摘要: Abstract Metastable β-Ti alloys combine low elastic modulus, excellent mechanical strength as well good corrosion resistance. Wherever, the presence of nontoxic elements such Nb, Ta, Mo, and Zr is an important advantage. With properties this type alloy has been developed for orthopedic applications. Previous studies had shown that Ti–12Mo–13Nb Ti–10Mo–20Nb aged at 500 °C presented higher hardness/elastic modulus ratio compared to commercially Ti–6Al–4V, indicating a great potential biomedical application. However, additional are needed Therefore, objective work was analyze electrochemical behavior 500 °C/24 h 500 °C/4 h, respectively. The carried through by potentiodynamic polarization curves in Ringer’s solutions simulate body fluid. showed be more resistant when Ti–6Al–4V alloy.
