GALVIS, Oscar et al. Fabrication of porous anodic layers on titanium by plasma electrolytic oxidation. Rev. ion [online]. 2012, vol.25, n.spe, pp.39-43. ISSN 0120-100X.

Anodic coatings were obtained on Ti through plasma electrolytic oxidation in sulfuric acid (H2SO4) solutions containing phosphoric acid (H3PO4) as an additive. The coatings corrosion behavior was evaluated by means of Electrochemical Impedance Spectroscopy (EIS) in Simulated Body Fluid solution (SBF). Characterization of the coatings was made using SEM/EDS and Raman spectroscopy, It allowed to observe great influence in its morphology and composition due to phosphoric acid content into the coatings.

Keywords : titanium oxides; plasma electrolytic oxidation; anodic coatings; SBF; biomaterials.
