A study on the influence of anodizing time, annealing temperature and photoelectrochemical properties of TiO 2 nanotube (TiO 2 NT) has been investigated. The crystallinity was investigated using X-Ray Diffraction and the anti-corrosion performance of stainless steel 304 (SS 304) coupled with TiO 2 NT was evaluated using electrochemical techniques under ultraviolet exposure. The optimum anodizing condition occurs at a voltage of 20 V for 3 h. After anodizing, the TiO 2 NT amorf was calcined at 500 °C to obtain anatase crystalline phase. For the photoelectrochemical property, the effects of pH and NaCl concentration on corrosion prevention have been examined. The result showed that the corrosion rate of stainless steel 304 coupled with TiO 2 NT can be reduced up to 1.7 times compared to the uncoupled stainless steel 304 (3.05×10 -6 to 1.78×10 -6 mpy) under ultraviolet exposure by shifted the photopotential to the more negative value (-0.302 V to -0.354 V) at a pH of 8 and 3% NaCl concentration (-0.264 V to -0.291 V). In conclusion, the TiO 2 NT films, which was prepared by anodization and followed by annealing can prevent the corrosion of stainless steel 304.
