Abstract: The corrosion behavior of Ti-2A1-2.5Zr alloy with 5 alloy contents and 5 surface states were studied in water steam at 400℃, 10.3 MPa for 72 h. The weight-increments of all samples are under 4 mg/dm2, better than Zr and Zr-alloy. α-Ti is oxidized into anatase-type TiO2 preferentially. The corrosion resistance is improved by adding Al element or pre-oxidizing treatment, the latter is more effective relatively.
