ABSTRACT:
A method for producing atomized metal particles, particularly of titanium-base alloys and superalloys, that are free from contamination by foreign material; this is achieved by providing a rod of the metal to be atomized and contacting an end portion of the rod with a plasma arc gas jet which simultaneously melts and atomizes the metal from the rod to form the atomized particles and preventing contamination of the particles.
