Abstract

The new device of crevice corrosion in high temperature water was designed. Effects of crevice geometry on corrosion behavior of 304 stainless steel during crevice corrosion in high temperature water have been investigated. Both width and length of the crevice affect the oxidation behavior of 304 SS. Different crevice widths result in different distributions of dissolved oxygen concentration and eventually affect the development of oxides within the crevice. The crevice length mainly influences the pH value within the crevice solution. The influencing mechanisms of the crevice geometry on oxidation behavior in high temperature water during crevice corrosion are also discussed.
