摘要: Abstract In this study, photoelectrochemical analysis of bioactive material coated nanotubular surface Ti–30Nb–xZr alloy has been investigated using a potentiostat and Xenon lamp. Ternary Ti–30Nb–xZr(x = 3, 15 wt.%) alloys were prepared, nanotube was formed in 1 M H3PO4 + NaF(0.8 wt.%). Hydroxyapatite (HA) on by electron-beam physical vapor deposition (EB-PVD) method. The characteristics behavior FE-SEM, EDS, XRD potentiostat. microstructures the Ti–30Nb–3Zr Ti–30Nb–15Zr showed an equiaxed grain structure with needle-like α phase β grains. large nanotubes surrounded smaller diameter highly ordered alloy. HA irregular flake-like particles (211) (112) crystalline planes. UV-irradiated alloy, current density passive region higher than that non-UV-irradiated whereas for difference between not significant. Rp value coated/nanotube under UV-irradiation other surface. angle close to 60–70°. study suggested photofunctionalization reaction strongly depends oxide surface, crystallinity hydroxyapatite alloying elements.
