Abstract:研究了 Ti、Ti6Al4V 和 Ti6Al7Nb 3种钛基材料在喷砂酸蚀处理后成骨细胞在其表面生长的生物活性。通过 Al2 O 3喷砂和盐酸、硫酸混合物酸蚀的表面改性方法,在 Ti、Ti6Al4V 和 Ti6Al7Nb3种钛基材料表面进行喷砂酸蚀处理,通过 SEM 观察样品的表面形貌,样品的表面呈现出微米级多孔形貌；将样品浸入模拟体液(simulated body fluid,SBF)中浸泡7,14和21 d 后通过 SEM、X 射线衍射仪(XRD)分析样品表面沉积物的形貌、物相,样品浸入 SBF 14 d 后, Ti6Al7Nb 表面最先观察到表面覆盖的羟基磷灰石涂层；样品浸入 SBF 21 d 后,Ti、Ti6Al4V 和 Ti6Al7Nb表面都观察到羟基磷灰石涂层。羟基磷灰石涂层有利于促进钛基植入体与体内骨组织的骨结合,喷砂酸蚀处理的 Ti6Al7Nb 表现出良好的生物活性。
