Microstructure and optical properties of TiO$_2$- and HA-coated Ti6Al7Nb alloy by sol–gel method
NIHAT TOSUN SALEH ZAKAR KURMI GUL TOSUN
In this study, the combination of titanium dioxide (TiO$_2$) and/or hydroxyapatite (HA) coatings on Ti6Al7Nb titanium alloy to be used as an implant was performed in different solution retention times by the sol–gel dip-coatingmethod and the characterization and optical properties of these coatings were investigated. Two different coatings were made on the substrate, the first group of samples was first coated with TiO$_2$ and then with HA, while the second group of samples was coated with TiO$_2$ alone. Before sol–gel coating, the samples were rinsed in distilled water and dried at 200$^{\circ}$Cfor 2 h. The samples were immersed perpendicular to the coating solution. Thin films were obtained at a draw rate of 2 mm s$^{-1}$. Microstructure investigations of the prepared coatings were examined under optical and scanning electronmicroscopes, while solid-state elemental fractions were determined by energy-dispersive X-ray spectroscopy analysis. Fourier-transform infrared spectroscopy analysis was performed to determine the functional groups placed on the surfaceof the material. The optical properties of the material were determined by UV analysis.
