Abstract

The coatings of hydroxyapatite are widely used for orthopaedic and dental prostheses, Nevertheless, their chemical, biological and mechanical properties still can be improved by the development of new preparation technologies. Here we report a surface characterization of hydroxyapatite coatings prepared by different deposition techniques. The layers of hydroxyapatite are grown on commercial titanium substrates by using sol-gel and electrodeposition techniques, The biocompatibility of the samples is tested upon in vitrotreatment as a function of the exposure time, Surface chemical compositionand morphology of the coatings are studied by means of x-ray photoelectronspectroscopy (XPS), scanning Auger microscopy (SAM) and scanning electron microscopy (SEM), Quantitative XPS analysis and surface chemical and physical images reveal different features (cleanness, homogeneity, roughness) of the coatings and different surface modifications induced by the interactionwith osteoblast cells.
