摘要：

To enhance the bonding between hydroxyapatite (HA) coating and titanium alloy substrate, HA/TiO2 composite coatings have been fabricated via plasma spraying. Bonding strength evaluation, simulated body fluid tests, and cell culture in vitro were carried out to characterize the composite coatings. The results obtained showed that the addition of TiO2 to HA coating improved the bonding strength of the coating significantly. After being immersed in simulated body fluid (SBF) for a period, the surfaces of HA/TiO2 composite coatings were completely covered by carbonate-containing apatite, which indicated that the coatings possess good bioactivity. The in vitro cell culture indicated good cytocompatibility for HA/TiO2 composite coatings.
