Abstract

Hydroxyapatite/titania composite material was coated onto a titanium (pure Ti) substrate by sol-gel method. The hydroxyapatite (HA) and titania (TiO ₂ ) sol were made from precursor and mixed together. The insertion of TiO ₂ enhanced the chemical affinity and the physical consistency between HA and Ti substrate. The HA/TiO ₂ composite coating adhered tightly to the Ti substrate. Owing to the insertion of TiO ₂ , the crystallinity of HA has been delayed. The specimens with HA/TiO ₂ composite coatings were soaked into SBF, and displayed good bone-like apatite forming ability. The bioactivity of the composite HA coatings were tested in vitro by cell culture. Crown
