Abstract: Recent studies have focused on the development of metastable beta-type Ti alloys with non-toxic elements such as Nb, Ta, Mo and Zr for biomedical applications. These alloys present low modulus, good mechanical compatibility and good corrosion resistance. Moreover, the processing variables can be controlled to produce microstructures with specific properties. In this regard, the objective of this work was to analyze the electrochemical behavior of Ti-13Nb-12Mo alloy hot forged and aged at 500 °C/24 h. The microstructure was analyzed by transmission electron microscopy. The corrosion tests were carried out under a NaCl solution at a temperature of 25 °C. The results showed that under the conditions studied Ti-12Mo-13Nb alloy exhibited passivation, which is desirable for corrosion resistance. Therefore the alloy is a potential alternative for the of Ti-6Al-4V used in orthopedic implants
