This work investigates the corrosion and tribocorrosion behavior of alfa + beta Ti-12Nb alloy processed by castingand sintering, in 9 g/l NaCl solution at body temperature, and compares the results with the commercial Ti-6Al-4 V alloy. Different electrochemical techniques were used to access the corrosion behavior. Tribocorrosion behavior was studied at open circuit potential under continuous and intermittent sliding, and at anodic potentiostatic condition under continuous sliding. Results revealed that Ti-12Nb alloys presented similar tribo-corrosion behavior although the sintered one exhibited a better corrosion behavior. Nevertheless, Ti-6Al-4 Vpresented better overall degradation resistance than both Ti-12Nb alloys.
