Development of Electrochemical Studies in Microzone of Metallic Corrosion (1) Scanning Electrochemical Microscopy

In the recent years,with the development of electrochemical theory as well as measurement and testing technology for microzones,microzone techniques are very important measurement methods widely used in corrosion areas.In this paper,the basic principle of scanning electrochemical microscopy is describe.Especially the application of this technique in the studies of metallic corrosion is illustrated.
