Abstract
An article and method for forming a coated metal pipe for use as an automotive fluid transport tube including a copper plated carbon steel tubing formed into a circular cross sectional profile. At least one intermediate layer including any of a corrosion inhibiting zinc/aluminum alloy, electroplated zinc or hot dip aluminum is applied over said tubing. One or more outer polymer or copolymer layers are applied over the intermediate layer, with the outer layer or multi-layers compounded with a graphene or graphene oxide powder.
