Potential And Chloride Concentration As Thresholds For Crevice Corrosion Initiation In Ss 316l, Y Shorrab, R S. Lillard

University Research

This work investigated the relationship between crevice chloride concentration ([Cl−]) and the potential necessary for initiation in stainless steel 316L (SS 316L). Real-time fluorescence measurements were used to measure [Cl−] inside SS 316L crevice assemblies as a function of bulk [Cl−] and potential. Crevice initiation at potentials slightly less than or equal to the bulk repassivation potential was associated with chloride transport, owing to passive dissolution, and an increase in the crevice [Cl−]. Once the [Cl−] within the crevice increased to the concentration necessary to initiate SS 316L pitting at the applied potential, crevice corrosion was initiated. For example, in …
