Title
(KO) 저융점 및 고내식성을 갖는 Ni-Cr-Fe-P계 브레이징용 합금분말 및 이의 제조 방법
Abstract
(KO)
본 발명은 저융점 및 고내식성을 갖는 Ni-Cr-Fe-P계 브레이징용 합금분말 및 이의 제조 방법에 관한 것으로서, 보다 구체적으로는 5 내지 40 중량%의 Cr, 5 내지 30 중량%의 Fe, 5 내지 20 중량%의 P, 잔부인 Ni 및 기타 불가피한 불순물을 포함하는 Ni-Cr-Fe-P계 브레이징용 합금분말 및 가스 아토마이징(Gas atomizing) 공정을 통한 Ni-Cr-Fe-P계 브레이징용 합금분말의 제조방법으로, 용해온도는 1300 내지 1650 ℃이며, 용탕노즐구경은 3 내지 10 mm이고, 가스분사압력은 3 내지 15 bar인 저융점 및 고내식성을 갖는 Ni-Cr-Fe-P계 브레이징용 합금분말의 제조방법에 관한 것이다. 본 발명에 따른 합금분말은 기존제품 대비 저융점을 가짐으로써 후처리 공정에서 접합 온도에 유리하게 작용하며, 브레이징에 적용함으로써 고기능성 접합재로서의 다양한 활용이 가능하다.
