Abstract

Composites of hydroxyapatite (HA) granules implanted into the surface of a titanium alloy (Ti-4.5Al-3V-2Fe-2Mo) were successfully formed at a granule density of about 0.08 mg HA/mm² on titanium alloy disks 10 mm in diameter and 0.7 mm thick under the conditions of 1073 K, 10 min, 17 MPa. The entire material surface, with no damaged HA granules, became covered with proliferating human gingival epithelial (HGE-15) cells. This composite and the proposed method are expected to be useful for orthopaedic and dental implants such as stems, dental roots, and so on.
