A series of Fe-xMo alloys, where x ranged from 0 to 6 Wt%, were used to determine the effect of molybdenum concentration on the repassivation kinetics of iron within a crevice. Results show that concentrations of molybdenum greater than 5 Wt% are effective in increasing the repassivation rate. Resistance of these alloys to crevice corrosion attack appears to result from the role of molybdenum in the formation of a protective salt film following breakdown of passivity within a crevice.
