摘要

Graphene oxide (GO)-based inorganic passive films were prepared on the surface of galvanised steel. The results showed no changes in the composition of the passive film, while the morphology was significantly affected. The decrease in defects and the increase of corrosion resistance were most pronounced at the optimum GO content. The corrosion current density was decreased by two orders of magnitude and the corrosion rate was reduced by 96%. The results of electrochemical impedance spectroscopy were discussed in detail to verify the enhancement of corrosion resistance.
