▎ 摘　　要

NOVELTY - Nano-graphene composite nickel-based plating layer, comprises nickel-based composite coating of nano rare earth oxides and nano-graphene. USE - Nano-graphene composite nickel-based plating layer. ADVANTAGE - The nano-graphene composite nickel-based plating layer has high wear resistance, self-lubricating function and reduces the interfacial friction coefficient, with the zero wear of the plated layer of changeable structural parameter. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing nano-graphene composite nickel-based plating layer, which involves: (A) depositing chemically composite plating or composite by electrodeposition; and (B) preparing a nickel-based plating layer and in a chemical composite plating solution containing 3-16 g/l of rare earth oxide and 3-15 g/l of nano-graphene.
