Abstract

Titanium/hydroxyapatite hybrid biomaterial is proposed to have both osteoconductivity and mechanical strength as alternative bone materials. The titanium/hydroxyapatite hybrid material was prepared by spark plasma sintering (SPS) method which is a suitable to sinter dense compacts at relatively low temperature in short time in vacuum, to obtain bending strength and suppress a compositional change for sintered materials. The three-point bending test showed the bending strength for the fabricated titan ium/hydroxyapatite hybrid materials were stronger than that for human bone. As hydroxyapatite content of the hybrid materials increased, the amount of hydroxyapatite forming on the surface of hybrid materials increased in the simulated body fluid (SBF) test. Titanium/hydroxyapatite hybrid materials with 4-8 wt. % of hydroxyapatite showed Vickers microhardness of higher than 4 GPa, bending strength higher than 400 MPa, and osteoconductivity. Because of these properties, titanium/hydroxyapatite hybrid material is expected to be an attractive candidate for biomaterials.
