Formation of Titania Nanowires and Nanorods on Ti-6Al-4V Alloy Using Electrochemical Anodization

The formation of titania (TiO 2 ) nanowires and nanorods by various methods has been reported in the past. The current work, for the first time, describes the formation of TiO 2 nanowires and nanorods by using the electrochemical anodization method in 0.5 wt% hydrogen fluoride (HF) based aqueous electrolyte on Ti-6Al-4V alloy. Likewise, the TiO 2 nanotubes were grown on a titanium plate. The anodization voltage was varied, while temperature and time, were kept constant. The morphological and crystallographic characterization of the samples was performed.
