Abstract
This paper discussed the results of tribological investigations of composite coatings on a copper-graphite powder base with up to 25 mass % of non-metallic antifrictional filler. The influence of the composition and structure of the thin coatings on their frictional behavior has been studied. The coating composition has been optimized in relation to its antifrictional properties and the adhesion of solid lubricant particles to the metallic matrix. Tribological tests can be used to define the optimum proportions of components of the composite, to provide a low friction coefficient and minimum wear rate of coatings. Analyses of the composite microstructure and wear debris show that there are competing influences of changes in lubricity due to the antifrictional filler and in the adhesion of filler particles to the metallic matrix.
