Physics, performance chemically and mechanically, and dissimilar metal can meet demand, and material can be saved, reduce expense, save energy
Source.
At home and abroad in commercial production, the product of " magnesium+aluminum " bi-material attachment structure is used to get more and more.At present, magnesium
Connection with aluminum mainly uses the mechanical joining methods such as riveting, bolt connection, welding.Riveting or bolted joint quality
Greatly, joint geometry is limited, and " magnesium+aluminum " bi-material directly rivets or bolt connection sealing is bad.Magnesium and aluminum and aluminium alloy
Welding procedure can be divided into melting, pressure welding and soldering, in addition to the cold welding in pressure welding, other welding methods are required for magnesium
And/or form solid solution, intermetallic compound, eutectic after aluminum heating, magnesium and aluminum heating, the fusing point difference of another magnesium and aluminum
Great disparity, linear expansion coefficient, heat conductivity and specific heat capacity also differ greatly, and has that plumb joint easily aoxidizes, composition of weld line is uneven, weldering
Connect the problems such as deformation is big, welding point easily cracks, bad control and operation in production.
Splicing is to utilize the mechanical bonding force, physical absorption power and the Chemical bonding that produce on conjunction plane to make two glue
The process that fitting gets up.Adhesive technology is easy, it is not necessary to complicated process equipment, operation need not be entered at high temperature under high pressure
OK, thus bonded part is not likely to produce deformation, and joint stress distribution is uniform.Under normal conditions, gluded joint has good close
Feng Xing, electrical insulating property and corrosion resistance.Glued joint and be applicable not only to same material, be also applied for foreign material.
Adhesive bonding technique is existing more research and application in terms of the connection of different metal materials.As: Wang Heng deliver " magnesium,
The research of aluminum dissimilar metal Laser Weld Bonded Joints Welding " (" Dalian University of Technology " master's thesis in 2006), propose first to adopt
It is connected magnesium, aluminum dissimilar metal with glueing joint new technique (i.e. Laser Weld Bonded Joints welding technology) compound mutually, test with by laser sequential welding
Result shows: Laser Weld Bonded Joints plumb joint is under certain parameter, and appearance of weld is good, without obvious weld defect, with single glue
Joint is compared with welding point, and the laser weld bonding joints shear power of same size test specimen is maximum.There is processing in said method
Complexity, or the problem such as storeroom resistance to mechanical insufficient strength.At present, under normal temperature condition, magnalium bi-material is connected, its resistance to mechanical
Intensity and the best simple solution of sealing.
The disclosure of background above technology contents is only used for assisting inventive concept and the technical scheme understanding the present invention, and it is not
Necessarily belong to the prior art of present patent application, show the foregoing applying date in present patent application there is no tangible proof
In the case of disclosed in, above-mentioned background technology should not be taken to evaluate novelty and the creativeness of the application.
Summary of the invention
