Abstract

A technological scheme and equipment for hybrid process were developed, which is based on application of the energy of supersonic plasma jet and electric arc to produce high-quality spherical powders at wire material sputtering. Performed experimental studies of the granulometric composition, morphology and technological properties of the produced powder showed that the above-mentioned process allows producing spherical powders in the range of 25…160 μm, where the share of finely dispersed fraction of 25…63 μm can be up to 70 wt.% with the coefficient of sphericity higher than 0.8, which results in high technological properties (bulk density, flowability, etc.) of the produced powders, and is extremely necessary for their application in adaptive technology sector. It is shown that the hybrid process is characterized by 2.5…6.0 times smaller specific flow rates of gas for producing 1 kg of powder and 1.25…6.0 times higher productivity, compared to other industrial technologies of plasma and electric arc sputtering.
