Abstract: Two type of multilayer structures based on ZrO2 coatings deposited on TiO2 were applied on low carbon steel and their structure, composition and anticorrosion properties were evaluated in 5%NaCl salt medium. The phase composition, morphology and the elemental distribution of the coatings were investigated using X-ray diffraction analysis, Atomic Force Microscopy (AFM), Scanning Electron Microscopy (SEM) and energy dispersive X-ray analysis (EDX). The corrosion performance of the coatings was evaluated by potentiodynamic polarization measurements (PD). The zirconia/titania mixed oxide coating exhibited an enhanced corrosion resistance than those of the low carbon steel as indicĐ°ted by the reduced current density, probably due to the presence of amorphous structure on the layers and dense surface without visible cracks and pits (barrier effect).
Keywords: corrosion protection, dip coating, barrier properties, morphology
