▎ 摘　　要

NOVELTY - In-situ generation of friction-reducing graphene film on the diamond surface comprises performing laser irradiation treatment on the surface of diamond to form a graphite layer on the surface of diamond to obtain graphite-containing layer product, where the graphite layer includes powdered graphite layer and layered graphite layer arranged in a stack, and the layered graphite layer is in contact with the diamond, subjecting the graphite-containing layer product to a polishing process for removing the powdered graphite layer and part of the layered graphite layer to obtain polished product, and performing electrochemical peeling on the polished article for generating a friction-reducing graphene film in situ on the surface of diamond. USE - The method is useful for in-situ generation of friction-reducing graphene film on the diamond surface. ADVANTAGE - The method: can directly generate the friction-reducing graphene film in situ from a carbon source; can ensure that graphene grows uniformly and accurately on the diamond surface; can maintain good adhesion between friction-reducing graphene film and diamond surface; and can ensure that the friction-reducing graphene film and diamond matrix has high bonding strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for product comprising diamond and friction-reducing graphene film formed in situ on the surface of the diamond.
