Abstract :
Self aligned TiO2 nanotube arrays were synthesized on Ti foils by electrochemical anodization technique. The qualitative mechanistic aspect of nanotube formation is discussed based on the results of potentiostatic transient measurements. The structural and morphological stability of the nanotube arrays synthesized were investigated by annealing the anodized foils at various temperatures and then carrying out the XRD and FESEM analysis. The phase transformation and crystallization of nanotubes are discussed briefly.
