ABSTRACT:
A titanium composite material is disclosed which comprises a titanium or titanium alloy substrate, a base layer formed thereon of a calcium phosphate compound resulting from calcination of a hydrochloric or nitric acid aqueous solution of the calcium phosphate compound, and a covering layer thereon of a calcium phosphate compound formed by sintering a suspension of the calcium phosphate compound applied to the base layer. The composite material is useful as a biological implant. It is produced by activating the surface of the substrate, forming the base layer by calcining the solution coated on the substrate and then forming the covering layer by sintering the suspension coated on the base layer. The covering layer may be hydrothermally treated to increase its crystallinity.
