▎ 摘　　要

NOVELTY - Self-lubricating solid composite coating (2) comprises particles (3) of graphene and/or graphene oxide distributed in a metal matrix (4). USE - The self-lubricating solid composite coating is useful for application to the clockwork mechanisms (claimed). ADVANTAGE - The solid composite coating exhibits self-lubricating property and greatly reduces the friction and minimizes the wear, while providing the clockwork mechanism having improved durability and better resistance to environmental conditions. DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of a coated substrate of graphene metal composite. Support (1) Self-lubricating solid composite coating (2) Graphene and/or graphene oxide particles (3) Metal matrix (4) Bonding layer (5)
