摘要
The silane composite film formed on electrogalvanized steel sheet by silane film with ZrO2 improve the corrosion resistance. The surface morphology, the structure and composition as well as the corrosion resistance of the prepared silane composite fihn were investigated by SEM, AFM, XPS and electrochemical test. The experimental results showed that the structure of the silane composite film was composed of Si-O-Si three-dimensional network doped with ZrO2 showing excellent corrosion resistance, because the structure of this kind of composite film has much less micropore which improves the uniform and density of the silane film.
