The layer-by-layer electrospark deposition of Cu, In, Pb, Cd, and Sn group metals and Ti, V, and W metals, as well as their carbides and hardmetals of WC type, onto metallic surfaces is studied. This technique improves the quality and wear resistance of the surface layer compared to coatings without a sublayer. The sintered electrode materials containing 10–30 wt.% of the (Ni–Cr–Si–B)–WC6 alloy allow...
