abstract = "The effects of Cu2+, Fe2+ and Fe3+ ions on the uniform and pitting corrosion of Ti are studied in NaCl solutions at temperatures from 125 to 175°C. It is found that the hydrolysis of metal chloride salts plays an important role in the corrosion of Ti by lowering the pH values of solutions. For uniform corrosion, the polarization resistance Rp of Ti in NaCl solutions with different additions follows the same decreasing sequence as the pH values of these solutions: no addition > CuCl2 > FeCl2 > FeCl3. As to pitting corrosion, it is confirmed that the presence of oxidizing metal ions can cause severe pitting on Ti. Cyclic potentiodynamic polarization curves show that Ti pits upon anodic polarization in NaCl solutions with metal ion additions at 150 and 175°C; not at 125°C. The values of the breakdown potential Eb follow the decreasing sequence: no addition > FeCl2 > FeCl3 > CuCl2 at 150°C, and no addition > FeCl3 > FeCl2 > CuCl2 at 175°C. Ti is more susceptible to pitting corrosion in NaCl solutions with Cu2+, Fe3+ and Fe2+ chlorides at 150 and 175°C.",
