通过声电沉积工艺在炭/炭复合材料表面制备钙磷生物活性涂层,采用扫描电镜、X射线能谱仪、X射线衍射仪、红外光谱等方法研究了氟化钠处理前后钙磷生物活性涂层的形貌、结构和组成.实验结果表明:氟化钠能促进磷酸三钙转化为含氟羟基磷灰石(FHA),并提高涂层结晶度;经氟化钠处理后,羟基磷灰石(HA)的(112)、(300)衍射峰明显增强,涂层是HA和FHA的混合物.氟化钠处理前后涂层表面形貌均为片状晶体,但处理后其颗粒尺寸增大;氟化钠处理后涂层与基体的结合强度略有增强,结合强度可达4.08 MPa,涂层氟的含量为4.59 wt%.分析了炭/炭复合材料表面HA转变为FHA的反应机制.采用氟化处理HA制备FHA涂层时,应加入磷酸盐保持整个反应过程的pH值不变.
