Résumé : Thin oxide films are grown electrochemically on commercially pure titanium substrates. Constant potential (potentiostatic), constant current (galvanostatic) and initial constant current followed by constant potential (combined) growth modes are studied. The structure, the composition, the thickness, the electrochemical and the semiconducting properties of the oxide films are considerably influenced by the growth mode even if the final anodizing potential has a constant value. © 1994.
