Effects on surface microstructure and mechanical property of pure titanium (TA1) for implant treated by anodic oxidation were investigated. We found that the oxide film with a certain uniform and compact color could be achieved by anodic oxidation method. However, with the increasing of oxidizing voltage and time, the oxide film will be dissolved at local area. The oxygen content of oxide film and the hydrogen content of matrix titanium will be raised, and will also be increased. In fact, hydrogen could be diffused into matrix titanium. With the increase of hydrogen content of matrix titanium and sigmas/sigmab, there appear the possible results of plastic deformation and the fracture of implant.
研究了阳极氧化处理对植入用纯钛（TA1）表面微观结构和力学性能的影响。我们发现，通过阳极氧化法可以获得具有一定均匀且致密颜色的氧化膜。然而，随着氧化电压和时间的增加，氧化膜会在局部区域溶解。氧化膜的氧含量和基体钛的氢含量会升高，并且也会增加。实际上，氢会扩散到基体钛中。随着基体钛氢含量和σs/σb的增加，出现植入物塑性变形和断裂的可能结果。
