✦ Synopsis

Abstract

In previous investigations, a simple method, precalcification, was developed for bioactivating titanium. After a titanium sample was precalcified in a boiling saturated Ca(OH)~2~ solution and then immersed in a calcium phosphate supersaturated solution, an apatite coating rapidly precipitated onto its surface. In the present study, heat‐treatment in water vapor was carried out prior to precalcification. Heat‐treatment in water vapor stimulated the chemical reaction between titanium, calcium, and phosphate. Coating properties were improved, and the bond strength of the coating to substrate was enhanced. © 2001 Wiley Periodicals, Inc. J Biomed Mater Res 59: 12–17, 2002
