Abstract
The invention relates to a graphene and carbon nanotube reinforced aluminum-based composite material and a preparation method thereof, belonging to the technical field of aluminum-based composite materials. In order to solve the problems of graphene and carbon nanotubes agglomerating, forming carbides with aluminum matrix at high temperature and improving the wear resistance of aluminum matrix composite materials, the invention provides a graphene and carbon nanotube reinforced aluminum matrix composite material, The components include composite copper-coated nickel graphene with a mass percentage of 0.1-5.0%, composite copper-coated nickel carbon nanotubes with a mass percentage of 0.1-5.0%, magnesium powder with a mass percentage of 5%, and the remaining The amount is aluminum powder. The invention strictly controls the interfacial reaction by compounding copper-nickel plating on the surface of graphene and carbon nanotubes, ultrasonically disperses graphene and carbon nanotubes in the aluminum-based composite material under stirring state, and finally obtains reinforced aluminum by vacuum hot pressing sintering Its wear resistance is significantly improved due to the self-lubricating properties of graphene and carbon nanotubes.
Description
technical field [0001] The invention belongs to the technical field of aluminum-based composite materials, and in particular relates to a graphene and carbon nanotube reinforced aluminum-based composite material and a preparation method thereof. Background technique [0002] Aluminum alloys have low density and excellent machinability, and are widely used in aviation, aerospace, automotive and electronics industries. However, with the rapid development of modern industry, aluminum alloy materials have been unable to meet the performance needs of industrial development in many aspects. Combining aluminum with other materials to prepare aluminum matrix composites is one of the most important ways to improve the comprehensive mechanical properties of aluminum alloy materials. Carbon fiber can effectively enhance the strength and stiffness of aluminum alloys. Therefore, carbon fiber aluminum matrix composites have received sufficient attention and gradually realized their appli...
