The Effect of the Contact Conditions and Surface Treatments on the Fretting Fatigue Strength of Medium Carbon Steel

摘要

Fretting fatigue tests characterized with employing a contact bridge pad clamped to a fatigue specimen were conducted to find the effect of shapes of contact pads. The shapes of the contact edge of the pad used in the test were sharp and round. The relative slip amplitude during fatigue testing was measured and the effect of the location of the displacement sensor was discussed with the result of the stress analysis around the contact area. The effect of molybdenum coating on the fretting fatigue strength was also investigated.
