Abstract

Thermally annealed structures of hydroxyapatite-TiO2-Ti prepared by high-frequency magnetron spraying have been studied before and after incubation in the 0.02 mol/l buffer solutions of KH2PO4-Na2HPO4 at pH 6.0, 7.0, and 8.0. Atomic force microscopy has revealed that the surface relief and mean roughness are not changed in the course of incubation. No sharp changes in the calcium to phosphorus ratio have been observed according to local X-Ray spectral microanalysis. The stability of hydroxyapatite-TiO2-Ti towards buffer solutions has been confirmed by X-Ray powder diffraction studies.
