Abstract
Fretting fatigue tests under a pad-span of 30mm and a contact pressure of 20MPa were carried out using a 2618 aluminum alloy to investigate the effect of test temperature (at room and 423,463K) on fretting fatigue strength. Irrespective of test temperature, the fretting fatigue strength was reduced to one quarter of the plain fatigue strength under the stress ratio R = 0.0. Also, fretting fatigue tests were carried out using for MoS_2 + PTFE coating pad and specimen with shot-peening. As a result, MoS_2+PTFE coating and Shot-peeninng improved fretting fatigue strength.
