▎ 摘  要

NOVELTY - A corrosion-resistant wet film lubricant composition comprises a lubricating pigment containing graphene platelets which are partially oxidized and functionalized using silane, an oil in which the lubricating pigment is dispersed, and a thickener for thickening the wet film lubricant composition. USE - Corrosion-resistant wet film lubricant composition is used for forming lubricated article (claimed) e.g. fastener, valve component, and slide. ADVANTAGE - The corrosion-resistant wet film lubricant composition has excellent lubricity and galvanic or bimetallic corrosion resistance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: lubricated article, which consists of a surface and a coating of the corrosion-resistant wet film lubricant composition on the surface; and production of the corrosion-resistant wet film lubricant composition, which involves oxidizing exfoliated graphene for producing oxidized graphene platelets, functionalizing the oxidized graphene platelets using the silane for producing functionalized graphene platelets, and dispersing the functionalized platelets in a lubricant composition comprising the oil and the thickener.
