Abstract

An investigation of wear and failure of babbit bushes was completed in this study. The results showed that wear at dry sliding of babbit obtained by plasma spraying was less than that of babbit in the as-cast state and after a deformation heat treatment. The failure of babbit bushes was caused by a simultaneous and interrelated exhibition of fatigue and wear processes that depend considerably on cohesion strength between the bush and the bearing base and accumulation of defects on the contact surface between the bush and the shaft.
