Abstract

The use of the technology of combined electromechanical processing, consisting of a high-temperature plastic deformation mode, when tungsten carbide powder is implanted into the surface of carbon steel, and a high-temperature thermal hardening mode, during which tungsten carbides are partially dissolved in the austenite of steel up to the limit of its saturation with tungsten, provided a gradient wear-resistant three-layer highly dispersed structure as a result of the decomposition of supercooled austenite oversaturated with tungsten. The results of tribotechnical tests of cylindrical specimens by the normalized method are presented.
