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. The results suggest that initiation of crevice corrosion and initiation of pitting corrosion are different in nature.
