Abstract: Electrochemical impedance spectroscopy (EIS) technique has been used to study the electrochemical behaviour and stability of thin oxide films formed on titanium in different acidic and neutral solutions. The effect of formation voltage, formation current density and passivation medium on the properties and stability of the anodic oxide films formed on titanium was also investigated. Titanium electrode showed high stability in perchloric acid and neutral salt solutions. The thickest anodic oxide films have been obtained at a formation voltage of 8V. The stability of the passive films is more affected by the passivation medium than the dissolution one.
