Photo-induced properties of anodic oxide films on Ti6Al4V

► Anodic oxides are prepared in a sulfuric acid electrolyte on Ti6Al4V. ► Anodic oxides are predominantly TiO2 with V2O5, VO2 and Al2O3. ► Fraction of V2O5, VO2 and Al2O3 decreases with sulfuric acid concentration. ► Low photo-induced characteristics observed are explained by the presence of Al2O3 and VOx.
