/Gr composite coatings were 61% lower than those of the conventional coating when the Gr content was increased to 8 wt.%.

In the paper, the technology of obtaining antifriction coatings by the method of finishing antifriction-free abrasive treatment with the implementation of the wear-free effect is proposed. (Research purpose) The research purpose is in developing an effective technology for obtaining copper coatings on the surface of steel parts of the shaft type to reduce the wear rate in the conditions of oil starvation of machine parts. (Materials and methods) During the study, a laboratory facility for the synthesis of antifriction coatings on the surface of steel parts by the method of finishing antifriction-free abrasive treatment has been developed. Brass of the LS-59-1 brand was used as a material for applying a copper antifriction coating. In order to activate the surface of the part and the surface of the filler material, a technological medium based on a ten percent solution of hydrochloric acid and glycerol was used. Authors determined the composition of the technological environment empirically. The obtained laboratory samples were subjected to tribological studies in comparison with standard antifriction alloys. X-ray diffraction studies were performed to determine the phase composition. (Results and discussion) As a result of X-ray diffraction studies of laboratory samples, the presence of iron and copper components in the synthesized coating was studied. The content of oxides on the surface of the coating is insignificant, the internal structure is dense with no visible porosity. The coating consists of 95 percent copper, the synthesis process takes place without oxidation, which gives the coating a high adhesive and cohesive strength. The coating thickness is uniform and varies within 3-5 micrometers. (Conclusions) Comparative tribological studies have shown high resistance to wear and to the setting of the contact surfaces under conditions of oil starvation. The coefficient of friction is stable and low and is in the range of 0.08-0.15. The developed technology makes it possible to increase the wear resistance of steel parts of the shaft type in the shortest possible time and with minimal material costs and can be successfully implemented in the conditions of repair enterprises.

Post-installed anchors for civil construction are elements that ensure the integrity of building structures even under the most severe static, seismic and shock loadings. Despite the high popularity of this technology in construction sites all over the world, the current state of knowledge is limited and there is still a great potential for significant improvements. Specifically, expansion anchors’ mechanism relies purely on friction, therefore being able to manipulate and optimize their tribological behavior is key to meet strict safety regulations and develop outperforming and outlasting design solutions. This research project, conducted at Hilti Corporation in Schaan (Liechtenstein), presents an investigation of several antifriction coating solutions. Laboratory-scale tests have been performed to quantify the different coefficient of friction while, with full-scale standardized tests (anchor set in concrete), it has been possible to evaluate the overall mechanical performances of the specimens. Afterwards, the obtained data have been analyzed with numerical software and the samples have been further investigated with optical microscopy. The outcome of this thesis work is crucial for the development of the next generation of expansion fasteners and gives additional insights for a deeper understanding in the tribology of functional coatings.
Eftermonterade fästankare i byggnader säkerställer byggnadsstrukturernas integritet, även under de mest allvarliga statiska, seismiska och chockbelastningar. Trots stor användning och popularitet  på byggarbetsplatser över hela världen är det nuvarande kunskapsläget av denna teknik begränsat och det finns en stor potential för betydande förbättringar. Specifikt bygger expansionsankringsmekanismen på ren friktion. Därför är möjligheten att manipulera och optimera fästankarnas tribologiska beteende nyckeln till att uppfylla strikta säkerhetsbestämmelser och kunna utveckla bättre prestanda och designlösningar. Detta forskningsprojekt har utförts på Hilti Corporation i Schaan (Liechtenstein) och presenterar en undersökning av flera antifriktionsbeläggningslösningar. Laboratorieprov har utförts för att kvantifiera olika friktionskoefficienter, och efter fullskaliga standardiserade tester (med fästankare i betong) har det varit möjligt att utvärdera de övergripande mekaniska prestationerna av dessa. Erhållna data har analyserats numerisk och proverna har undersökts ytterligare med optisk mikroskopi. Resultatet av detta examensarbete är viktigt för utvecklingen av nästa generation expansionsfästen och ger även ytterligare insikt och en djupare förståelse av tribologin av funktionella beläggningar.

A new approach to oil lubricity improving is considered. It bases on changes in molecular structural ordering of adsorbed oil boundary layers governed by a highly oriented solid substrate. Among diamond-like coatings with varying structure there are some ones (with monocrystalline or polycrystalline structures) having orientation effect on molecular ordering of lube oils what leads to decrease in friction coefficient. It is shown that orientating and adsorption effects of carbon coatings can be intensified by additional active centers creation on their surfaces, particularly by nitrogen atoms doping. The tribotests had shown better antifriction properties of nitrogen doped coatings at various contact loads both under dry friction and under friction in lube oils as compared with that of amorphous carbon coating and uncoated steel.

Roller ball bearings are the most common and one of the most important components in rotating machinery. Bearings, in general produce vibrations which can be harvested to produce energy and analysis of these vibrations can also be used to determine the condition of ball bearing. In this paper we discuss how to use the bearings for energy harvesting and conditioning monitoring in machines. A sleeve, padded with piezoelectric material, is designed to solve the dual purpose. Piezo electric materials have the ability to generate an electric field or electric potential in response to applied mechanical strain. Tests are conducted on the good and defective bearings to study the effectiveness of the sleeve. Phase fluctuation based processors are found to be effective in ball bearing condition monitoring. For condition monitoring the signature responses for a given time period are studied. At a constant speed of increase in load leads to an increase in voltage generated. For a single non-coated piezo film, voltage varies from 383 mV at 80 lbf to 683 mV at 320 lbf at 40Hz. With the increased stacking of non-coated piezo films at 320 lbf, voltage generated shows an increase of 23 %. Nano-coating mixture (Ferrofluid and Zinc oxide nanoparticles) causes an additional piezoelectric effect on the surface of piezo film as ZnO acts as an additional source of electrons, due to its ability to emit charges at room temperature. The single piezo film configuration at 320 lbf generates a voltage of 663 mV while the voltage increases 2.1 times for a single nano-coated piezo film. Introduction of defects causes increases in the contact stress at the asperities leading to an increase in the vibrations and forces. Also, an increase in vibration and force, leads to an increase in the voltage generated. For a single piezo film configuration, in a normal bearing, the voltage generated is 663 mV while a defective bearing gives a voltage of 698 mV.

The basics of antifriction coatings is to lower the frictional response of a surface. The coated material should either lower the interfacial shearing or increase stiffness of the surface. The latter should be reached by using carbon nano-fillers embedded in a polymer matrix. We choose PMMA as a matrix. The objective of this study is to gain knowledge on the influence of carbon nano-fillers on the surface response of PMMA nano-composites.

Abstract This paper provides results from experimental studies with regard to novel, thermally sprayed coatings for tribological applications, which consist of mechanical mixtures of cast iron powders (2.16% by weight C and 5.18% by weight Si) and solid lubricant (calcium fluoride or iron oxide) produced in an amount of 10 to 20% by volume. It was established that a basic phase of initial cast iron powder and detonation coatings is gamma-Fe and it is alpha-Fe in plasma coatings. Oxide inclusions which are products of cast iron oxidation are observed in coatings structure. Metallographic investigations showed an uniform distribution of solid lubricant inclusions in a metallic-matrix of coatings. Tribotechnical tests of coatings containing 20 vol. % calcium fluoride carried out in conditions of room temperature indicated that the best antifriction properties were obtained for coatings with calcium fluoride additions which were sprayed by supersonic air-gas plasma method. Paper includes a German-language abstract.
