Abstract

The invention belongs to the technical field of aluminum alloy metal materials, and discloses a super-limit aluminum alloy and a preparation method thereof. The super-limit aluminum alloy comprises analuminum alloy base body, wherein a composite bonding layer, a composite ceramic layer, a reflecting layer, an anti-refracting layer, an insulating layer and a foam carbon layer are sequentially deposited on the surface of the aluminum alloy base body; the composite bonding layer comprises a bonding layer deposited on the surface of the aluminum alloy base body and a noble metal layer deposited on the surface of the bonding layer; and the composite ceramic layer comprises a ceramic layer A and a ceramic layer B. During preparation, the composite bonding layer, the composite ceramic layer, thereflecting layer, the anti-refracting layer, the insulating layer and the foam carbon layer are sequentially deposited on the surface of the aluminum alloy, so that the super-limit aluminum alloy isformed. The use temperature of the super-limit aluminum alloy is increased to be higher than the melting point of an original aluminum alloy by100-500 DEG C, so that the aluminum alloy can be used ina super-limit temperature.

Description

technical field [0001] The invention belongs to the field of aluminum alloy metal materials, and in particular relates to an ultra-limit aluminum alloy and a preparation method thereof. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in the industry. It has excellent characteristics such as low density, high strength, excellent plasticity, electrical conductivity and corrosion resistance. It is used in aviation, aerospace, automobiles, machinery manufacturing, ships and Widely used in the chemical industry, especially in the aerospace field to play an irreplaceable role. Due to its excellent comprehensive performance, high-strength aluminum alloys have already accounted for more than 80% of the structural quality of commercial aircraft, so they have received widespread attention from the global aviation industry. All kinds of aircraft use aluminum alloy as the main structural material, and the skins, beams, ribs, st...
