Abstract On the basis of different surface treatments of a Type 316 stainless steel, results of protective film composition as obtained by Auger electron spectroscopy (AES) are related to resistance to initiation of crevice corrosion. The nickel content of the protective film was similar after all treatments, whereas the chromium surface content was found to differ between different surface treatments. A direct relationship between chromium surface enrichment and the resistance against crevice corrosion initiation was found which was independent of the presence of nonmetallic inclusions. The results suggest that initiation of crevice corrosion and initiation of pitting corrosion are different in nature.

ABSTRACTIn addition to mild steel, several stainless alloys are being proposed as materials for packages for geological disposal of high-level nuclear waste. When buried deep underground, the greatest detriment to the integrity of packages made of these alloys is localized corrosion, for which critical conditions for initiation of crevice corrosion in chloride environments, with or without other ions, need be precisely known.Crevice corrosion behavior of Type 304 stainless steel, Type 316 stainless steel, Alloy 825, Ti-Gr.1, and Ti-Gr.12 in solutions containing ions of chloride, bromide (these two for their ordinary presence in natural waters), or thiosulphate (this for the likelihood of microbially influenced corrosion) to varying concentrations have been empirically examined. All of these alloys exhibit much the same concentration dependency of crevice corrosion sensitivity for chloride and bromide ions, while Type 304 stainless steel is particularly sensitive to the thiosulphate ion. The region of insensitivity for chloride ion is wider in the increasing order of Type 304 stainless steel, Type 316 stainless steel, Ti-Gr. 1, and Ti-Gr. 12, with that of Alloy 825 lying somewhere in between.
