Abstract

본 발명은 영구 부식 방지 코팅 처리전, 특히 아연을 함유하는 산 인산 처리조에서의 인산 처리, 크롬 처리 또는 비크롬 처리전의 알루미늄 또는 알루미늄 합금 표면을 전처리하는 방법에 관한 것이다.
이 방법은 표면을 각각 또는 그의 혼합물로서 플루오라이드 음이온의 농도 100∼4000mg/l인 붕소, 규소, 티타늄, 지르코늄 또는 하프늄의 불소화 착물을 함유하고, pH 0.3∼3.5인 수성 처리 용액을 접촉시킴을 특징으로 한다. 전처리 후, 알루미늄 또는 알루미늄 합금 부품을, 필요하다면 성형후, 강 및/또는 아연 도금 및/또는 아연-합금 도금 및/또는 알루미늄 도금 및/또는 알루미늄-합금 도금 강으로 제조된 부품에 또는 서로간에 접착성 결합 및/또는 용접에 의해 결합시길 수도 있다.
