Description
Technical Field
The invention relates to the technical field of copper-based composite materials, in particular to a particle reinforced copper-based composite material and a preparation method thereof.
Background
The particle reinforced copper-based composite material refers to the addition of a copper matrix or in situ generation of second phase particles in a certain process, wherein the second phase particles improve the strength and hardness of the copper-based composite material by blocking dislocation movement. The related studies prove that: the addition of the particles does not lose the electric conductivity and heat conductivity of copper or copper alloy, but can greatly enhance the strength and wear resistance of the copper-based composite material. TiB, alN, graphite particles, tiB 2 particles, etc. are less often incorporated into copper substrates, and much like Al 2O3, WC, siC particles, etc.
The composite material can be reinforced by adding one particle phase into a copper matrix, simultaneously acting as multiphase particles, and even reinforcing the composite material together with a nano phase, such as Al 2O3 particles, carbon nano tubes and rare earth oxide particles. In the aluminum oxide reinforced copper-based composite, al 2O3 particles can refine the structure of the composite material, and the effect of refining the structure is enhanced along with the increase of the content of Al 2O3 particles. However, the content of Al 2O3 is not positively correlated with the effect of reinforcing the copper-based composite material, and the quality fraction of Al 2O3 can be the opposite value when the quality fraction reaches a certain value. The particles with high content are not easy to disperse, and agglomeration worsens the matrix structure, so that the performance of the composite material is affected. In the prior art, the tensile property test is carried out on the Al 2O3/Cu composite material, and the fact that the continuous addition of Al 2O3 to the copper matrix can cause the increase and decrease of tensile strength and elongation is found, because the aluminum oxide whisker is difficult to disperse in the copper matrix composite material and has poor interfacial bonding capability with the copper matrix is found.
