Wear-Resistant Coatings on WC–Co Hard Alloys Synthesized by Concentrated Energy Flows

Abstract

The paper presents the results of surface reinforcing of tungsten carbide alloys using various technologies: deposition of ion–plasma TiN + ZrN coating with a nanohardness of 38 GPa, production of a hard-alloy plate with a gradient structure by the method of electroerosion reinforcing by doping that consists of a more wear-resistant surface layer of VK6-OM and a durable but insufficiently wear-resistant VK10KS base, one- and multicomponent surface modification of the surface of VK10KS hard alloy with a low friction coefficient of μ = 0.1 by an electroexplosive doping method (at the friction coefficient of starting alloy of μ = 0.41).
