ABSTRACT:
A process for producing a calcium phosphate compound coated composite material is disclosed, wherein a coating layer of a calcium phosphate compound is formed on the surface of a metal substrate by coating the surface of said metal substrate with an aqueous solution of nitric acid having hydroxyapatite dissolved therein, and then firing said coated substrate at a temperature of 300.degree. C. or more. The composite material is useful as implants (e.g., artificial bones, dentures, and dental roots) and cements therefor.
