Ⅳ. Electrochemical Measurements in Various Environments―Atmospheric Corrosion II （Electrochemical Impedance Method）―

Abstract

Atmospheric corrosion is a complex phenomenon that goes on under thin water film while being affected by various environmental factors. In this paper, the atmospheric corrosion researches using the electrochemical impedance method were described. The impedance characteristics under thin water film, the corrosion monitoring method using electrochemical impedance and the application example, and the corrosion monitoring research in actual outdoor environment were introduced.
