Fabrication of Bioactive Apatite Nuclei-Precipitated Composites
Many micropores were formed on the surface of a Ti-15Mo-5Zr-3Al alloy plate and a polyethylene terephthalate (PET) plate by sandblasting, Apatite Nuclei were precipitated in the pores, then bioactive Apatite Nuclei-precipitated composites were fabricated. In order to examine the bioactivity, the composites were soaked in SBF and it was observed that hydroxyapatite was induced on the whole surface within 1 d. The hydroxyapatite layer possessed high adhesive strength to the plate due to a mechanical interlocking effect between hydroxyapatite in the micropores and the plate.
