Abstract
The present application relates to a plasma atomization process and apparatus for producing metallic powders from at least one wire/rod feedstock. In the process, an electric arc is applied to the at least one wire/rod feedstock to melt the same. A plasma torch is employed to generate a supersonic plasma stream at an apex at which the electric arc is transferred to the at least one wire/rod feedstock to atomize the molten wire/rod feedstock into particles. A downstream cooling chamber solidifies the particles into the metallic powders. An anti-satellite diffuser is employed to prevent recirculation of the powders in order to avoid satellite formation. In an apparatus where two wires are fed, one wire serves as an anode, and the other as a cathode.
