Ⅳ. Electrochemical Measurements in Various Environments―Electrochemical Reaction of Stainless Steels under Marine Environments with Microorganisms―

Abstract

The examples for the measurement using electrochemical technique in seawater environment are described in this article, especially in the natural seawater which contains the microorganisms. The noticeable feature of the electrochemical behavior of stainless steels in the natural seawater is the ennoblement of open circuit potential （Ecorr）, and this ennoblement can be considered as the fundamentals of Microbiologically Influenced Corrosion （MIC） of stainless steels in natural seawater.
