标准摘要
[中文适用范围]： 本国际标准描述了一种通过阳极溶解测量金属涂层厚度的库仑法。 它仅适用于导电涂料。 表 1 给出了可通过此方法测试的涂层和基材的典型组合。 其他组合可使用当前使用的电解质进行测试（参见附录 A），或者可为它们开发新的电解质，但在这两种情况下，有必要验证整个系统的适用性。 本国际标准也适用于多层系统，例如Cu-Ni-Cr（另见8.5）。 如果适当考虑特殊特征（例如合金层的存在），它可用于测量通过各种方式施加的涂层的厚度。 在某些情况下，还可以测量扩散层的存在和厚度。 它还可用于测量圆柱形样品和线材上的涂层厚度（见 8.7）。 [外文原描述]： ISO 2177:2002 describes a coulometric method by anodic dissolution for measuring the thickness of metallic coatings. It is only applicable to conductive coatings. Typical combinations of coatings and substrates that can be tested by this method are given. Other combinations may be tested with electrolytes in current use, or new electrolytes may be developed for them but, in both cases, it is necessary to verify the suitability of the complete system. ISO 2177:2002 is also applicable to multi-layer systems, e.g Cu-Ni-Cr. It may be used to measure the thickness of coatings applied by various means, if due account is taken of special features such as the presence of an alloy layer. In some cases, the presence and thickness of diffusion layers can also be measured. It can also be used to measure the thickness of coatings on cylindrical specimens and wires.
