Notes:
This research is aimed at the development and characterization of a novel bioceramic coatingon the surface of pure titanium. Nano-TiO2/HA composite bioceramic coating was designed anddeveloped on the surfaces of pure titanium discs by sol-gel route. The TiO2 anatase bioceramic coatingwas employed as the inner layer, which could adhere tightly to the titanium substrate. The porous HAbioceramic coating was employed as the outer layer, which has higher solubility and better short termbioactivity. Conventional HA coatings and commercially pure titanium (cpTi) were taken as control.XRD and SEM were employed to characterize the crystallization, surface morphology and thickness ofthe coatings. The bioactivities of the coatings were evaluated by the in vitro osteoblasts culture. Resultsshow the nano-TiO2/HA composite bioceramic coating has good crystallization and homogeneous,nano-scale surface morphology. And it adheres tightly to the substrate. The in vitro osteoblasts cultureexhibits satisfactory bioactivity
