Abstract
Incorporation of TiC particle was adopted as one of the available methods to study the enhancement in tribological and mechanical properties of Ti-6A14V alloy. The mechanical performance of Ti-6A1-4V-10Vol%TiC sample (TMC) was evaluated using tensile and micro-scratch tests. Ball-on-disk tests at various loads revealed that the wear resistance of Ti-6A1-4V was improved via incorporation of TiC provided that the contact pressure remained lower than 0.98 GPa. Thermal oxidation was adopted to improve the high pressure wear resistance of TMCs. The optimum oxidation condition was characterized using XRD, SEM observations, and micro-scratch tests. The fracture toughness of the coatings was measured by micro-indentation tests. Ball-on-disk tests revealed that oxidation at the optimum condition (at 800°C for 20 min) significantly improved the wear resistance of the TMCs compared to uncoated TMCs. The mechanism and the effect of oxidation process were analyzed and the operative wear mechanisms at different loads were discussed.
