▎ 摘　　要

Outstanding characteristics of graphene are its high thermal conductivity, inherent high capacity, extremely large specific surface area, high strength, ductility, and remarkable chemical inertness, making it an attractive candidate in the corrosion barrier field. Since graphene coating does not change the thickness and appearance of the substrate, it is an ideal coating for protecting a metal substrate from destructive effects. Between various deposition procedures of graphene coatings on metal surfaces, i.e., electrophoretic deposition, dip coating, spray coating, spin coating, etc., chemical vapour deposition (CVD)-grown graphene coatings have been shown to improve the corrosion resistance of graphene-coated metals significantly. This review is focused on the protective properties of graphene coatings deposited by CVD on different metal substrates and exposed to corrosive environments.
