SECM基本原理及其在金属腐蚀中的应用

Basic Principles and Applications of SECM in Metal Corrosion

扫描电化学显微镜(SECM)是一种具有较高空间分辨率的化学显微镜,在成像和动力学研究已经广泛应用.本文简要介绍SECM基本原理,综述2009年以来SECM在腐蚀方面的应用,包括扫描成像和异相电子转移化学活性的研究,并简要介绍了作者课题组在SECM方面的研究工作,展望SECM在腐蚀研究的应用.

Scanning electrochemical microscopy （SECM） is chemical microscopy with higher spatial resolution. After 24 years of development, SECM has been widely applied in mapping and kinetics study of heterogeneous electron transfer in localized processes at solid-liquid or liquid-liquid interfaces. The fundamentals and recent advances of SECM in corrosion applications are described, including SECM mapping and kinetics on localized corrosion of metal or coating, Research work of SECM in corrosion by our group is also introduced. Future applications of SECM in corrosion are highlighted.
