Description
(1) technical field
What the present invention relates to is a kind of welding method, specifically a kind of welding method of aluminum matrix composite.
(2) background technology
Non-continuous reinforced aluminium-based composite material is by the parent metal aluminium alloy of plasticity, good toughness and nonmetal short fiber, whisker or the particle of some high strength, high-modulus, high-melting-point, low-density and low thermal coefficient of expansion, as Al commonly used
2O
3Short fiber, SiC, AlBO whisker and Al
2O
3, SiC, TiC particle etc., be composited through special preparation technology.The special composite construction of this kind material makes its more former alloy matrix aluminum have excellent comprehensive performance more just, as specific strength, specific stiffness height, wearability is good, thermal coefficient of expansion is little etc., thereby in Aero-Space, national defence field, as guided missile, tank, panzer etc., and be with a wide range of applications in the civilian industry, as automobile engine piston, connecting rod brake and bicycle part etc.Material just has bigger practical use after being processed to member.And solder technology is one of very important secondary processing method in this process.For the welding joint of member, its performance depends on the heterogeneous microstructure of weld seam to a great extent.Therefore, for being consistent of the joint performance that makes member and mother metal as far as possible, guaranteeing that appearance of weld is good, pore-free, be mingled with etc. on the basis of defective, should make the institutional framework of weld seam approximate consistent with the maintenance of mother metal, promptly weld seam also should have wild phase equally distributed composite construction in matrix alloy.In the existing various welding methods of aluminum matrix composite, as melting (TIG weldering, Laser Welding etc.), Solid-State Welding (friction welding (FW), diffusion welding (DW), transient liquid phase weldering etc.) and other certain methods (electric resistance welding, soldering), domestic and international many Welder authors try hard to by various measures to reach this purpose.Yet the whole bag of tricks still exists certain difficulty in realizing this purpose process.The main feature of the whole bag of tricks is:
1, melting welding
During molten solder (TIG, MIG weldering, laser, electron beam welding etc.) welding of aluminum based composites, used packing material when used welding wire often is welding aluminum alloy is as ER4043, ER4047 etc.These welding wires and welding procedure are very successful when welding aluminum alloy, when still applying it to the welding of aluminum matrix composite, but are faced with the following urgency problem to be solved:
On the one hand, consider that from physical compatibility the fusing point of aluminum matrix composite matrix and wild phase differs bigger, existence is melted wild phase in a large number and is made its viscosity become big in the molten bath, and mobile variation is filled metal and is difficult to mix with molten pool metal.This will cause generation of defects such as pore, lack of penetration and incomplete fusion; In addition, in the weld pool solidifies process, molten wild phase particle is concentrated partially at solidification front and is gathered, and has destroyed original characteristic distributions and makes mis-behave; The more important thing is, aspect chemical compatibility, the wild phase particle in the not only direct scaling loss molten bath of the high temperature that molten solder produces, and make the following interfacial reaction of easy generation between matrix and the wild phase:
3SiC(s)+4Al(l)＝Al
4C
3(s)+3Si(s)
Or 3Mg (l)+4Al
2O
3(s)=3MgAl
2O
3(s)+2Al (l)
Also cause the wild phase loss.Reaction product Al
4C
3Perhaps MgAl
2O
3All be the fragility phase, seriously reduced weld properties and cracking resistance.Especially, Al
4C
3Under aqueous environment, can emit CH with the water reaction
4Gas causes the joint low stress damage.Thereby, in final joint made by flame welding, promptly exist no wild phase zone, exist again to strengthen the poly-zone of skew, the difference of seam organization and mother metal is very big, and joint performance is very undesirable.Solve above two problems, want the filling metal of selective wetting, good fluidity on the one hand, and take technological measure, reduce the fusing of composite,, adopt the low TIG weldering of heat input etc. as strengthening groove; For avoiding and the reaction between parent metal and the wild phase when suppressing to weld, can in matrix, add suitable alloying component simultaneously and be suppressed on the other hand by reducing the heat input in molten bath.It is found that interpolation Si is especially effective in matrix.Yet this might damage matrix strength, causes the loss of strength of composite.Some scholars also utilize high energy laser beam, and the cooling and the temperature field that are equipped with the nitrogen sieve are regulated, and induce and improve the interfacial reaction of aluminum matrix composite wild phase and matrix to a certain extent, thereby improve strength of joint, but problem is not solved.In addition, molten solder technology only limits to the aluminum matrix composite of wild phase volume fraction lower (＜20%), for the composite of high-volume fractional more (as electronic encapsulation device with composite wild phase volume fraction greater than 30%) be powerless.
2, friction welding (FW)
Need not packing material during the friction welding aluminum matrix composite, also can avoid the loss of wild phase, strength of welded joint is higher.But the welding process center tap produces bigger plastic deformation, the local softening phenomenon occurs, and this position intensity reduces, and joint need pass through solid solution+Ageing Treatment.In addition, friction welding (FW) has higher requirement to the shape of connected piece, is generally the bar-shaped part of simple shape, makes this kind welding method range of application be subjected to certain restriction.
3, diffusion welding (DW)
Diffusion welding (DW) is the more promising method of a kind of welding of aluminum based composites, but same difficulty when with the diffusion welding (DW) aluminum matrix composite time, having run into the diffusion welding (DW) aluminium alloy.
(1) there is the oxide-film of one deck densification on the aluminum matrix composite surface, and it seriously hinders two diffusion combinations that connect between the surface.With generating immediately again after machinery or the soak cleaning, even under high vacuum condition, this layer oxide-film also is difficult to decompose, and influences the atom diffusion.Just need bring up to the connection temperature near the fusing point of aluminium or on linkage interface, impose severe pressure for destroying oxide-film on the combination interface.This inevitably can make connector produce excessive plastic deformation.
(2) under the situation that does not adopt the intermediate layer, there is the direct contact phenomena of wild phase one wild phase on the aluminum matrix composite contact-making surface, be difficult to realize that the diffusion between the wild phase connects under the diffusion welding (DW) condition.The transmission capacity of load has not only been reduced at this position, and also provides opportunity for the germinating and the expansion of crackle, becomes the not high main hidden danger of strength of joint.
(3) adopt intermediate course, can reduce or eliminate little connection of wild phase/wild phase in the joint join domain as Cu, Al-Si-Mg, Ag paper tinsel etc., joint performance is improved.But no wild phase zone still appears in joint easily, and joint quality is stable inadequately.
In addition, this method is longer welding interval, apparatus expensive, and cost is very high, and the welding surroundings of vacuum makes weldment size, shape also be subjected to bigger restriction, and its extensive use is restricted.
4, transient liquid phase weldering (Transient Liquid Phase bonding, TLP)
The transient liquid phase weldering is by forming low melting eutectics at a lower temperature between the test specimen welding surface, eliminated the way of contact of wild phase/wild phase in the weld seam, apply the oxide-film that less pressure just can destroy the mother metal surface, and make wild phase enter into liquid intermediate layer by dissolving part mother metal, obtain having the joint microstructure of composite construction by isothermal solidification, strength of joint is higher.
Also there is certain deficiency in transient liquid phase weldering when having more advantage: (1) owing to be static isothermal solidification, in the liquid phase eutectic area process of setting wild phase passed by solid liquid interface and cause poly-ly partially become the subject matter that this kind material TLP welds.Domestic and international many scholars find to select thin middle paper tinsel layer, dissolve and come wild phase effectively to address this problem from mother metal with what reduce that the liquid phase intermediate layer comprised.Generally all about several micron, but this has relatively high expectations to surface roughness to be welded the selected intermediate layer thickness of this method, particularly for the member of big bonding area, implement the comparison difficulty, thereby engineering significance is undesirable.In addition, the particle size that composite comprises also can reduce the poly-partially degree of particle when big, but from composite property, the preparation composite is generally all pursued micron, sub-micron or even nano level particle and has generally also all been surpassed 550 ℃ as wild phase (2) transient liquid phase welding temperature, under this temperature, mother metal has in various degree softening, and this is a challenge to matrices of composite material.(3) the transient liquid phase weldering is carried out under vacuum environment mostly, and shape and size that this has limited member to be welded reduce this kind adaptation of methods.
5, soldering
Lead base composite soldering solder commonly used also is a solder commonly used in the aluminium alloy brazing, as BAlSi-1, BAlSi-4 and Zn-Al solder etc.During this method welding of aluminum based composites, subject matter is the restriction that strength of joint is subjected to original solder intensity, and tensile strength is lower.For the aluminum matrix composite welding, adopt method for welding also to have following several problem:
(1) oxide-film on aluminum matrix composite surface has a strong impact on welding quality.Because Al
2O
3The film fusing point is very high, in welding process, be difficult to the fusing, have a strong impact on solder on mother metal wetting with sprawl, become one of major obstacle of aluminum matrix composite soldering.
(2) welding procedure is controlled improper meeting and is caused matrix fusing, and it is poly-that the diffusion region strengthens skew; Residual no wild phase layer can't keep original particular tissues of mother metal and property in the brazing seam structure.This butt joint occasion that can require that has specific characteristics is not suitable for, and keeps good antidamping characteristic and dimensional stability etc. as the need joint.
(3) alloy matrix aluminum and wild phase fusing point differ greatly, at brazing temperature lower substrate partial melting, do not melt and strengthen body, cause solder viscous, mobile variation, solder on mother metal wetting with sprawl because the existence of solid-state wild phase is subjected to serious obstruction, add some alloying element, improve brazing temperature and can improve to a certain extent, and the too high burning corrode that easily causes mother metal of temperature is brought very big difficulty to brazing process.
6, electric resistance welding
Resistance welded generally need not packing material, because its heat time heating time is short, can suppress the interfacial reaction between wild phase and matrix, and connector area is difficult for producing crackle and pore under pressure.But having run into challenge for the aluminum matrix composite that discontinuous fiber strengthens, mainly is to exist serious enhancing skew poly-in the nugget.In addition, the existence of wild phase makes the distribution of electric current line and the complex distributionization of electrode pressure in the aluminum matrix composite, has brought difficulty for the selection of welding parameter and the control of welding quality.And the enhancing body of composite and matrix resistance differs greatly, composite produced superfuse, splash, fiber bonds, broken and generation is empty, strength of joint is subjected to very big influence.
(3) summary of the invention
The object of the present invention is to provide a kind of enhancing to be on good terms and evenly distribute, have the weld seam of composite construction, joint performance is good, can realize the welding of aluminum matrix composite under non-vacuum condition, the filling composite solder non-continuous reinforced aluminium-based composite material Vibration Liquid Phase welding method of greater flexibility is provided for actual production.

Aluminum matrix composite special organization structure makes its weldability also become special, and matrix and the greatest differences of wild phase physics, chemical property make it be connected technology to be difficult to control.Based on the analysis of front, though transient liquid phase weldering and soldering obviously are better than melting.But can't satisfy the needs of the extensive development of aluminum matrix composite owing to their limitation.On the contrary, the productivity ratio height, the melting that technology is comparatively easy is difficult to obtain the result of satisfaction owing to its metallurgical problems.For this reason, further develop welding material and welding procedure and remain an arduousness and important task.
In the aluminum matrix composite welding process, if wild phase can be from mother metal to the weld seam transition, just easier realization seam organization is consistent with the mother metal tissue.But, adopt the conventional scolder of filling, realize that this transition is very difficult, promptly allow to realize transition, its control procedure is also quite difficult, welds as transient liquid phase.In the preferred solder matrix, mix wild phase, promptly adopt the composite solder of band wild phase just may realize this purpose.For the aluminum matrix composite of high-volume fractional, adopt the composite solder that contains wild phase more to seem very necessary especially for the uniformity that guarantees seam organization and mother metal.Therefore, the exploitation good fluidity, wetability is good, can suppress disadvantageous metallurgical reaction, and the compound special-purpose packing material of strengthen welds is an important field of research comprising special scolder.
