Abstract

Ceramic free metal powder is produced by forming a metal melt in container 16 from consumable arc electrode 15 and controlling the heat balance in the container so that a solidified metal skull is formed on the inside wall of the container the molten metal overflows from the container at 18 and is atomised by a gas stream at 19. The overflow may be heated by plasma flame 27.
