Abstract:

The influence of Clˉ concentration and acidity to the polarization curves of iron electrode is measured. The kinetic parameters of the anodic and cathodic process of iron electrode is obtained. And the corresponding reaction mechanisms is suggested. The theoretical values of corrosion parameters are in agreement with the experimental values.

Key words: Chloride acid, Chloride ion, Iron;Corrosion mechanism, Electrochemistry process
