摘要
The present invention relates to an apparatus for producing a composite metal powder using a gas atomization process, and to a method for producing a composite metal powder using same. More particularly, to accomplish the above aim, the present invention relates to an apparatus for producing a composite metal powder using a gas atomization process, comprising: a housing; a crucible accommodated in the housing and containing molten metal; an induction coil arranged along the outer surface of the crucible; an atomizing nozzle connected to the crucible to spray the molten metal in the crucible; a dissolving chamber containing the materials sprayed by the atomizing nozzle; a gas discharge system which discharges argon (Ar) gas or a gas mixture of nitrogen and oxygen; and a lower chamber communicating with the dissolving chamber to collect composite metal powder. The present invention also relates to a method for producing a composite metal powder using a gas atomization process, comprising: (a) a titanium carbide preparation step of injecting carbon into a molten metal mixture of aluminum (Al) and titanium (Ti) to prepare titanium carbide (TiC); (b) an ingot-forming step of forming an ingot of the titanium carbide (TiC) prepared in step (a) and aluminum-silicon (AlSi); (c) an injecting step of injecting the ingot of the titanium carbide (TiC) and aluminum-silicon (AlSi) formed in step (b) into the crucible; (d) a heating step of enabling a cylindrical heating coil arranged along the periphery of the crucible to heat the ingot injected into the crucible in step (c) in order to prepare molten metal by high frequency induction heating; (e) a flowing step of enabling the molten metal prepared in step (d) to flow into the nozzle; (f) a spraying step of spraying argon (Ar) gas or a gas mixture of nitrogen and oxygen from the end of the nozzle; and (g) a collecting step of collecting the composite aluminum powder containing titanium carbide (TiC) prepared through step (f).
