Popis: Hydroxyapatite (HAp) has been successfully coated on etched titanium substrates by hydrothermal method using solutions of Ca(NO3)2.4H2O, NH4H2PO4 at 200 oC for 12 h. Results obtained from measurements on the modern physical methods of FE-SEM and XRD showedhat the structure of HAp has a regular hexagonal morphology belonging to the space group P63/m. The degree of HAp nucleation and nucleation development on the un-etched titanium plates was lower than that on the etched titanium plates. In vitro bioactivity of HAp-coated titanium testing using SBF solution showed prospective results. Keywords: Hydroxyapatite (HAp), Hydrothermal method, etched, titanium.
