Rotating electrode atomization for the production of fine powders from reactive metals

摘要

Gas atomization has been successfully coupled with the rotating electrode process (REP).The rotating electrode serves mainly as a non-contaminating means of containing and delivering the melt in a controlled manner to the atomization gas flow.To date various iron and titanium alloys have been atomized by htis technique.powder yields are greatly improved over the rotating electrode process alone and appear to match those of conventional gas atomization,while circumventing the issues of crucible reactions and need for cold hearth melting.
