Effect of fretting regimes on the fretting corrosion behavior of stainless steel in artificial crevices

Fretting crevice corrosion at the fastening interfaces of stainless -steel products is an unavoidable issue in the medical, marine, and nuclear industries. In this study, the effects of the fretting regimes on the fretting corrosion in artificial crevices were investigated, and the results showed that fretting initiated severe corrosion inside the crevice under the stick regime. Under the stick-slip and slip regimes, the volume loss was dominated by fretting corrosion, without initiating crevice corrosion.
