Abstract

염욕 조성물은 질화된 철금속 단편을 포함하여 철금속 단편의 표면상의 자철광 Fe3O4의 층을 형성시켜서 부식에 대하여 밑에 있는 철을 보호하는데 사용된다. 이 층은 진한 흑색과 1000mV 이상의 부식 전위로 나타내는 바와 같이 불투과성이며 좋은 결정 정도를 갖는다. 조성물은 적어도 질산음이온과 나트륨 및 리튬양이온을 포함하며 후자는 욕에 관하여 중량비로 0.1% 내지 5% 사이, 바람직하게는 0.5% 내지 1.75% 사이이다.
바람직한 조성물은 다음 백분율 범위내에서 나트륨, 칼륨 및 리튬 양이온과 질산,탄산 및 히드록실 음이온을 함유한다.
8.5 ≤CO3 2-≤26
15 ≤NO3≤41.5
4.7 ≤OH-≤21.5
산화처리의 이례적인 신뢰성과는 별도로, 나트륨 및 칼륨과 질산 또는 탄산 음이온과 결합된 리튬의 존재는 욕내 탄산염 함유 슬러지의 형성을 감소시키는데, 아마도 조성물이 저 융점을 갖는 질산염 또는 탄산염의 삼원 혼합물을 형성하기 때문일 것이다.
