FIELD: powder metallurgy.
SUBSTANCE: invention relates to powder metallurgy, particularly, to production of hard-alloy powders. It can be used in processing wastes of hard alloys. Powder is obtained by electric erosion dispersion of “Т30К4” hard alloy wastes in diesel fuel with capacitance of capacitors of 64 mcF, voltage on electrodes of 185–200 V and pulse repetition rate of 180–220 Hz.
EFFECT: obtaining powder with uniform distribution of alloying elements.
