Embodiment 1
[0014] A method for preparing an aluminum-based composite material with a reinforced particle-copper alloy interface compatible treatment. The raw materials for the preparation include 100 parts by weight of a matrix alloy, 8-10 parts by weight of reinforcing particles, and 0.05-0.08 parts by weight of a refining agent. The matrix The alloy is made of 75-80 parts by weight of cast aluminum alloy ZAlSi8MgBe (that is, ZL116, the mass fraction of each element is: Si= 6.5-7.5%, Mg=0.35-0.55%, Ti=0.1-0.3%, Be=0.15-0.40 , the balance is Al), 15-20 parts by weight of copper alloy Cu20Ni20Mn (composition: nickel 19.85%, manganese 19.69%, iron 0.29%, the balance is copper) and 5-8 parts by weight of copper alloy Cu20Ni35Mn (composition: nickel 19.85%, manganese 34.94%, iron 0.34%, and the balance is copper), the reinforcing particles are a combination of tungsten carbide, tetraacicular zinc oxide whiskers, silicon carbide and nano-titanium dioxide, and the weight ratio of the four reinf...
