Abstract: Hydrothermal treatment was used to grow oxide film on NiTi to improve corrosion resistance. The film was smooth and about 56 nm thick. X-ray photoelectron spectroscopy indicated that the surface atomic ratio Ni/Ti was reduced from 0.30 to less than 0.01 after treatment. The film was composed of Ti oxides, with a small amount of Ni. After hydrothermal treatment, corrosion resistance in Hanks' solution was significantly increased as indicated by electrochemical impedance spectroscopy and polarization tests, and crevice corrosion test.
