摘要：
The aim of this study was to investigate the effects of ceria doping on corrosion resistance of amorphous silica-titania coating. The microstructural and phase properties of titania-silica and titania-silica-Ceria composite films were investigated by SEM, EDAX and XRD. Potentiodynamic polarization and EIS spectroscopy have been used to study the corrosion behavior of composite coating in 3.5% NaCl solution. Results showed that by cerium doping into silica-titania coating as an inhibitor, the corrosion resistance of the film increased. In addition this study revealed that cerium doping enhanced pitting resistance of the coating. (C) 2009 Elsevier B.V. All rights reserved.
