Abstract: A corrosion-resistant dry film lubricant composition includes a lubricating pigment, a binder, and a solvent. The lubricating pigment comprises graphene platelets and is dispersed in the binder, and the solvent solubilizes the lubricant pigment and the binder. The graphene platelets are oxidized and functionalized with a silane. A method of producing a corrosion-resistant lubricant includes oxidizing exfoliated graphene to produce oxidized graphene platelets, functionalizing the oxidized graphene platelets with a silane to produce functionalized graphene platelets, and dispersing the functionalized graphene platelets in a lubricant composition, wherein the lubricant composition comprises a binder and a solvent.

Abstract: A method for coating a substrate includes forming a conversion coat layer, depositing a protective coat onto the protective coat onto the conversion coat, and depositing a corrosion resistant top coat onto the protective coat. The conversion coat layer is formed by applying a conversion coat onto the substrate. The protective coat is deposited using a first atomic layer deposition. The corrosion resistant top coat is deposited using a second atomic layer deposition. The conversion coat layer has a volatizing temperature, and the first atomic layer deposition is performed at a deposition temperature that is no greater than 1.3 times the volatizing temperature of the conversation coat layer, calculated in Kelvin.
