Abstract

(목적)
니켈 또는 코발트로 예비플래시 처리를 필요로 하지 않는 단일 공정의 크로메이트 처리에 의해 아연함유금속도금강판위에 내흑변성과 내백청성이 우수한 크로메이트피막층을 형성시키는 것이다.
(구성)
Cr6+이온, CR3+이온, 무기산(질산및/또는 황산) 및 추가의 금속이온 예를 들면, Zn, Ni, Co 및/또는 Al 이온으로 이루어지고, Cr3+/Cr6+의 몰비가 1/9 내지 4/1이고, 무기산/전크롬이온의 몰비가 0.1/1내지 2/1이고 및 추가의 금속이온/무기산의 몰비가 0.05/1 내지 1/1이고, 필요에 따라 0.3/1 이하의 인산이온/전크롬이온의 몰비로 인산이온을 함유하는 크로메이트코팅액을 아연함유금속도금강판에 도포하고, 금속크롬으로 환산하여 10 내지 200㎎/㎡의 양만큼 크롬피막층을 형성하기 위해 수세없이 건조시킨다.
