Abstract The photo- electrochemical anticorrosion effect of the TiO2 films was investigated in 3% NaCl solution. The TiO2 films were prepared by using anodization method in alkaline solutions.X - ray and SEM analyses indicated that the TiO2 films were composed of amorphous and crystalline anatase, and the surface was very rough.Under UV illumination in man - made sea water,the polarzation curves and impedance spectrum of TiO2 and coupling photo - current curve between TiO2 filn and 45# carbon steel were measured. The results showed that the anodic TiO2 films had photo - electrochemical anticorrosion effect for carbon steel under UV illumination

Key words: TiO2 corrosion photo-eectrochemical anticorrosion anodization
