摘要
介绍采用阳极氧化方法在纯钛表面成功制备了TiO2薄膜。采用SEM-EDAX仪研究薄膜表面形貌及化学成分,并对钛种植体阳极氧化后在37℃的SBF模拟人体体液中沉积羟基磷灰石的能力进行评价。结果表明,在该实验条件下,钛种植体经阳极氧化后表面呈显微粗糙状态,为蜂窝状微孔,微孔彼此连通,孔隙分布均匀,孔径约为1～2μm,是典型的阳极氧化形貌特征。薄膜经碱处理后,在SBF溶液中沉积羟基磷灰石能力得到明显提高。
This paper introduces how TiO2 film was prepared on pure titanium by anodic oxidation. Surface morphology and composition of the oxide film were analyzed by SEM coupled with EDAX. The deposition ability of hydroxyapatite of the anodized titanium in simulated body fluid （SBF） at 37℃ was evaluated. The results indicated that the oxide film was rough and honeycomb holes,connecting with each other,could be found on the surface. The holes with the diameter of 1～2μm were distributed uniformly,which was typical for anodic oxidation. After alkaline treatment,hydroxyapatite deposition on the oxidized specimens in SBF was improved significantly.
