| 摘 要： | 以Ca(NO3)2×4H2O和P2O5乙醇溶液为先驱体，六氟磷酸(HPF6)为氟引入剂，采用溶胶-凝胶法在钛合金基板上制备含氟羟基磷灰石涂层. 获得的涂层晶粒尺寸为120~150 nm. 实验结果表明，加入HPF6后形成的含氟磷灰石涂层在模拟体液中有良好的生物活性特性，在柠檬酸改性的磷酸缓冲溶液中表现出较好的稳定性.

| Abstract: | A fluorapatite/hydroxyapatite coating on Ti6Al4V substrate was prepared by sol-gel technique using Ca(NO3)24H2O, P2O5, hexafluorophosporic acid (HPF6) as the starting materials and the fluorine-introducing reagent. The results show that the sol-gel derived fluorapatite/hydroxyapatite coating has a good in vitro behavior in the simulated body fluid, and has a better stability in the citric acid modified phosphate buffer solution than hydroxyapatite coating. The sol-gel derived coatings are composed of nano apatite crystallites. |
