The synthesis of TiO2 nanotubular coatings was carried out through the anodic oxidation process, using rings as substrate from a tube of commercial grade 2 titanium (TiG2) with longitudinal welding. To obtain the nanostructures, rings were anodized at 40 V for 2 h using a solution of 0.27 M NH4F in ethylenglycol and 3,5 % v/v water, with cooling, as electrolyte. Micrographs obtained by scanning electron microscopy showed nanotubes with an internal diameter of 85 nm, wall thickness of 7 nm, and length of 5 μm. The diffractograms of the post-thermal treatment coatings indicated the presence of the anatase phase. Welding had no influence on the coating characteristics.
