Description
Technical field
The present invention relates to a kind of titanium aluminum copper clad materials and preparation method thereof, belong to technical field of composite material manufacturing.
Background technique
With being constantly progressive for science and technology, the material of single component has been difficult to meet modern industry comprehensive to material
The requirement of energy, more and more fields start largely to use composite material.Double metallic composite material is as one in composite material
Kind, it not only can satisfy and the complexity of material required in design, while also the comprehensive performance of composite material can be made to embody.
Therefore, extensive concern of the bimetallic material increasingly by countries in the world.
Copper has many advantages, such as that high conductivity, high thermal conductivity, contact resistance are low, intensity is high, corrosion-resistant, diamagnetism, specious,
At present often by fields such as vessel, electric power facility, ocean shippings.But copper content in the earth's crust only has 0.01wt%, leads to state
Border copper processing persistently rises.Simultaneously as China's copper ore resource is deficient, a large amount of import copper products will cause capital outflow, influence
Domestic economy development.Therefore, the research of the substitute of copper product seems significant.
Aluminium content in the earth's crust is high, and use scope is only second to steel, and has light weight, cheap, thermally conductive and lead
Electrically the advantages that good, easy processing.But since aluminium hardness is small, tensile strength is low, it is difficult directly in the high occasion of some hardness requirements
It connects and replaces copper.In the occasion less high to hardness requirement, the composite material of aluminium and copper has a good application prospect.Titanium has height
Tensile strength and corrosion resistance, but titanium price is relatively higher.Designing and manufacturing titanium-Solder for Al-Cu Joint Welding composite material will be able to have
The institute of three's basis material is advantageous, obtains that a kind of cost performance is very high, composite material of function admirable.
The currently used complex method of 3-layer composite material is Hot rolling, though Hot rolling can be realized the system of composite material
It is standby, but the method processing technology is complicated, needing for trilaminate material to be stacked together, it is compound to carry out heating rolling, and needs not
Interface cohesion is realized in disconnected rolling back and forth.Rolling is easy to destroy the interface that composite plate is formed back and forth, reduces bond strength.Meanwhile
This method is difficult the width of control interface binder course and the type of intermetallic compound.
Producing 3-layer composite material, there are also the modes such as Explosion composite, but Explosion composite is difficult to realize the homogenization at interface,
Although many fire points can be disposed, interface discontinuously will affect the bond strength of composite plate, meanwhile, Explosion composite environment
It is poor, the SO for having pollution to atmosphere can be generated2Equal gases.
Metallurgical bonding is also to produce a kind of mode of composite plate, can make to realize that metallurgical interface combines, continuously nothing is split at interface
Line.Application publication number is that the Chinese invention patent of CN102205346A discloses a kind of preparation side of copper-aluminum-copper composite board
Method, this method are oppositely arranged vertically by showing two blocks the copper alloy of cleaning pretreatment, and the molten aluminum after fusing is poured into two pieces
Alloy blank is obtained between copper alloy, alloy blank is heat-treated, then rolling copper aluminum bronze three-layer composite board.Due to this
Method preparation is copper aluminum bronze three-layer composite board, and what it is positioned at aluminium two sides is copper sheet, and composite board can not be made to have the characteristic of titanium.
