✦ Synopsis

Abstract

Titanium surfaces were treated by exposing them to a beam of sodium ions. Sodium titanate was shown to be incorporated within the oxidic titanium surface. The ion‐implanted surfaces were examined for their reactivity by immersion in a simulated body fluid, which showed the formation of surface‐bound hydroxyapatite. The surface was characterized by X‐ray diffraction, Fourier transform infrared spectroscopy, X‐ray photoelectron spectroscopy, and optical and electron microscopy. The surface hydroxyl concentration was determined using the nuclear reaction ^1^H(^15^N, αγ)^12^C. Surface‐related parameters that may affect hydroxyapatite nucleation are discussed in terms of the electrical double layer. © 2001 Wiley Periodicals, Inc. J Biomed Mater Res 59: 716–724, 2002

## Abstract A new hydrocoating method (the thermal substrate method) has been proposed for coating calcium phosphates, such as hydroxyapatite, onto titanium substrates in an aqueous solution. The influences of several solution properties on the thermal substrate method were examined. The solutions
