Abstract The corrosion behaviors of mild steel in simulated solutions within pits and crevices were investigated by polarization measurement s an d EIS.The results showed that the cathodic process was controlled by the diffusi on of hydrogen ion at pH 2～4,and controlled by electrochemical process at pH lo wer than 2.The anodic dissolution took place by Bockris mechanism.A critical pH value or salt concentration was not observed for mild steel.The logarithm of cor rosion rate was inversely proportional to the pH value.A small change in pH valu e within pits/crevices would result in a marked change in corrosion rate. The en richment of Cl- anions within pits/crevices would cause a decrease in pH value .

Key words: mild steel pitting corrosion crevice corrosion simulat ed solution
