▎ 摘 要
NOVELTY - Graphene and carbon nanotube reinforced aluminum matrix composite material comprises 0.1-5 wt.% composite copper-plated nickel graphene, 0.1-5 wt.% composite copper-nickel carbon nanotubes, 5 wt.% magnesium powder and the remaining amount is aluminum powder. USE - Used as graphene and carbon nanotube reinforced aluminum matrix composite material. ADVANTAGE - The material has improves wear resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene and carbon nanotube reinforced aluminum matrix composite material comprising (1) subjecting the graphene and the carbon nanotubes to activation treatment and sensitization treatment, adding the obtained graphene or carbon nanotubes to the electroless copper plating solution, stirring the copper plating solution for electroless copper plating to obtain copper-plated graphene or copper-plated carbon nanotubes, adding the obtained copper-plated graphene or copper-plated carbon nanotubes to an electroless nickel plating solution, (2) mixing the composite copper-plated nickel-graphene, the composite copper-plated nickel-carbon nanotubes prepared in the first step, magnesium powder and aluminum powder with absolute ethanol to obtain a suspension, ultrasonically dispersing the suspension under stirring, suction filtering to obtain a composite powder and (3) adding the composite powder obtained in the second step into a mold, cold-forming, perform vacuum hot pressing sintering, cooling the furnace to room temperature to obtain a graphene and carbon nanotube reinforced aluminum matrix composite material.
