Resumo: (EN) Metastable β-Ti alloys combine low elastic modulus, excellent mechanical strength as well as good corrosion resistance. Wherever, the presence of nontoxic elements such as Nb, Ta, Mo, and Zr is an important advantage. With such properties this type alloy has been developed for orthopedic applications. Previous studies had shown that the Ti–12Mo–13Nb and Ti–10Mo–20Nb alloys aged at 500 h, respectively. The electrochemical behavior was carried through by potentiodynamic polarization curves in Ringer’s solutions to simulate the body fluid. The Ti–10Mo–20Nb alloy showed to be more resistant to corrosion when compared to Ti–12Mo–13Nb alloy and the commercially Ti–6Al–4V alloy.
