Plasma Rotating Electrode Process Powder Tổng quan
The plasma rotating electrode process (PREP) is a unique powder production technique that utilizes a rotating electrode to generate a plasma arc. This arc melts and atomizes the electrode material, creating spherical metal powder particles with exceptional properties. PREP powders are widely used in additive manufacturing, powder metallurgy, and thermal spraying applications.
