Abstract

PURPOSE: To produce a powder metallurgical metallic powder having less oxidation and carburization and excellent granular configuration by employing nonpolarized solvent or oils containing carburization suppressing reagent as an atomizing medium when molten metal in pulverized into metallic powder by an atomizing process.
CONSTITUTION: Molten metal is atomized with liquid atomizing medium into atmosphere isolated from the atmospheric air to produce metallic powder having irregular configuration and excellent green compecting properties. The atomizing medium used in this case may include for example nonpolarized solvent such as amyl benzene, xylene, or the like or mineral oil, animal or vegetable oil containing less than 30W50% of carburization suppressing reagent such as water, CO2, fatty acid, alcohol or the like. Since the atomized metallic powder is sufficiently cooled, the powder incorporates excellent green compacting properties and irregular granular configuration, less oxidation, carburization adapted for powder metallurgical stock. The atomizing medium used is isolated and recovered by multistage fluidized layers using inert gas for reuse.
