▎ 摘　　要

NOVELTY - Method for corrosion inhibition on a substrate, involves (a) applying a sealing solution to an anodized surface of the substrate, where the sealing solution comprises a nanomaterial dopant and a corrosion inhibiting compound, the nanomaterial dopant comprises graphene nanoplatelets, carbon nanotubes or carbon nanofibers, and the corrosion inhibiting compound comprises a trivalent chromium compound, a trivalent praseodymium compound, nickel acetate, cobalt acetate, siloxanes, silicates, orthophosphates, molybdates, or a compound comprising elemental or ionic praseodymium, cerium, cesium, lanthanum, zinc, lithium, magnesium or yttrium, and (b) drying the sealing solution on the substrate to form a sealing layer comprising the nanomaterial dopant and the corrosion inhibiting compound. USE - The method is useful for corrosion inhibition on a substrate in a corrosion inhibition system for metal and metal coated substrates, and metal substrates or components in aircraft or vehicles, such as automobiles, trains, and heavy equipment, and building infrastructures. ADVANTAGE - The system mitigates and/or prevents risks associated with graphene nanoplatelets infiltrating the pores in anodized layer, and prevents corrosion and degradation over time of sealing layer. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) A corrosion inhibition system arranged on a substrate comprising a sealing layer arranged on an anodized surface of the substrate, where the sealing layer comprises a nanomaterial dopant and a corrosion inhibiting compound, the nanomaterial dopant comprises graphene nanoplatelets, carbon nanotubes or carbon nanofibers, and the corrosion inhibiting compound comprises a trivalent chromium compound, a trivalent praseodymium compound, nickel acetate, cobalt acetate, siloxanes, silicates, orthophosphates, molybdates or a compound comprising elemental or ionic praseodymium, cerium, cesium, lanthanum, zinc, lithium, magnesium or yttrium; and (2) A sealing solution comprising at least one of a trivalent chromium compound or a trivalent praseodymium compound, and a nanomaterial dopant comprising graphene nanoplatelets, where the sealing solution comprises nanomaterial dopant such that a sealing layer resulting from drying the sealing solution comprises 0.025-3.5 wt.% nanomaterial dopant.
