Of key interest was the trends of corrosion potential on initial period. Corrosion potential–time measurements were undertaken after the samples exposed to the air for 24 h were polarized anodically and cathodically in acetic acid solution. With analyzing of the curves of electrochemical polarization and SEM and EDS data of the samples ,corrosion and electrochemical behavior and mechanism of localized corrosion of 316L stainless steel in acetic acid solution with Cl- were discussed.
