Abstract
Biocompatible layers of hydroxyapatite and fluorhydroxyapatite were grown o n Ti substrates by means of dip-coating into sol-gel. In order to improve t he adhesion of apatite-based coatings, the substrates were a priori covered with calcium titanate. Therefore, the hydroxyapatite, fluorhydroxyapatite and CaTiO3 coatings were produced and analysed. The chemical composition of the coatings (CaTiO3, CaTiO3 + hydroxyapatite, and CaTiO3 + fluorhydroxyap atite) was studied by using X-ray photoelectron spectroscopy (XPS). The dat a of quantitative XPS analysis displayed the different features (cleanness, homogeneity, etc.) of CaTiO3, hydroxyapatite, and fluorhydroxyapatite film s after the growth and after the treatment in vitro.
