Patent number: 6153266Abstract: The present invention provides a method for producing a calcium phosphate coating film on the surface of a substrate, even a substrate which has poor heat resistance. The method comprises the steps of soaking a substrate in a first solution containing phosphate ions, inter alia, aqueous solutions of a basic phosphate salt such as Na.sub.3 PO.sub.4 or Na.sub.2 HPO.sub.4 ; removing the substrate and drying it; and soaking the substrate in a second solution (aqueous solution) containing calcium ions, to thereby obtain a coating film comprising hydroxyapatite or a mixture containing hydroxyapatite and a hydroxyapatite precursor. The substrate removed from the second solution may be soaked in a third solution (aqueous solution) containing an apatite component at a substantially saturated or supersaturated concentration, to thereby form a hydroxyapatite coating film. There may be used substrates formed of metals, ceramics, organic polymer materials, etc.Type: GrantFiled: December 7, 1998Date of Patent: November 28, 2000Assignees: Japan as represented by Director General Agency of Industrial Science and Technology, NGK Spark Plug Co., Ltd.Inventors: Yoshiyuki Yokogawa, Tetsuya Kameyama, Yukari Kawamoto, Kaori Nishizawa, Fukue Nagata, Kohji Okada, Hiroshi Sumi
