Abstract

In this study, we investigated the oxidation process of titanium in two different electrolytic solutions in order to understand the effect of the electrolyte on the microsized tubular TiO2 formation and their structure. In the first set of experiments, we used 0.5% HF electrolyte by applying 23 V for 50 min. The second set of experiments was performed using glycerol electrolyte with 0.27 M NH4F and 1.5% H2O under 40 V for 19 h. Both experiments were performed at room temperature. After the anodizing process, the samples were annealed at 550 °C in O2 atmosphere. In both electrolytic conditions well-ordered microsized tubular TiO2 were obtained. The morphologies, structures, and microsized tubular TiO2 array films were characterized by FE-SEM, EDS, and XRD.
