| Abstract Scope |
Due to their superior chemical and mechanical properties, graphene and graphene oxide are recently emerged filler materials in various coating systems to improve corrosion resistance and mechanical durability. In this study, corrosion resistance of a multilayer coating on a mild steel substrate is investigated via potentiodynamic polarization. To obtain the multilayer coating system, samples are first galvanized and passivized. Thin layers of two different primers are applied on the passivization layer followed by a polyamide 12 topcoat. The effects of graphene oxide filler on both primers and topcoat are experimentally investigated with 0.5 to 1 %wt. filler rates. Experimental corrosion rates for coated specimens are examined in aqueous NaCl solution by the Tafel method. It is shown that the corrosion rates are reduced at least 10 times even with the 0.5 % wt addition of RGO as a filler material in the multilayer coating system. |
