Abstract Repassivation behavior behavior of 316Lstainless steel in fretting has been studied in different NaCl solutions.And the effect of crevice corrosion occurring during fretting process had been discussed.The results showed that different solutions resulted in different repassivation behavior.But the difference of repassivation behaviors in different solutions ras not remarkable:in pH10.0(0.9% NaCl)solution,repassivating process could last for about 5×10 4 cycles;while fretting in other corrosive solutions,no more repassivation process took place after 4×10 4 cycles.When fretting was carried out in deionized water the material had better repassivation ability. The growing film might take up 17 percent of passive film in static condition.The evidence suggested that passive film could not protect the material from corrosion damage effectively in fretting
