| 摘 要： | 采用沉淀法制备了F掺杂HA的FHA(Ca_(10)(PO_4)_6(OH)F)粉末,并通过电泳沉积在钛合金(Ti6Al4V)表面制备了FHA涂层。通过X射线衍射(XRD),扫描电镜(SEM),能谱仪(EDS)研究了基体预处理方式对涂层形貌和结合力的影响,并且研究了涂层的生物活性。结果表明:酸处理后涂层表面有微裂纹存在,酸处理+碱处理后的涂层表面无裂纹并具有更高的结合强度;FHA涂层浸泡后表面形成缺钙类骨磷灰石,成花瓣状生长,长度为几百纳米,具有优良的生物活性。

| Abstract: | FHA(Ca_(10)(PO_4)_6(OH)F) powder of F doping Ca_(10)(PO_4)_6OH)_2(HA) was synthesized by the precipitation method,and the FHA coating was prepared on the surface of the titanium alloy(Ti6AI4V) by electrophoretic deposition.XRD,SEM and EDS were used to investigate the influences of the substrate pretreatments on the coating morphology and binding force of the coatings,and the bioactivity of the coatings was also investigated.The results show that there are microcracks on the surface of the coatings pretreate... |
