Ti40 Zr10 Cu36 Pd14金属玻璃具有较好的玻璃化形成能力和可靠的生物力学性能,但生物活性较差.采用溶胶凝胶法在Ti40 Zr10 Cu36 Pd14金属玻璃表面构建TiO2涂层,并进行水热处理使其具有锐钛矿结构;随后又在模拟体液(SBF)中进行仿生生长实验.采用扫描电子显微镜(SEM)、X射线衍射仪(XRD)和激光显微拉曼光谱仪(Ra-man)等观察和分析涂层表面形貌及物相组成.结果表明,TiO2涂层可改善Th0Zr10Cu36Pd14金属玻璃试样表面生物活性;在模拟体液中浸泡7天后,覆盖TiO2涂层的金属玻璃可快速诱导磷灰石沉积,在金属玻璃基体表面形成HA/TiO2复合涂层.
