Fretting fatigue tests were carried out on SUS304 austenitic stainless steel by plain bending. The specimens were set with Al_2O_3 ceramics or SUS304 contact pads. Corrosion fretting fatigue tests were also carried out by dripping them in salt water. From the test results, when the specimen was set with SUS304 pads, the fatigue limit decreased slightly in salt water as compared with that in air. However, with Al_2O_3 pads, the fatigue limit decreased significantly in salt water. This is because the specimen was abraded by Al_2O_3 pad and then the wear debris were washed away by salt water. The distinctive feature of failure in salt water was that the failure occurred near the center of fretting area as a result of the slipping region moving inward the contact area.
