Titanium Dioxide (TiO,) films by anodic oxidation in phosphoric acid
Anodic oxidation is an electrochemical method for the production of an oxide film on a metallic substrate. It involves the application of an electrical bias at relatively low currents while the substrate is immersed in an acid bath. The films can be very dense and stable, with a variety of microstru...

| description |
Anodic oxidation is an electrochemical method for the production of an oxide film on a
metallic substrate. It involves the application of an electrical bias at relatively low currents while the
substrate is immersed in an acid bath. The films can be very dense and stable, with a variety of
microstructural characteristics. In the present work, flms of the anatase polymorph of Ti02 were
formed on high-purity Ti foil (50 pm thickness) using phosphoric acid (0.3 A4 H3P04). Thc
conktions of oxidation involved the application of potentials (5 to 350 V) and current densities (5
to 60 m~.cm") for 10 m& at room temperature. The films were characterised using a digital
photography, laser Raman microspectroscopy, and field emission scanning electron microscopy.
The thicknesses of the oxide films on Ti were measured using a thin film analyser based on optical
spectroscopy principles. The colours, thicknesses, and microstructures of the films depended
strongly on the applied voltage and current density. At bias more than 15 V, single-phase anatase
was observed to form on Ti at low (5 m ~ . c m -a~nd) h igher (up to 60 m~.cm-')c urrent density. |
