Tribological Behavior of homogenized and aged Ti~55.5wt%Ni Alloy

In this research, the effect of homogenizing and aging on the tribological behavior of the Ti-55.5wt%Mi alloy was investigated. The alloy was homogenized at 1000C. The aging carried out at a temperature of 700°C for one hour after solution annealing at 1OOOC and then were quenched in ice- water. Wear tests were performed on a pin-on-disk tribometer under dry sliding condition. The results showed that as the load was increased from 20 to 60 N the wear was decreased by about 50%. Scanning electron micrographs of the worn surfaces indicated a compact oxide layer was formed on the surface under higher loads which led to a decrease in wear.
