Electrochemical Impedance Spectroscopy Study of the Effect of Curing on Property of Vinyltriethoxysilane Films on Carbon Steel Surfaces
Silane treatment has been applied as a chromium free multi-metal surface treatment for its characteristics of corrosion protection. Silane film curing process is one of the most important variables, the effect of curing temperature and time on the corrosion resistance of vinyltriethoxysilane(VTES) film was studied combined with electrochemical impedance spectroscopy (EIS) and scanning electron microscope (SEM). The results showed that the curing temperature and time affect condensation of silanol groups Si-OH in silane films and forming intermediate layer at the silane film/substrate interface, and as a consequence influences the corrosion resistance of VTES films.
