In situ monitoring of crevice corrosion morphology of Type 316L stainless steel and repassivation behavior induced by sulfate ions
•Repassivation of crevice corrosion on Type 316L was observed when the solution was changed from 1M NaCl to 0.88M Na2SO4 or to 1M NaCl-0.88M Na2SO4.•The active dissolution of Type 316L stainless steel in 1M NaCl at pH 0.4 was slightly suppressed by SO42− ions in anodic polarization measurements.•The...

To analyze the repassivation mechanism induced by SO42− ions, in situ monitoring of the crevice corrosion morphology on Type 316L stainless steel was performed. The repassivation of the crevice corrosion was observed when the solution was changed from 1M NaCl to 0.88M Na2SO4 or to 1M NaCl-0.88M Na2SO4. The active dissolution of Type 316L stainless steel was suppressed by SO42− ions at pH 0.4 in anodic polarization measurements. The transition from active to passive states inside the crevice was likely promoted by SO42− ions. |
