EXPERIMENTAL INVESTIGATION OF WEAR BEHAVIOUR ON SINTERED TI6AL4V/YTTRIUM OXIDE NANO-COMPOSITE

Wear behavior of yttrium oxide reinforced titanium alloy (Ti6Al4V) was studied under the dry sliding condition at room temperature. Wear is the major drawback for the modern components made with titanium alloy to the advanced applications. Wear rate was determined by considering the sliding distance, sliding velocity and applied load by using pin-on-disc. The composite pin surface was sliding against the oil hardened non-shrink (OHNS) steel surface at the velocity range between 0.6 to 1.2 m/s for sliding distance of 1600m by varying the load from 5 to 10N. Wear rate is changing directly proportional to the applied load and sliding velocity. The composite having 2%.wt. of yttrium oxide reinforced shows better wear resistance as compared to the 1 and 3%.wt.of reinforcement.
