Abstract

The invention provides a preparation method for nickel-plated carbon nano tube reinforced aluminum matrix composites. The method includes the steps that 1, the outer portion of a carbon nano tube is plated with nickel, so that a nickel-coated carbon nano tube is obtained; 2, aluminum powder or aluminum alloy powder, the nickel-coated carbon nano tube and a process control agent are mixed for ball-milling, so that composite powder is obtained; 3, the composite powder is packaged in a metal cover and is rolled after temperature rises, so that a composite material blank is obtained; 4, the metal cover is stripped, burs are removed, and then the nickel-plated carbon nano tube reinforced aluminum matrix composites are obtained. The nickel-plated carbon nano tube is used for improving the interface of the aluminum matrix composites, a high-temperature interface reaction between the carbon nano tube and an aluminum matrix can be avoided, and meanwhile wettability between the carbon nano tube and the aluminum matrix can be improved. Moreover, the nickel layer on the surface of the carbon nano tube can react with the aluminum matrix to generate intermetallic compounds, the interface bonding strength between the carbon nano tube and an aluminum matrix is improved, and accordingly the mechanical properties of the composite materials are improved.

Description

technical field [0001] The invention belongs to the field of metal composite materials, and specifically refers to a preparation method of a nickel-plated carbon nanotube reinforced aluminum-based composite material. Background technique [0002] Metal matrix composites have the excellent properties of traditional metal materials, and the performance limitations of traditional metal materials can be overcome by adding a reinforcing phase. Aluminum matrix composites have the advantages of light weight, high strength, wear resistance and corrosion resistance, good electrical and thermal conductivity and low thermal expansion coefficient, and are widely used in aerospace, automobile manufacturing, electronic instruments and other industrial fields. Carbon nanotubes are a common reinforcing phase of aluminum matrix composites. How to use carbon nanotubes to make aluminum matrix composites with high performance has become a hot research topic at home and abroad this year. [000...
