FIELD: powder metallurgy.
SUBSTANCE: invention relates to powder metallurgy, particularly to processing of wastes of tungsten-free hard alloys. Powder is obtained by electroerosion dispersion of wastes of tungsten-free hard alloy of TN20 grade in isopropyl alcohol at capacitance of capacitors of 57.5–60.0 mcF, voltage on electrodes of 140–160 V and pulse repetition rate of 200–220 Hz.
EFFECT: obtaining particles of tungsten-free hard-alloy powder with alloying elements uniformly distributed in volume.
