Abstract:
TiO2 and RuO2 have many applications in the field of photocataliysis, environmental protection, high charge storage capacity devices etc. Electro deposition offers advantages such as rigid control of film thickness, uniformity and deposition rate. Electro deposition of RuO2-TiO2 coatings on Ti substrates was performed via hydrolysis by electro generated based of TiCl4 and RuCl3 salts dissolved in mixed methyl alcohol-water solvent in presence of hydrogen peroxide for one, three and six layer. The obtained coatings have been heated in electric furnace at 500 ˚C. cathodic deposits were obtained at a constant current density of 20mA/Cm2 for 10min.
The micro-structure of coating was characterized using field Emission scanning electron microscopy (FESEM). In order to investigate, the crystalline phases of coating X-Ray analysis were carried out. Finally the electrochemical behavior of activated titanium anodes was investigated by polarization measurements in 0.5M NaCl solution in water in potential range of -1_3 mV/S. Results show that RuO2-TiO2 with six layers on Ti substrate is the useful coating. It means that by increasing the number of coatings the in-homogeneity and porosity on the surface disappears, crystal grains will be refined, and the homogeneous morphology will be formed.
