Abstract
The aim of the present study was to characterize sol-gel derived titania coatings prepared by dipping. The surface characterization was carried out using X-ray photoelectron spectroscopy (XPS) and time of flight secondary ion mass spectrometry (ToF SIMS), combined with X-ray diffraction (XRD) and thermal analysis. Sol-gel derived titania surfaces mimicked the surface chemistry of the natural oxide layer found on commercial titanium implants. These surfaces could be used to develop an in vitro model of the osseointegration process. Similar analytical techniques were applied to apatite-like coatings and preliminary results suggest that hydroxyapatite coatings can be produced from a sol-gel route.
