The method of composite, belongs to powder metallurgical technology.
Background technology
Copper is a kind of electric conductivity, ductility, heat conductivity all well material, is widely used in electric, mechanical and national defence etc.
Industry.Only drawback is that, the intensity of copper material is the lowest, high due to insufficient strength in the application of electronic device (such as pcb board)
And produce variety of problems, the such as lost of life, it is easy to damage etc..Along with social development and the anxiety of the energy, people are for gently
The high-strength material of matter occurs in that more demand, and Cu-base composites is that a kind of preferably material is to realize these requirements.At height
In the preparation of the intensity copper material beryllium-bronze of 1500MPa (the such as intensity may be up to), traditional method by means of alloying and
Add Section 2 granule to be achieved, but the raising of copper alloy intensity is built upon the basis of the hydraulic performance declines such as conduction, heat conduction
On.Composite method is equally applicable to the preparation of copper material, according to composite Materials Design rule (Ec=(1-f) Em+fEp), the second phase
Be added on realization strengthening effect while, it is also possible to overcome the some shortcomings of matrix material, thus obtain the copper of high-strength light
Material, overcomes the deficiency of traditional method.
The Graphene of monolayer carbon atom is as a kind of novel material, and except the application in terms of the energy, it has excellent
Mechanical property, be the hardest material found so far.In recent years, realized mutually increasing as strengthening with Graphene
The research of strong organism material emerges in an endless stream.At present a lot of researchs be conceived to graphene film or redox graphene directly with
Copper powder carries out ball milling and mixes to reach purpose mixed uniformly with metal dust, but this can cause the reunion of Graphene and to stone
Ink alkene causes damage.Additionally, due to the two-dimensional structure of lamellar, the orientation that graphene film can carry in the composite is limited
System, it is impossible to enough reinforced effects playing Graphene completely.This is that current Graphene enhancing metal_based material does the bottleneck institute run into
, how to accomplish Graphene dispersed and structure in metallic matrix intact be the focus of research at present.
