Synthesis and Characterization of Titania Nanotubes on Titanium alloy IMI 834 by Electrochemical Anodization Process

Electrochemical anodization offers large surface area architecture with precisely controllable nanoscale features in the fabrication of highly ordered vertically oriented TiO2 nanotube arrays. Abundant research work has been accomplished on pure titanium and their alloys like Ti 64, TiNb, TiAl etc. Yet, no work has been proclaimed on Titanium alloy IMI 834. In the present investigation, the synthesis of highly ordered Titania nanotubes by electrochemical anodization of the alloy IMI 834 in different electrolytes was carried out. The synthesized nanotubes were characterized by Scanning Electron Microscope (SEM), Field Emission Scanning Electron Microscope (FESEM), Electron Dispersive Spectroscopy (EDS) and X-ray diffraction (XRD) techniques. The results spectacles that the size and morphology rely on the electrolyte composition. Among the electrolytes, the combination of 0.5wt% HF and 1M phosphoric acid is more suitable in producing ordered Titania nanotubes on titanium alloy IMI 834.
