Embodiment Construction

[0039] The method for manufacturing the aluminum-based composite of the present invention covers the surface of the aluminum-based metal with borax, and heats the aluminum-based metal to exceed the melting point of the borax. Among them, the melting point of borax is 743°C. Wherein, the aluminum-based metal may be aluminum metal or aluminum alloy.

[0040] More specifically, borax is spread on the aluminum-based metal composed of aluminum, aluminum alloy or a combination thereof, placed in a high-temperature environment such as a high-temperature furnace and heated above 743°C, so that borax and aluminum react to form a strengthening phase. In the course of the reaction, it can react with or without the protection of an inert gas (such as argon). In other words, the above aluminum-based metal treatment method of the present invention can be carried out in an oxygen-containing environment.

Abstract

A process for producing aluminum-based metal composite, an aluminum-based composite obtained by using the same, and an aluminum-based structure having the said aluminum-based composite are provided. The aluminum-based metal treating method applies borax on the surface of an aluminum-based metal and heats such metal to a temperature over the melting point of borax. The aluminum-based composite includes aluminum in the range of 7 to 9 atomic %, sodium in the range of 11 to 13 atomic %, and oxygen in the range of 79 to 81 atomic %. The aluminum-based structure includes an aluminum-based substrateformed by an aluminum-based metal and an aluminum-based composite disposed in the aluminum based substrate.

Description

technical field [0001] The present invention relates to a method of manufacturing an aluminum-based composite, an aluminum-based composite produced by the method, and an aluminum-based structure comprising the aluminum-based composite. Background technique [0002] Metal matrix composite (Metal Matrix Composite, MMC) is a new type of material obtained by uniformly distributing different types and types of ceramics and non-metallic reinforcement phases in a continuous metal substrate by using a special process with metal materials as the substrate. composite material. Its performance combines the advantages of metal substrates and strengthening phases, with high specific strength and specific stiffness, high temperature resistance, wear resistance, high transverse performance and interlayer simple shear strength, and high thermal stability and volume stability. The flexibility and the designability of materials, so it was first applied in the aerospace industry. [0003] At...
