Abstract
The microstructure and growth behaviors of anodic oxide layers on titanium were investigated. $TiO_2$ oxide films were prepared by anodizing at constant voltages of 180 and 200V in sulfuric acid electrolyte. The anodic $TiO_2$ layer formed at 200V showed a cell structure with more irregular pore shapes around the interface between the anodic oxide layer and the substrate titanium compared with that formed at 180V. Irregular shape of pores at the initial stage of anodization seemed to be attributed to spark discharge phenomena which heavily occurred during increasing voltages. The thickness of the anodic oxide film increased linearly at a rate of $1.9{\times}10^{ -1}\mu\textrm{m}$/min. The oxide layers formed at 180 and 200V were composed mainly of anatase structure, and the anodizing process could be suggested as one of fabrication methods of photocatalytic $TiO_2$.
