Abstract The initiation, growth, and repassivation of metal/metal crevice corrosion of lCr18NigTi steel in aqueous 0.03%, 0.3%and 3%NaCl solutions were investigated. Laboratory date indicate: (1) There exists a critical potential V_(CREV) for crevice corrosion. When a specimen is polarized to a potential more positive than V_(CREV), crevice corrosion is likely to grow. When polarized to a value more negative than V_(CREV), crevice corrosion can still occur but the specimen soon becomes repassivated. The repassivation potential of the specimen E_R, is a characteristic value depending on the geometry of the crevice configuration. The lower limit of E_R coincides with that of V_(CREV), (2) The initiation of crevice corrosion follows probability statistics. The initiation probability is found to have a stable value under specified conditions. This probability is another characteristic of crevice corrosion and is independcnd of E_R, (3)The growth (development) of crevice corrosion becomes accelerated with rise in temperature and potential but in different ways.
