Corrosion Resistance of ultrafine-grained (UFG) titanium alloys fabricated by equal channel angular pressing (ECAP) was investigated in this study. Electrochemical measurements of pure Ti and Ti-6Al-7Nb alloy were conducted in 3.5 wt.% NaCl and Ringer’s solution separately. Results indicated that both ultrafine-grained pure Ti and Ti-6Al-7Nb alloy had much lower corrosion current density than annealed coarse-grained counterparts in the specified corrosive environment.
