Abstract

Electrochemical measurements based on potentiostatic method are reviewed in this manuscript. In addition to chrono amperometric method, the potentiostatic investigations for analyzing the corrosion behaviors of passivation, localized corrosion, repassivation process on passive metals are introduced. The polarization resistance measurement which can determine the corrosion rate without breaking the specimen is also introduced.
