摘　　要：采用电泳沉积的方法在钛板表面制备了碳纳米管/羟基磷灰石复合涂层。XRD研究发现,复合涂层的成分主要是羟基磷灰石和碳纳米管;IR研究发现,复合涂层中含有羟基、磷酸根等官能团;SEM研究发现,复合涂层均匀致密,碳纳米管与羟基磷灰石颗粒混合均匀,且碳纳米管的表面已被1层羟基磷灰石薄膜均匀包覆。随着碳纳米管含量从20%增加到40%,复合涂层的致密度逐渐提高,其表面质量逐渐改善。The composite coating of CNTs/HAp has been prepared on a titanium substrate by the method of electrophoretic deposition technique.The results of XRD indicated that after sintering at 800℃for 2h in argon the main component of the composite coating is hydroxyapatite and carbon nano-tube.Micrograph of composite coating expressed that the composite coating is symmetrical and compact.CNTs was dispered in hydroxyapatite particles symmetrical and CNTs was coated uniformity by hydroxyapatite.With the content of carbon nanotube increased from 20 percent to 50 percent the density of the composite coating increased gradually and the surface quality improved gradually.
