摘要
Abstract
The surface morphology, element compositions and electrochemistry performance of titanium salt film, silane film and titanium/silane composite films were tested. The salt spray test resistance and corrosion resistance of those films were compared to ordinary chromate salt conversion film. Result shows the corrosion current density of passivated galvanized sheet is reduced, polarization resistance and electrochemical impedance are greatly improved. The corrosion resistance of composite film is close to the common chromic acid passivation film. SEM and EIS analysis shows the silane coating is only a protective overlay.关键词
