摘要

综合介绍我们已建立的具有微米空间分辨度的电化学方法,主要包括多种扫描微电极技术,并用于研究金属表面和金属/溶液界面电化学不均一性及局部腐蚀破坏过程.结果表明,这些空间分辨电化学方法的发展及应用,有助于深化对金属表面和金属/溶液界面电化学不均一性,特别是金属局部腐蚀发生、发展过程机理的认识.

Abstract

The electrochemical inhomogeneities at interface of metal/solution play an important and often controlling role in localized corrosion of metals.The traditional electrochemical techniques involving potential,current density or ac impedance measurements over bulk specimens can only provide average and general information of the interface. Thus, the development of in situ imaging techniques is essential for further characterizing electrochemical inhomogeneities at the metal/solution interface of localized corrosion system.The electrochemical techniques with spatial resolution,including scanning single micro electrode,scanning double micro electrodse and scanning micro chemical probes are reviewed.The effects of electrochemical inhomogeneities on the corrosion behavior,and the mechanism fot various localized corrosion of metals can be better understood by appropriately using these new electrochemical techniques.
