| Abstract: | High-frequency magnetron sputtering (HFMS) at various plasma powers has been applied to obtaining hydroxyapatite (HA) coating with amorphous and crystalline structure on VT1-0 titanium. The results concerning the influence of thermal treatment on the coating under isothermal holding for 1 h at 700–1000°C are presented. Structure, phase composition, topography and morphology of the formed hydroxyapatite coatings have been analyzed by X-ray phase analysis, scanning electron microscopy, energy-dispersive spectroscopy, atomic-force microscopy, and IR spectrometry. It is found that, depending on discharge power and temperature of isothermal annealing, molecular bonds are formed that are typical for HA accompanied by variations in phase and elemental compositions. |
