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.
