SPHEROIDAL DEHYDROGENATED METALS AND METAL ALLOY PARTICLES
Methodologies, systems, and devices are provided for producing metal spheroidal powder products. Dehydrogenated and spheroidized particles are prepared using a process including introducing a metal hydride feed material into a plasma torch. The metal hydride feed material is melted within a plasma in order to dehydrogenate and spheroidize the materials, forming dehydrogenated and spheroidized particles. The dehydrogenated and spheroidized particles are then exposed to an inert gas and cooled in order to solidify the particles into dehydrogenated and spheroidized particles. The particles are cooled within a chamber having an inert gas.
