Abstract

The invention discloses a three-dimensional carbon nano phase composite reinforced aluminum base material and a preparation method thereof. It is to firstly immerse the aluminum powder in the ethanol solution containing bisphenol A diglycidyl ether and nickel nitrate hexahydrate, stir magnetically and add ethylenediamine dropwise to obtain the surface-treated aluminum powder, and then pass the surface-treated aluminum powder through After reduction, it is mixed with graphene oxide and subjected to low-speed ball milling, and then reduced to obtain three-dimensional carbon nanophase-coated aluminum powder. Finally, these aluminum powders are subjected to SPS sintering and cold rolling to obtain a three-dimensional carbon nanophase composite reinforced aluminum matrix. Material. The process of the invention is simple and easy to operate, and the cost is low. The obtained composite reinforced aluminum-based material enhances the load transfer efficiency by constructing a three-dimensional carbon nanophase, thereby significantly improving the mechanical properties of the aluminum-based composite material, so that it not only has high tensile strength, but also Maintain good elongation and toughness, and have good scalability.
