▎ 摘　　要

NOVELTY - Modifying part surface comprises obtaining graphene and a solvent, dispersing the graphene in the solvent to form a uniformly mixed graphene solution, and coating the graphene solution on the surface of the part. USE - The method is useful for modifying part surface. ADVANTAGE - The part surface has unique two-dimensional layered structure; improves the lubricity of the friction surface of the part; has high strength and toughness, improves the strength of the mechanical friction interface on the surface of the part, and improves the performance of the surface of the part.
