Abstract:
Titanium (Ti) and its alloys are used extensively in biomedical applications based on their high specific strength, excellent corrosion and tribological resistance. To overcome the potential V toxicity, V was replaced by Nb and Fe, leading to two new V-free α+ β-type Ti-based alloy, i.e., Ti-6Al-7Nb and Ti-5Al-2.5Fe. The purpose of this study is to evaluate the friction and wear behavior of high-strength titanium based alloy. The Oscillating friction and wear tests have been carried out in ambient air under different conditions of normal applied load and sliding speed, as a counter pairs we used the ball of 100Cr. The surface morphology of the titanium alloys have been characterized by SEM, EDAX, micro hardness, roughness analysis measurements
