Abstract: This paper dealt with plasma-sprayed hydroxyapatite (HA) coatings on carbon/carbon composites(C/C)and the implantation was carried out in rabbits. Ninety days after the implantation, we found that such materials were favorable for health and no cytotoxic effects were discovered. The histological observation of osteogenic response of HA-coatedC/Cshowed that the osteoplaque had scansorially grown along the surface of the HA coatings and the pureC/Csurface had no obvious change. All these results indicate that as a potential bone-repairing material, the surface properties of theC/Chas been changed by preparing the HA coatings. Also the new materials may be preferably feasible of clinical application.
