Abstract

The effects of frictional wear characteristics on fretting fatigue strength of Ti-4.5Al-3V-2Mo-2Fe conducted with various annealing treatments were investigated in this study. The weight loss tends to increase with decreasing the hardness. The estimated weight loss of the slip region at high cycle fretting fatigue life region tends to increase with increasing the length of the slip region. The fretting fatigue life tends to decrease with increasing the length of the slip region and increasing the estimated weight loss of the slip region. The depth of the crack growth zone caused by the contact pressure at high cycle fretting fatigue life region tends to increase with increasing the estimated weight loss of the slip region. The fretting fatigue life tends to decrease with increasing the estimated weight loss of the slip region and increasing the depth of the crack growth zone caused by the contact pressure.
