标准范围

本文件规定了通过硫酸铜接触试验检查铝及其合金上薄阳极氧化涂层连续性的方法。该方法的使用仅限于厚度小于5μm的阳极氧化涂层或已变形的涂层，包括线圈阳极氧化技术产生的涂层。注:所述方法可快速检查铝及其合金上铝氧化薄层的连续性。如果对涂层表面的可见缺陷存在疑问，使用该方法可以验证该缺陷是否与暴露裸金属的涂层中的局部间隙相对应。

This document specifies a method for checking the continuity of thin anodic oxidation coatings on aluminium and its alloys by a copper sulfate contact test.The use of this method is limited to anodic oxidation coatings of thickness less than 5 μm or coatings that have been deformed, which includes those produced by coil anodizing techniques.NOTE The method described enables a rapid check to be made for the continuity of a thin coating of aluminium oxidation on aluminium and its alloys. In cases of doubt regarding a visible fault on the surface of a coating, the use of this method makes it possible to verify whether the fault corresponds to a local gap in the coating that exposes bare metal.
