Abstract: Anodic oxide films on titanium formed by electrochemical methods have been widely applied in various areas，such as corrosion protections，photocatalytic engineering，solar cells，sensors and biomedical engineering due to their high corrosion resistance，good biomedical compatibility and photocatalytic activity. The performance of TiO2 films strongly depend on the structure，and　crystalline TiO2 had better applicable properties than the amorphous form. In this paper，the effect of anodic oxidation parameters， such as potential，electrolyte (type，concentration and temperature)，Ti substrate，film growth mode and film growth rate on the crystallization behavior of TiO2 films were discussed. It was revealed that raising oxidation potential，increasing solution temperature，prolonging anodizing time and increasing concentration of electrolyte were beneficial to the formation of crystalline titanium oxides on the anode，while crystallization was suppressed by incorporation of impurity ions (electrolyte anions or alloying elements) or increasing film growth rate.
