采用电化学腐蚀的方法在Ti基金属玻璃表面构建多孔粗糙结构,改善其表面活性,并通过模拟人体溶液(SBF)中的仿生矿化生长的方法在此多孔粗糙表面上成功制备了类骨磷灰石层.利用扫描电子显微镜(SEM)、X射线衍射分析(XRD)、X射线光电子能谱(XPS)等分析手段对电化学腐蚀和仿生生长后的表面形貌、物相组成、成分价态等进行表征.结果表明,当HNO3浓度为10%,阳极电压为2V,处理温度60℃下可以在Ti40Zr10Cu36Pd14金属玻璃表面建立均匀表面多孔结构;具有这种多孔表面的金属玻璃经过热碱处理可以在模拟人体溶液(SBF)中快速沉积类骨磷灰石层;分析表明类骨磷灰石的主要组成是羟基磷灰石(HA).
