Corrosion Resistance of Steels after Silane Coupling Agent Treatment

Abstract
The corrosion-resistance of the cold rolled steels treated with silane coupling agent(SCA)and chromate was studied by the tests of CuSO4 dropping,linear polarization and EIS etc.The results showed that the corrosion resistance of the steels and the adhesion between the steel and the coating were enhanced by the SCA surface treatment.The corrosion protection performance of silane treatment is comparable to that of chromate treatment,The conventional chromate could be replaced by the SCA treatment.
