Experimental study of new titanium alloy Ti-6Al-4Fe for biomedical application

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
