The modification of steel friction surface at the expense of the formation on it a surface layer implanted and compound strengthened with tungsten carbides together with the formation of a sub-layer consisting of cellular super-cooled austenite stabilized by tungsten and reinforced with tungsten carbide grid consisting of packaged nano-sized particles is considered. The influence of implanted tungsten carbides upon the formation in friction surfaces of wear-resistant structures formed during the realization of combined electro-mechanical working techniques is investigated. It is shown that at a thermo-power effect in the area of deformation takes place an intensive austenitizing of steel with the dilution of a tungsten carbide powder and further formation of composite nano-structures as a result of the dissociation of super-cooled austenite oversaturated with tungsten. There are shown results of tribotechnical tests of cylindrical samples by a normalized method.
