The restriction ban of Cr(VI) based treatment to enhance corrosion resistance of Zn and Zn-alloy coatings requires the development of an environmental friendly alternative process. This study is therefore focused into the synthesis of new treatments based on thin cerium oxide (ceria) films through a cathodic electrodeposition (CELD) process. The surface finishing of the Zn substrates, the electrolyte composition and the deposition parameters are systematically studied to obtain uniform thin ceria layers of diverse microstructures and compositions. Among them, the most homogeneous deposits will be immersed in a stirred and aerated 0.5 mol.L-1 NaCl solution in order to examine the protective ability of these thin cerium-based layers through electrochemical measurements.
