Research of Mixed BTSPA and VTAS Silane Films Applied on the Steel

Article Preview

Abstract:

Silane film technology is an energy saving and environment-friendly metal surface treatment technology.The best hydrolysis condition of mixed Bis[3-(trimethoxysilyl)propyl]amine(BTSPA) and Vinyltriethoxysilane(VTAS) are studied by orthogonal experiments in this paper.The corrosion resistance of the film formed under optimum conditions in 0.5M NaCl solution was studied by Potentiodynamic polarization curves and electrochemical impedance spectroscopy.The studies show that the optimal hydrolysis conditions: silane content is 8ml, alcohol -water ratio is 80:15, pH value is 4.0, hydrolysis temperature is 25 °C.Silane film formed on cold-rolled steel has good corrosion resistance in 0.5M NaCl solution.
