Description
Technical field：
The invention belongs to metal material processing technical field, more particularly to a kind of preparation side of aluminium nickel double metal composite strip
Method.
Background technology：
In recent years, the portable type electronic product such as demand such as mobile phone, notebook computer rapidly increases and to the side of light high-efficiency
To development, thus as its power resources all kinds of battery products also obtained it is great development and it is gradually close to lightweight, high energy
Degree direction is developed.In order to realize this target, the case material majority of current battery is changed to aluminium from steel, due to battery outside
Draw extreme general using electric conductivity and all preferable pure nickel material of corrosion resistance, the welding thus brought between nickel material and aluminium is asked
Topic.Preferable method is drawn outside between extreme nickel material and shell aluminium using a kind of aluminium/nickel bimetal composite band as welding
Transition zone.
At present, the preparation method of bimetallic composite band has various, such as roll-bonding method, extrusion cladding method, explosion composite method,
Reverse solidification method, casting and roll process etc., but it is roll-bonding method to be obtained in actual production wide variety of.In order to realize the first of interface
With reference to, a large deformation more than 50% is generally required during Rolling compund, this can cause compound constituent element to produce serious processing hard
Change, for aluminium/nickel complex system, the fusing point of two constituent elements, recrystallization temperature and mechanical property difference are larger, therefore roll
Diffusion annealing after system is compound is difficult to realize both and softens completely simultaneously, meanwhile, aluminium nickel compound interface is changed between easily generating metal
Compound, the conflicting property for causing combined strength bination to be controlled with nickel layer hardness seems especially prominent.Therefore, using traditional rolling work
During skill production aluminium nickel double metal composite band, the bond strength of composite bed and the hardness control difficulty of composite band are big.
The content of the invention：
The purpose of the present invention is, during for producing aluminium nickel double metal composite band using traditional rolling mill practice, composite bed
The hardness of bond strength and composite band controls the big technical barrier of difficulty, there is provided a kind of preparation of aluminium nickel double metal composite strip
Method, the preparation of the aluminium nickel double metal composite strip for making lithium battery pole ear, the method by will heat aluminium strip with it is soft
Nickel strap after annealing carries out Rolling compund, obtains aluminium nickel compound belt blank, is then diffused annealing and room temperature rolling obtains aluminium
The method of nickel double metal composite strip finished product.
To achieve the above object, the present invention uses following technical scheme：
A kind of preparation method of aluminium nickel double metal composite strip, comprises the following steps：
Step 1, nickel strap softens
After nickel strap is carried out into soft annealing, the nickel strap after soft annealing is formed；Wherein, the temperature of soft annealing be 700~
800 DEG C, soft annealing soaking time is 20~30min；
It is prepared by step 2, aluminium nickel compound belt blank
Take after aluminium strip is heated to 300~500 DEG C, with the nickel strap after soft annealing, Rolling compund is carried out at room temperature, obtain
Aluminium nickel compound belt blank；Wherein, Rolling compund deflection is 20~45%；
Step 3, interface improved treatment
Aluminium nickel compound belt blank is diffused annealing, the aluminium nickel compound belt blank of interfacial bonding property improvement is obtained；Wherein, spread
Annealing temperature is 300~550 DEG C, and diffusion annealing soaking time is 5~180min；
Step 4, hardness control
The aluminium nickel compound belt blank that interfacial bonding property is improved is carried out into room temperature rolling, aluminium nickel double metal composite strip, institute is obtained
Aluminium nickel double metal composite strip thickness is stated for 0.12~0.8mm, hardness is HV80~230；Wherein, room temperature rolling deflection is 0
~60%.
In described step 1, purity >=99.9% of nickel strap, the thickness of nickel strap is 0.1~1mm.
In described step 1, the nickel strap surface after soft annealing through over cleaning oil removing and grinding process, wherein, polishing side
Formula is that belt sanding or wire brush are polished.
In described step 2, purity >=99.5% of aluminium strip, the thickness of aluminium strip is 0.1~1mm.
In described step 1 and step 2, the thickness of raw material aluminium and raw material nickel material, the double gold of aluminium nickel according to required preparation
Belong to the thickness of composite strip, and aluminium nickel thickness ratio determines in aluminium nickel double metal composite strip.
In described step 2, before heating, surface is through over cleaning oil removing and grinding process for aluminium strip；Described polishing mode
It is that belt sanding or wire brush are polished.
In described step 4, the hardness of the aluminium nickel double metal composite strip that room temperature rolling deflection is prepared according to needed for will
Determination is asked, when the aluminium nickel compound belt blank hardness that the interfacial bonding property that step 3 is obtained is improved meets finished product aluminium nickel double metal composite band
During material requirement, then it is 0% that need not carry out the room temperature rolling operation of step 4, i.e. room temperature rolling deflection；The interface that step 3 is obtained
The aluminium nickel compound belt blank of associativity improvement, as finished product aluminium nickel double metal composite strip.
The preparation method of aluminium nickel double metal composite strip of the invention, heats aluminium strip in Rolling compund, it is possible to decrease roll
The first pass deformation of compound tense processed, reduces the deformation (the processing hardening of very little occurs) of soft state nickel strap, after such Rolling compund
The aluminium nickel compound belt blank of formation is substantially at soft state, therefore, the diffusion annealing of the aluminium nickel compound belt blank after Rolling compund is only needed
The intensity of compound interface is controlled, and the room temperature that the hardness of finished product aluminium nickel double metal composite strip can be after controlling diffusion annealing is rolled
Deflection processed is easily realized.
Beneficial effects of the present invention：
(1) nickel strap of soft state after the aluminium strip of heating and soft annealing is carried out room temperature rolling and is combined by the present invention, reduces head
The deflection of the compound deflection of passes and nickel strap, can obtain the aluminium nickel compound belt blank substantially without hardening, solve expansion
The contradiction that the intensity of compound interface again softens nickel strap layer should be ensured when dissipating annealing；
(2) in aluminium nickel double metal composite strip preparation process of the invention, the compound belt blank after diffusion annealing is carried out not
With the room temperature rolling of deflection, it is convenient to the hardness of control targe product.
