FIELD: metallurgy.
SUBSTANCE: copper powder is subject to action of high-frequency plasma of reduced pressure by introducing it to plasma jet at pressure of 1.33 - 133 Pa. Plasma-forming gas consists of argon and air. Its action on powder is performed at voltage of 7.8-8.0 kW, current force of 1.3-1.5 A and at copper powder flow rate of 0.08-0.1 g/sec. Obtained powder is mixed with zinc stearate, workpieces are pressed, loaded to shaft furnace and sintered in dissociated ammonia environment. Cooling is carried out in the air in dissociated ammonia environment.
EFFECT: improvement of the method.
