| Abstract: | The aerosol-gel process has been assayed for the deposition of calcium phosphate (CaP) coatings. The deposition conditions have been preliminarily studied in order to obtain polycrystalline hydroxyapatite (HAP) coatings. The evolution of composition, structure and morphology was monitored by FTIR, XRD and SEM techniques as a function of the sintering temperature. HAP coatings deposited on TiAlV substrates were further characterized by Auger and indentation techniques in order to measure their quantitative composition and adhesive strength, respectively. The results corroborate the high quality of aerosol-gel derived HAP coatings. |
