摘要：

The aim of this paper is to evaluate the effects of titanium anodic oxidation in a sulphuric acid electrolyte on the crystallinity of the oxide layer and to adjust the process parameters, in order to maximize the TiO2 crystalline phase, specially for what concerns the anatase form. In particular, the relationship between anatase formation and anodization parameters, such as current density and applied potential, will be evidenced. From XRD analysis two opposite trends emerged: oxide conversion to anatase is promoted either by an increase in current density or by a decrease in sulphuric acid concentration.
