| 中文摘要: |
| 采用正交设计法，获得了在环保型电解液中，钛合金经微弧氧化，其表面生长出生物活性陶瓷层的最优工艺，即：镁盐5g/L，硅酸盐40g/L，添加剂Sg/L，氧化电流密度l65mA／cm2，溶液温度35℃。当氧化时间为30min时，可获得6~lOμm的灰色光滑氧化膜。采用X衍射、扫描电镜研究氧化膜的结构、形貌，结果表明：钛表面氧化膜层含有大量锐钛矿相和少量钛酸镁相，表现出陶瓷性质，氧化膜层表面均匀分布大量微孔，孔径均匀，使得膜层有一定的粗糙度。钛氧化膜对仿生液的浸润性优于钛合金基体，氧化膜表面在过饱和磷灰石溶液中很容易生成磷灰石，具有生物活性。 |

| The optimum technique of micro-arc oxidiation for preparing biological activity ceramic film on titanium m an environment-friendly electrolyte was confirmed by orthogonal design. The result shows that the optimum condition of micro-arc oxidation process is as follows: 5g/L of magnecate, 40g/L of silicate, 5g/L of additive, 165 mA/cm2 for oxidation current density, 35 0C for solution temperature and it can obtain 6 ~ lOμm grey and smooth coating for 30 min oxidation. The coating contains abundant anatase and a little magnesium titanate, and exhibites ceramics performance. A large number of porous with uinform diameter distributes throughout the coating, which exhibites a certain extent coarseness. The oxidation film has better hydrophilicity than titanium matrix in the bionic solution. Apatite with biological activity can form on the oxidation film when the oxidation film is soaked in a saturated solution of calcium and phosphorus. |
