Description
Technical field
The present invention relates to the method for attachment of a kind of composite and metal.
Background technology
Aluminum matrix composite has high specific strength, specific stiffness, axial tensile strength and wearability, outstanding high temperature resistance and low thermal coefficient of expansion, favorable conductive, thermal conductivity, fatigue resistance, and under humidity or radiation environment good advantages such as dimensional stability, be a kind of desirable light-weight high-strength material.Carbon fiber reinforced aluminum matrix composite density is less than aluminium alloy, and modulus is but high 2～4 times than aluminium alloy, and its tensile strength still can keep 81% of room temperature tensile strength in the time of 250 ℃, and its fatigue ratio aluminium alloy is high by 38%.The member of making has that quality is light, good rigidly, small wall thickness, advantages of higher stability, can improve place capacity and delivered payload capability greatly.With the satellite parabola antenna skeleton that carbon fiber reinforced aluminum matrix composite is made, thermal coefficient of expansion is low, thermal conductivity good, can keep its dimensionally stable in than large-temperature range, makes the gain efficiency of satellite parabola antenna improve 4 times.DWA company is that NASA and Lockheed company make the waveguide on the satellite with the graphite fibre reinforced aluminum matrix composites.The waveguide made from this material not only axial rigidity height, the coefficient of expansion low, conduct electricity very well, and lighter by 30% with the compounded waveguide of graphite/epoxy one aluminium lamination than former.Along with the quickening of C/Al composite engineering application progress, material self and and other material between connectivity problem become more and more important.
Fiber-reinforced metal matrix composite is made up of parent metal and fortifying fibre, the difficult point of welding this composite is, under higher temperature, thermodynamic instability normally between matrix in the metal-base composites and the fortifying fibre, chemical reaction easily takes place on both contact interfaces, generation is to the disadvantageous fragility phase of material property, and this reaction is commonly referred to interfacial reaction.The solubility portion of carbon in solid-state and liquid aluminium is little, and solid solubility is 0.015%; And the solubility when 800 ℃, 1000 ℃, 1100 ℃ and 1200 ℃ is respectively 0.1%, 0.14%, 016% and 0.32%.In the temperature range of room temperature to 1670 ℃, Al and C reaction generate Al
4C
3Standard free energy of formation all be negative value.Therefore, aluminium and carbon are inconsistent at thermodynamics, and they have begun reaction at low temperatures, and just speed is very slow, along with the rising of temperature, reacts more and more violent, the Al of generation
4C
3Amount is also more and more.The temperature that both obviously have an effect is different and different according to matrix composition and carbon fiber structural, between 400 ℃～500 ℃.The welding method of welding temperature on this scope all can cause tangible interfacial reaction.Al
4C
3Be fragility acicular constituent, the boundary strength between matrix and the fortifying fibre acutely descended, the performance of severe exacerbation mother metal.At present, mainly concentrate on the research of methods such as arc welding, soldering and diffusion welding (DW) for the connection of fiber reinforcement aluminum matrix composite, yet arc welding can cause the serious interfacial reaction of wild phase and matrix generation because bath temperature is higher, heating surface (area) (HS is bigger; Diffusion welding (DW) can cause the large tracts of land of interfacial reaction to take place owing to connection temperature height, heat time heating time are long too; Though the solder in the soldering can realize the connection of fiber reinforcement aluminum matrix composite, the joint of soft solder welding is highly brittle, and just may rupture in the cooling procedure.The present invention proposes a kind of method of attachment that can realize carbon fiber reinforced aluminum matrix composite and metal, and quality of connection is higher, makes carbon fiber reinforced aluminum matrix composite and intermetallic reach good metallurgical binding, also can not worsen the performance of mother metal simultaneously.
Summary of the invention
The objective of the invention is in order to solve the whole heating-up temperature height of traditional welding method, cause taking place between wild phase carbon fiber and the aluminium serious interfacial reaction, worsen the problem of mother metal performance, and a kind of method that connects carbon fiber reinforced aluminum matrix composite and metal is provided.
A kind of method that connects carbon fiber reinforced aluminum matrix composite and metal of the present invention is carried out according to the following steps: one, by weight 54～58 parts aluminium powder, 8～10 parts nickel powder and 33～37 parts cupric oxide powder are mixed, place in the ball grinder, be that 5: 1 ratio is put into abrading-ball in ball material mass ratio, under the condition of argon shield, speed ball milling 2～3h with 300～500r/min obtains mixed-powder; Two, the mixed-powder that step 1 is obtained be pressed into relative density be 60%～80% and thickness be the intermediate layer pressed compact of 1～3mm, sealing is preserved; Three, the intermediate layer pressed compact that step 2 is obtained places and is assembled into " sandwich " formula assembly parts between carbon fiber reinforced aluminum matrix composite and the metal, then assembly parts are clipped and be put in the vacuum drying oven, be under the condition of 5MPa at pressure, be heated to 500 ℃, and be incubated 5～10min, cool to room temperature then with the furnace, namely finish being connected of carbon fiber reinforced aluminum matrix composite and metal.
Advantage of the present invention: one, the present invention utilizes traditional thermit reaction principle, prepared A--Ni-CuO powder heat release intermediate layer, can realize being connected of carbon fiber reinforced aluminum matrix composite and metal at 500 ℃, simultaneously can not worsen performance of composites, well keep the various good characteristics of mother metal.Two, utilize intermediate layer of the present invention to carry out being connected of carbon fiber reinforced aluminum matrix composite and metal, intermediate layer and both sides mother metal reach good metallurgical binding, and quality of connection is good, and strength of joint can reach 50.7MPa.The invention provides a kind of quality of connection preferably, can realize the method that carbon fiber reinforced aluminum matrix composite is connected with metal, can not worsen simultaneously the performance of mother metal.
Adopt homemade powder intermediate layer among the present invention, formed by certain weight proportion by Ni powder, Al powder, CuO powder, be pressed into the thick cylinder of 1～2mm, be placed between C/Al composite and the metal, be assembled into " sandwich " formula structure, put into vacuum drying oven and heat, apply certain pressure simultaneously, be heated to certain temperature, and insulation a period of time, realize connecting the connection of the two.The present invention utilizes Al powder in the homemade powder intermediate layer and Ni, the reaction of CuO powder to emit a large amount of heat, makes the aluminium fusing in the intermediate layer, and local melting the C/Al composite and the metal that contacts with the intermediate layer, makes the two that metallurgical binding take place, the realization connection.Traditional method of attachment because whole heating-up temperature all will reach the fusing point of aluminium, has therefore unavoidably destroyed C
fThe combination property of/Al composite.The present invention has then utilized Al and CuO under lower temperature (500 ℃ condition can be reacted), and supervene a large amount of heats, Al and Ni also can instead give birth to reaction at (about 600 ℃) under the lower temperature simultaneously, and emit a large amount of heats, well be connected with the both sides mother metal, adopt this powder of configuration voluntarily, well reduced heating-up temperature in the whole stove, reach good connection effect.And about 500 ℃, the interfacial reaction of C and Al is fainter, can not influence the C/Al performance of composites, has well kept the various good characteristics of mother metal.
