Abstract Metastable pitting upon 316L stainless steel was studied herein. The combination of electrochemical testing, in-situ imaging and ex-situ characterisation was carried out to address the following questions: Does each metastable pit site correspond to a single current transient or do multiple metastable pits occur at the same site? Is each recorded current transient a unique individual metastable pitting event? Does the calculated metal loss from electrochemical testing reconcile to physical damage? The results herein respond to these questions, and additionally, a user tool for analysis of metastable pitting is also presented herein.

以 316 L 不锈钢为案例研究亚稳态点蚀的原位表征

摘要 本文研究了316L不锈钢上的亚稳态点蚀。结合电化学测试、原位成像和非原位表征来解决以下问题:每个亚稳态凹坑位置对应于单个电流瞬变还是多个亚稳态凹坑出现在同一位置?每个记录的电流瞬变是一个独特的单独亚稳态点蚀事件吗?电化学测试计算出的金属损失是否与物理损坏相符?本文的结果回答了这些问题,此外,本文还提供了用于分析亚稳态点蚀的用户工具。
