Abstract: front page image
(EN)A method for preparing a metal powder is provided. The method for preparing a metal powder comprises the steps of: preparing a first metal powder; preparing a second metal powder, in which the first metal powder is agglomerated, by agglomerating the first metal powder; coating the second metal powder with an organic binder; and preparing a third metal powder, which has higher fluidity than that of the second metal powder coated with an organic binder, by agglomerating and coarsening the second metal powder coated with an organic binder.
(FR)L'invention concerne un procédé de préparation d'une poudre métallique. Le procédé de préparation d'une poudre métallique comprend les étapes consistant à : préparer une première poudre métallique ; préparer une deuxième poudre métallique, dans laquelle la première poudre métallique est agglomérée, par agglomération de la première poudre métallique ; recouvrir la deuxième poudre métallique avec un liant organique ; et préparer une troisième poudre métallique, qui présente une fluidité supérieure à celle de la deuxième poudre métallique recouverte d'un liant organique, par l'agglomération et le fait de rendre plus grossière la deuxième poudre métallique recouverte d'un liant organique.
(KO)금속 분말의 제조 방법이 제공된다. 상기 금속 분말의 제조 방법은, 제1 금속 분말을 준비하는 단계, 상기 제1 금속 분말을 응집시켜, 상기 제1 금속 분말이 응집된 제2 금속 분말을 제조하는 단계, 상기 제2 금속 분말을 유기 바인더로 코팅하는 단계, 및 상기 유기 바인더가 코팅된 상기 제2 금속 분말을 응집 및 조대화시켜, 상기 유기 바인더가 코팅된 상기 제2 금속 분말보다 높은 유동성을 갖는 제3 금속 분말을 제조하는 단계를 포함한다.
