Plasma Rotating Electrode Process (PREP) is a process in which plasma arcs and melts the end of a high-speed rotating electrode rod, and uses the centrifugal force generated by the high-speed rotation of the electrode rod to throw out the molten metal and atomize it into fine droplets. The atomized metal droplets are condensed into spherical powders after heat exchange with the atmosphere.

Plasma Rotating Electrode Atomization Powdering (PREP) has unique process technology advantages. Together with atomization powdering methods (VIGA, EIGA, PA), it is one of the mainstream processes on the market. Plasma Rotating Electrode Powdering Technology is one of the important technologies for producing high-quality spherical metal powders. It uses the centrifugal force generated by the high-speed rotation of the electrode to throw out the liquid film to form droplets, which are atomized and solidified into spherical powders in an inert atmosphere.
