Electrochemical noise (ECN) has been adopted as a powerful method of studying early-stage corrosion, but there is a lack of direct in situ evidence to prove the correlation between ECN data and visual corrosion behavior. The advanced scanning reference electrode technique (SRET) assisted by electrochemical scanning tunneling microscopy (ECSTM) can detect local active sites of micro corrosion and follow their initiation and development, and can provide experimental evidence of localized corrosion at the same time as the system is monitored by ECN. To further understand the localized corrosion mechanism of metals, an in situ strategy (ECN/SRET) was developed and used to detect rapid initialization of active corrosion sites, and follow the evolution of pitting corrosion. It is expected that the ECN/SRET combination will prove to be a powerful tool for in-depth studies of localized corrosion.

电化学噪声（ECN）已被用作研究早期腐蚀的有效方法，但是缺乏直接的现场证据来证明ECN数据与视觉腐蚀行为之间的相关性。先进的扫描参比电极技术（SRET）借助电化学扫描隧道显微镜（ECSTM）辅助，可以检测出局部的微腐蚀活性部位并跟踪其发生和发展，并可以在监测系统的同时提供局部腐蚀的实验证据由ECN。为了进一步了解金属的局部腐蚀机理，开发了一种原位策略（ECN / SRET）并将其用于检测活动腐蚀部位的快速初始化，并跟踪点蚀的发展。
