Wear, Mechanical Properties and Corrosion Resistance of Mechanically Alloyed Ti-13Ta-6Sn

Extensive research on titanium alloys is being developed to enhance its mechanical properties, particularly for biomedical and aerospace engineering applications. Commercially Pure Titanium (CP-Ti) is a reference in these fields; however, its inherent limitations, such as moderate wear resistance, lead to the exploration of novel alloys. This study focuses on the production of a beta Ti-13Ta-6Sn alloy through high-energy milling, aiming to surpass the wear performance of CP-Ti while maintaining biocompatibility. The alloy's microstructure, phase composition, corrosion resistance, and mechanical properties were characterized. Compared to CP-Ti, the alloy exhibited a lower elastic modulus and higher yield strength. Tribological and microhardness evaluations revealed an order of magnitude lower wear rates and higher strength, highlighting the potential of this alloy in mitigating wear-related challenges.
