Graphene is a kind of two-dimensional lamellar nano-material with excellent barrier property, and it has important application in the field of anticorrosive coatings. The effect of graphene addition on the corrosion resistance of zinc-rich epoxy coating and glass flake epoxy coating was investigated by opencircuit potential(Eocp), AC impedance and corrosion morphology. The results showed that the radius of arc resistance of epoxy zinc-rich coating with graphene was smaller than that of epoxy zincrich coating without graphene. The arc resistance with epoxy glass flake coating decreased gradually in 528h. It showed from the corrosion morphology observation that the addition of graphene improved the corrosion resistance of the zinc-rich coating, but reduced the corrosion resistance of the epoxy glass flake coating.
