Abstract

The dislocation substructures of electroexplosive composite coatings deposited onto copper and modified by a high-intensity electron beam are analyzed. It is revealed that a highly defective multiphase structure is formed in the surface layer of the coatings and that molybdenum and tungsten nanoinclusions are generated in Mo-Cu and W-Cu coatings. Particles of carbides (Mo<inf>2</inf>C and WC) and titanium boride (Ti<inf>2</inf>B<inf>5</inf>) are observed in Mo-Cu-C, W-C-Cu, and TiB<inf>2</inf>-Cu coatings. Tribological tests are performed and the aver-age values of the friction coefficient and wear rate of the examined systems are determined.
