Abstract In the present study, titania (TiO2) nanotube has been fabricated over the Ti6Al4V alloy in an organic electrolyte via anodization route. Synthesis of nanotube has been carried out in presence of ammonium fluoride (NH4F) salt with ethylene glycol and de-ionized water. The effect of anodization parameters on the size, shape and morphology of the pristine TiO2 nanotubes has been studied. In addition, the influences of specific field potential as well as higher electrolyte bath temperature have also been evaluated in view of its structure and surface nano-topography. Experiments were conducted at different applied potential (20 V, 25 V and 30 V) at room temperature, as well as at bath temperatures 30 °C, 45 °C and 55 °C at a potential of 20 V. The structure and morphology of the as-prepared nanostructures were studied by using XRD and FE-SEM. X-Ray diffraction spectra confirms the formation of crystalline anatase phase. For tissue engineering of hard tissue, contact angle analyzer has been utilized to understand the wettability of the nanotubes with different diameters in order to recognize their hydrophilic properties.
