and Astronautics, Nanjing 210016, China) Abstract: Self-organized TiO2 nanotube arrays were fabricated by anodic oxidation of a pure titanium sheet at constant potential. The results show that TiO2 nanotube arrays are regularly obtained when anodizing voltages ranges from 10 to 20 V, anodizing time keeps more than 5 min and HF concentration is 0.5%. The average diameter and length of the tube......
