| Abstract Scope |
Due to their biomedical benefits, titanium alloys are widely used as promising biomaterials. The best-suited qualities are found in alloys with a beta-titanium structure. This study presented three Ti-Cr-based alloys containing 0, 8, and 20 wt. % Zr additions, aiming to develop a novel beta-type titanium alloy. Spark plasma sintering was used to synthesize the alloys, and the microstructure, phase composition, nanomechanical, and electrochemical properties were analyzed. The study found that Ti-20Cr-8Zr had ~11% higher nanohardness than pure Ti-Cr alloy and ~21% higher than Ti-20Cr-20Zr. Ti-20Cr-20Zr alloy has the lowest and most preferred elastic modulus. Also, Ti-20Cr-20Zr exhibited the best electrochemical performance in Hank’s solution, with a polarization resistance of 7477.7 Ω and a lower corrosion rate of 0.090346 mm/yr. This research indicated that alloying 20 wt. % Zr with a Ti-20Cr alloy can yield a non-toxic β-titanium alloy with enhanced nanomechanical and electrochemical properties well-suited for biomedical applications. |
