金属和合金的腐蚀.腐蚀测量用多电极阵列

[中文适用范围]： 本文件规定了使用多电极阵列测量金属及其合金的腐蚀，特别是局部腐蚀的方法学。它可作为研究局部腐蚀发生和传播过程的强大工具。它还可用于现场长期腐蚀监测，特别是在局部腐蚀的情况下，并为不同成分和/或物理性质的金属在不同环境中的评估以及大量抑制剂的筛选获得高通量结果。此外，可以通过多电极阵列评估异种金属配对的伏安偶联电流和电势分布。多电极阵列可以实现实现完全浸没、薄膜、喷洒和湿-干循环暴露。本文件不打算用于测量非电化学机制引起的腐蚀。 [外文原描述]： This document specifies the methodology of using multielectrode arrays for the measurement of the corrosion, especially localized corrosion, of metals and alloys. It can be used as a powerful tool for studying the initiation and propagation processes of localized corrosion. It is also a useful tool for long-term corrosion monitoring in the field, especially for localized corrosion, and for obtaining high throughput results for the evaluation of metals with different compositions and/or physical properties in different environments and the screening of a large number of inhibitors. Additionally, the galvanic coupling current and potential distribution of dissimilar metal parings can be assessed by multielectrode arrays. Multielectrode arrays can be implemented in full-immersion, thin-film, spray and alternating wet?dry cycle exposures. This document is not intended to be used for measurements of corrosion caused by a non-electrochemical mechanism.
