标准摘要
[中文适用范围]： 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5微米的阳极氧化涂层或已变形的涂层，其中包括通过卷材阳极氧化技术产生的涂层。 注：所描述的方法可以快速检查铝及其合金上薄薄的铝氧化涂层的连续性。 如果对涂层表面上的可见缺陷有疑问，使用此方法可以验证该缺陷是否对应于暴露裸露金属的涂层中的局部间隙。 [外文原描述]： 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.
