Fretting fatigue test of NiCrMoV(JIS-SNCM439) was carried out using pads of same material and specimens of three kinds of height. There was little difference in the time strength of fretting fatigue between the heights of specimen, however a slight difference in the fatigue limits was observed: the fretting fatigue limit increases slightly as the height of specimen is extremely smaller. Fretting fatigue strengths in overall life range were successfully predicted by using an assumed stress-strain curve on the pad material for considering the deformation of contact surface by fretting wear.
