NOVELTY - Aluminum-based composite material comprises aluminum alloy substrates, graphene and ceramic materials. USE - Aluminum-based composite material. ADVANTAGE - The aluminum-based composite material has good erosion resistance, high strength, and good degradability or corrosivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing an aluminum-based composite material, which involves: (A) mixing graphene powder with the first solvent, and performing ultrasound to obtain the first dispersion; (B) mixing aluminum alloy base material powder and the ceramic material powder with the second solvent, and performing ultrasound to obtain the second dispersion; (C) mixing the first dispersion liquid and the second dispersion liquid, and then performing mechanical stirring to obtain a third dispersion liquid; (D) drying the third dispersion liquid in a vacuum drying oven to obtain a mixed powder; (E) filling the mixed powder into the envelope, and then performing hot isostatic pressing to obtain a bulk material; and (F) removing outer sheath of the bulk material to obtain the aluminum-based composite material.
