▎ 摘　　要

NOVELTY - Laser additive manufacturing method of graphene reinforced nickel-based composite material, comprises (i) plating nickel on the surface of the graphene, (ii) mixing the surface nickel-plated graphene with nickel high-temperature alloy powder, drying under vacuum environment to obtain a mixed powder, and (iii) placing the mixed powder in an inert gas protection treatment chamber, and using a laser as a heat source to form a graphene-resistant nickel-type composite material, where the mass of graphene is 0.1-0.1 wt.%. USE - The composite material is useful in aircraft engine e.g. fuel nozzle of leap engine, and gas turbine. ADVANTAGE - The method: solves the problem that the graphene dispersed in the nickel-based material is not uniform; avoids the graphene decomposition under the irradiation of the laser in the forming process; has short manufacturing period; is economical and suitable for medium and small batch complex shape graphene-reinforced nickel-based composite material with high performance of the whole component; has chemical nickel plating on the surface of the graphene and control forming process parameters to improve the microstructure and mechanical property of the composite material.
