Abstrakt: 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 (MoC and WC) and titanium boride (TiB) are observed in Mo-Cu-C, W-C-Cu, and TiB-Cu coatings. Tribological tests are performed and the aver-age values of the friction coefficient and wear rate of the examined systems are determined. [ABSTRACT FROM AUTHOR]
