In order to understand the rule of TiO2 in the deactivation mechanism of an active RuO2-TiO2 coating, an additional TiO2 laver was introduced in the support\coating interphase of regular Ti//[RuO2-TiO2] anode in one case and on the surface of the coating in the other. The electrochemical behavior of these, with TiO2 enriched, anodes was compared with the behavior of anodes with regular RuO2-TiO2 coatings. which were subjected to an accelerated stability test. A high-frequency semicircle in the complex plane plot, obtained by electrochemical impedance spectroscopy, for a regular RuO2-TiO2 coating corresponds to TiO2 enrichment in the coating as a consequence of anode corrosion. In the case of the coatings with additional TiO2 layers, a high-frequency semicircle was not observed The additional TiO2 layers increase the coating overall resistance and influence the coating impedance behavior at low frequencies. Similar equivalent electrical circuits were used to analyze the impedance behavi...or of coatings having an additional TO, layer at different position within RuO2-TiO2 coating.
