Abstract: Titanium compound nanowire arrays were fabricated into the pores of anodic alumina membrane by electrodeposition under DC and pulsed current. Through scanning electron microscopy and cyclic voltammeter, the effects of deposition conditions such as the electronic signals and applied voltages on the quality of prepared nanowires were investigated. Dense Ti(Ⅳ) compound arrays were obtained by using pulsed eletrodeposition.

Key words: anodic alumina membrane, pulsed current, electrodeposition, nanowire arrays
