... Abstract An investigation of wear and failure of babbitt bushes was completed in this study. The results showed that wear at dry sliding of babbitt obtained by plasma spraying was less than that of babbitt in the as-cast state and after a deformation heat treatment. The failure of babbitt...

... in temperature. The material was a steel in the normalized condition with a 0.35% C content. It appears probable that deficient lubrication of the gland resulted in overheating of the rod due to friction. The presence of a sprayed-metal coating was probably an additional factor in promoting failure, as it would...

For example, according to ASTM G155 cycle 1, a test cycle consists of a 102-minute drying phase followed by an 18-minute spray phase ( Ref 18 ). In most published test standards, the spraying...
