摘　　要：含氟羟基磷灰石(FHA,Ca10(PO4)6(OH2-xFx),0<x<2)涂层由于比羟基磷灰石(Ca10(PO4)6-(OH)2,HA)涂层的溶解度低、热膨胀系数小且生物活性好在临床医学中有着更加广泛的应用前景。介绍了FHA的结构特点、FHA涂层的制备工艺,并重点陈述了溶胶-凝胶技术在制备FHA涂层中的应用。最后在综述国内外研究进展的基础上,提出了目前研究中存在的不足,并展望了FHA涂层今后的研究和发展趋势。Fluor-hydroxyapatite（FHA, Ca10（PO4）6（OH2-xFx）, 0〈X〈2） coating has a more promising application future due to its smaller solubility, smaller thermal expansion coeffient and better bioactivity than hydroxyapatite （Ca10（PO4）6（OH）2, HA） coating. The characteristic and structure of FHA, preparing methods of FHA coating are introduced in this work. The application of sol-gel technology in preparing FHA coating is emphasized. On the base of research progress at home and abroad, the deficiency in present research and the development of FHA coating are stated.
