▎ 摘　　要

NOVELTY - Gradient ceramic coated micro-texture self-lubricating cutter comprises tool base material which is high-speed steel or cemented carbide, where surface of the substrate has a composite coating, and the composite coating is added with graphene, molybdenum disulfide and calcium fluoride a gradient laminated coating of a silicon nitride-based or alumina-based ceramic layer alternating with a cermet layer of graphite, molybdenum disulfide , and calcium fluoride and surface of the composite coating has a micro-protrusion texture. USE - Gradient ceramic coated micro-texture self-lubricating cutter. ADVANTAGE - The radient ceramic coated micro-texture self-lubricating cutter has good toughness, high surface hardness and self-lubricating effect, high coating layer and the substrate bonding strength and high coating preparation efficiency, good toughness, high surface hardness and self-lubricating effect, high coating layer and the substrate bonding strength and high coating preparation efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing lubricating cutter, which involves: (A) performing pre-treatment and cladding a silicon nitride-based or alumina-based ceramic layer; (B) cladding the cermet layer and repeating above steps; (C) alternately cladding a silicon nitride-based or alumina-based ceramic layer and a cermet layer ; and (D) cladding micro-bump texture and performing post-treatment.
