Abstract

为提高医用TC4钛合金表面熔覆羟基磷灰石（HA）涂层的植入稳定性和生物活性，采用激光熔覆方法制备出不同含硅量的CaP生物陶瓷涂层。利用扫描电子显微镜（SEM）和X射线衍射仪（XRD）表征了熔覆层组织形貌和物相组成。结果表明：添加SiO2（1wt.%、3wt.%）后形成Ca2SiO4相，熔覆层中部组织细化。通过电化学腐蚀和体外SBF浸泡实验研究了SiO2含量对涂层耐腐蚀性和生物活性的影响。电化学腐蚀结果表明：随着SiO2含量的增大，涂层表面腐蚀电流密度逐渐减小；体外SBF浸泡结果表明：添加SiO2可以加快涂层表面类骨磷灰石的形成，其中，添加SiO2为1wt.%时涂层表面类骨磷灰石呈均匀分布。因此，低含量SiO2可以提高生物陶瓷涂层的耐腐蚀性和生物活性。
