The invention relates to a preparation method of an enhanced
magnesium-based
composite material of carbon nanotubes, relates to a preparation method of a nanometer
composite material, and mainly solves the technical problems that the carbon nanotubes are difficultly scattered uniformly in a
magnesium alloy matrix and the tensile strength of the enhanced
magnesium-based
composite material is low. The preparation method comprises the following steps of: firstly, carrying out mixing and ball milling on Zn
powder and the carbon nanotubes to obtain composite
powder; secondly, pressing the composite
powder and magnesium powder into precast blocks after uniformly mixing the composite powder and the magnesium powder; and finally, adding the precast blocks into the molten magnesium powder, heating until obtaining
metal solution, and transferring the
metal solution into a die to be pressed, thus obtaining the enhanced magnesium-based composite material of the carbon nanotubes, wherein the tensile strength of the enhanced magnesium-based composite material is 195-210 MPa, and the elongation rate of the enhanced magnesium-based composite material is 13-15%. According to the preparation method of the enhanced magnesium-based composite material of the carbon nanotubes, the tensile strength is high, the
dispersity is good, and the enhanced magnesium-based composite material of the carbon nanotubes can be applied to the fields of
aerospace, automobiles and sports equipments.
