NOVELTY - Graphene surface-modified abrasion-resistant steel oil ring, in which a layer of graphene film is prepared on the surface of the oil ring with a thickness of 5-10 mu m is claimed. USE - Used as graphene surface-modified abrasion-resistant steel oil ring. ADVANTAGE - The graphene surface-modified abrasion-resistant steel oil ring: provides significant reduction in oil ring friction coefficient to improve oil ring life; can be obtained by simple and easy equipment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene surface-modified abrasion-resistant steel oil ring, comprising (a) taking graphene oxide dispersed in water to obtain the graphene oxide solution as an electrolyte, and electrodeposition of graphene oxide on the oil ring surface, and (b) carrying out electrochemical reduction to reduce the graphene oxide deposited on the oil ring surface to graphene, to obtain the graphene film on the oil ring surface.
