Abstract
A powder for coating the surface of a titanium metal is obtained by mixing compounds as raw materials for CaO, TiO.sub.2, and P.sub.2 O.sub.5 with a small amount of a Na.sub.2 O-containing compound, fusing the resultant mixture, and solidifying and pulverizing the fused mixture. A coating of a calcium phosphate compound adhering with great fastness to the surface of the titanium metal is formed by preparing an aqueous slurry containing the powder mentioned above, applying the aqueous slurry to the surface of the titanium metal, and heat-treating the coated titanium metal.
