Production of dispersed powders of tungsten-cobalt by spark erosion dispersion of compact samples of hard alloys, including scrap

Abstract

The processes of the influence of electrical low voltage discharges on compact samples of tungsten-containing hard alloys and the conditions of producing composite powders with a fixed phase and chemical composition and size grading are considered. The obtained results have been used to manufacture dispersed powders of tungsten-cobalt hard alloys by spark erosion dispersion of compact scrap and regenerated hard alloys.
