Abstract

The purpose of the research is to investigate the destruction processes in coating materials during friction. These researches have been conducted on composite electrolytic coatings with titanium carbide and silicon carbide powders used as fillers. The assessment of surface layer destruction has been performed using the methods of theoretical and experimental research results analysis as part of an energy model based on wear particles formation in surface areas of a friction pair. Besides, the dependence of wear particle size on the mechanical properties of material has been determined. The analysis shows that material is destructed faster for carrying particles of larger sizes during friction. This means that materials with a higher hardness have a smaller size of carrying particle and materials with higher strength have a bigger size of carrying particles
