The research investigated the structure and properties of the VK10KS hard alloy after electric spark treatment utilizing the VK6-OM alloy as an electrode in the Turbo and Norma 3 technological modes. We performed scanning electron microscopy and x-ray diffraction analysis to determine the wear resistance, nanohardness, and structure of the VK10KS alloy surface layers after electric spark processing. The study revealed a change in the phase composition of the alloy associated with the formation of ditungsten carbide W2C, which contributed to an increase in the nanohardness of the surface layer with a thickness of 20 – 25 μm to 22,000 MPa. This change also improved the wear resistance of the alloy.
