초록

Metastable β titanium alloys have been used in implants due to their high specific strength and excellent corrosion resistance. However, the high cost of β-stabilizing elements limits the application of metastable β titanium alloys. Consequently, research has been conducted on low-cost metastable β titanium alloys using relatively inexpenisve β-stabilizing elements such as Mo and Fe. This study analyzes the wear resistance of Ti-5Mo-xFe (x=2,4 wt%) alloys, designed and manufactured as low-cost metastable β titanium alloys. The wear mechanisms of Ti-5Mo-xFe alloys were identified through ball-on disk testing and observation of the worn surfaces. Additionally, the influence of Fe addition on the microstructure and the resulting changes in wear resistance were examined. The wear resistance of the Ti-5Mo-xFe alloys were evaluated in comparison to the Ti-6Al-4V ELI alloy.
