摘要（英）：

The invention discloses a method for preparing a nanostructured bioactive oxide film on the titanium alloy surface. The method comprises the steps of ultrasonic shot peening of titanium alloy and induction heating oxidation treatment, wherein ultrasonic shot peening of the titanium alloy is characterized in that the titanium alloy is treated for 97-103 s by ultrasonic shot peening equipment with power of 1800 W under conditions that the amplitude is 30 mu m and the frequency is 20 KHz, or the titanium alloy is treated for 97-103 s by the ultrasonic shot peening equipment with power of 2200 W under conditions that the amplitude is 30 mu m and the frequency is 20 KHz; the induction heating oxidation treatment is performed at follows: the titanium alloy after ultrasonic shot peening treatment is subjected to supersonic frequency induction heating for 20-35 s. The nanostructured bioactive oxide film prepared with the method can remarkably improve the bioactivity, biocompatibility and cell responsiveness of titanium and the titanium alloy implanted in vivo.
