Electrocoating of Titanium Nanoparticle and Investigation of its Characters

Abstract

Titanium oxide nanotubes were fabricated by anodic oxidation of a pure titanium sheet in 1.5 M H₂SO₄, 0.3 M H₃PO₄ and 0.3 M H₂O₂ mixture solution. The morphology of Titanium oxide nanotubes surface were investigated by scanning electron microscope (SEM). These tubes are well aligned and organized into high-density uniform arrays. While the tops of the tubes are open, the bottoms of the tubes are closed, forming a barrier layer structure similar to that of porous alumina. The average tube diameter, ranging in size from 40 to 70 nm.
