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

Abstract

The formation of titania (TiO2) nanowires and nanorods by various methods has been reported in the past. The current work, for the first time, describes the formation of TiO2 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 TiO2 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.
