Zusammenfassung:The present invention relates to a method for manufacturing a porous metal support using metal powder injection molding and uniaxial compression molding. The present invention may comprise, in sequence, the steps of: (1) pretreating a metal powder and a binder; (2) injection molding a mixture of the pretreated metal powder and the binder in the form of a disc; (3) removing the binder from the disc; (4) firing the disc from which the binder has been removed; (5) uniaxially compressing the fired disc; (6) controlling the surface of the uniaxially compressed disc; and (7) depositing a separation film on the surface of the surface-controlled disc. The porous metal support manufactured by the present invention can be applied to various raw materials, can have a uniform surface pore size, and can be mass-produced. La présente invention concerne un procédé de fabrication d'un support métallique poreux par moulage par injection de poudre métallique et moulage par compression uni-axiale. La présente invention peut comprendre, en séquence, les étapes suivantes : (1) prétraitement d'une poudre métallique et d'un liant; (2) moulage par injection d'un mélange de la poudre métallique prétraitée et du liant sous la forme d'un disque; (3) retrait du liant du disque; (4) cuisson du disque duquel le liant a été retiré; (5) compression uni-axiale du disque cuit; (6) commande de la surface du disque à compression uni-axiale; et (7) dépôt d'un film de séparation sur la surface du disque à surface commandée. Le support métallique poreux fabriqué selon l'invention peut être appliqué à diverses matières premières, peut avoir une taille de pore de surface uniforme, et peut être produit en masse. 본 발명은 금속분말사출성형과 단축 압축성형을 이용한 다공성 금속 지지체 제조방법에 관한 것으로, 본 발명은 ① 금속분말과 바인더의 전처리, ② 전처리된 상기 금속분말과 상기 바인더의 혼합물을 디스크 형태로 금속분말사출성형, ③ 상기 디스크로부터 상기 바인더를 탈지, ④ 바인더가 탈지된 상기 디스크를 소성, ⑤ 소성된 상기 디스크를 단축 압축, ⑥ 단축 압축된 상기 디스크의 표면 제어, 및 ⑦ 표면 제어된 상기 디스크의 표면에 분리막 증착하는 단계를 순차적으로 포함할 수 있다. 본 발명을 통해 제조된 다공성 금속 지지체는 다양한 원재료의 적용이 가능하고 균일한 표면 기공 사이즈를 가질 수 있으며, 대량생산이 가능하다.
