Abstract
UDC 621.9.047
Processes of the influence of low-voltage electric discharges on compact samples of tungsten-containing hard alloys are considered. In addition, conditions for obtaining composite powders of the certain phase and chemical structures, as well as their granulometric composition are analyzed. The obtained results were used when making disperse powders of tungsten-cobalt hard alloys by the electro-spark dispersion of the compact scrap of hard alloys and the hard alloys regenerated from it.
Keywords: tungsten-containing hard alloys, scrap, spark erosion dispersion, composite powders, composi-tion, structure, properties.
