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.
