Electrode materials for electrospark alloying of machine parts

Abstract

The conditions of producing tungsten alloys with chromium and molybdenum by thermal reduction methods of a scheelite concentrate with the additions of oxides of alloying elements are studied. The application of W–Cr and W–Cr–Mo alloys for electrospark alloying of the surface of machine parts increases the wear resistance of the parts 1.5–2 times.
