POWDER PRODUCTION APPARATUS AND POWDER PRODUCTION METHOD USING PLASMA ROTATING ELECTRODE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a powder production apparatus 10 and a powder production method by a plasma rotating electrode method by which a particle size of powders can be refined.;SOLUTION: Plasma irradiation means 12 has a plurality of injection ports 21. The injection ports 21 are arranged so that plasma 22 can be applied from the respective injection ports 21 to one end portion 11a of an elongated electrode member 11 made of a metal or alloy. The electrode member 11 is rotated about a central axis along a length direction thereof, and the plasma 22 is applied from the plurality of injection ports 21 toward the end 11a of the rotating electrode member 11, thereby manufacturing a powder composed of a metal or alloy.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2020,JPO&INPIT
