| 摘 要： | 为了在医用化学气相渗透工艺(CVI)C/C复合材料表面制备生物活性钙磷涂层,用阴极声电化学工艺处理CVIC/C复合材料,再将试样浸泡于过饱和钙磷溶液中,使其诱导钙磷晶体生长.XPS研究表明,经声电工艺处理后,CVIC/C复合材料表面发生了改性;SEM,XRD和FTIR研究表明,在过饱和钙磷溶液中,未经声电化学处理的CVIC/C复合材料不具有诱导钙磷晶体生长的功能,而改性的CVIC/C表面能够诱导钙磷晶体生长,形成片状五水磷酸八钙(OCP)涂层.同时讨论了OCP沉积的形成机理.

| Abstract: | In order to make biomimetic calcium phosphate on the surface of bionert CVI C/C composite, a novel method was put forward with which CVI C/C composite is treated by cathode sonoelectrochemical technology, then the as-treated CVI C/C is immersed in a supersaturated calcium phosphate solution(SCPS) to induce the growth of calcium phosphate. XPS, XRD, SEM and FTIR analysis results show that octacalcium phosphate [Ca8 (HPO4)2(PO4)4·5H2O] coatings can grow on the surface of CVI C/C, while no calcium phosphate will be gotten on CVI C/C. The deposition and formation mechanism of OCP coatings was also discussed. |
