| 摘 要： | 研究阳极氧化工艺对纯钛TA1植入体表面氧化膜的表面形貌及力学性能的影响.结果表明:阳极氧化工艺可以在TA1基体表面形成不同颜色的均匀、致密的氧化膜.但是,随着阳极氧化电压升高、时间延长,膜层出现部分溶解现象,膜层中氧含量增加,基体中氢含量升高,材料的屈强比(σs/σb)增加,说明,氢元素向TA1基体扩散,导致材料的屈强比增大,不利于纯钛植入体塑性形变,植入人体一定时间后,有诱发材料疲劳断裂的可能性.

| Abstract: | 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 ... |
