1. 范围:该规范涵盖用于形成铝及其合金表面涂层的化学转化材料。这些材料通过与铝合金表面反应生成保护性涂层。 2. 类型和形式: 类型包括含有六价铬(Type I)和不含有六价铬(Type II)。 分类包括适用于最高防腐蚀保护的1A类(Class 1A),以及用于需要低电导率的腐蚀防护3类(Class 3)。
I'm having trouble selecting a chem film class. I'm designing an avionics box that basically operates in a marine environment and is safety critical equipment. Type I is not an option for us (environmental restrictions), so I intended to callout Type II, Class 1A. There were concerns with...
Type I – Compositions containing hexavalent chromium. Type II – Compositions containing no hexavalent chromium. 1.2.2 Classes. The materials, which form protective coatings by chemical reaction with aluminum and aluminum alloys, are of the following classes (see 6.2). Class 1A - For maximum ...
