Titanium is used for many applications, ranging from
chemical, biomedical, and decorative. Its versatility is due to its excellent mechanical
properties, high corrosion resistance and biocompatibility. Moreover, its oxides, grown by
anodising techniques, can have different colourations, which make them useful for applications
related to art and architecture; in their crystalline form, they show excellent photochemical
properties, which are widely used in chemical synthesis and in the cleansing of pollutants. The
aim of this work is to characterise the titanium dioxide films, grown anodically in sulphuric
acid 0.5 M at three different anodising potentials, by potentiodynamic polarisation and
electrochemical impedance spectroscopy (EIS). When comparing the obtained oxide films, a
progressive increment in their crystallinity and electrical resistance was observed with the
increase of the anodising potential.
