FIELD: powder metallurgy.
SUBSTANCE: invention relates to powder metallurgy, particularly, to processing of wastes of tungsten-free hard alloys to produce powder. To obtain powder, wastes of tungsten-free solid alloy of grade TH20 are subjected to electric erosion dispersion in distilled water with capacitance of capacitors of 60.0-62.5 mcF, voltage on electrodes of 120-140 V and pulse repetition rate of 120-140 Hz.
EFFECT: obtaining particles of tungsten-free hard-alloy powder with alloying elements uniformly distributed in volume.
