US5376187A - Diffusion bonding of aluminum and aluminum

The diffusion bonding of aluminum and aluminum alloys presents problems because,when left exposed to the atmosphere even for a short time,they acquire an extremely tenacious surface oxide layer that inhibits or prevents satisfactory diffusion bonding.Unlike titanium,this oxide layer is not absorbed at diffusion bonding temperatures.Transient Liquid-Phase Diffusion Bonding of AluminumAug 30,2011 Reactive Diffusion Bonding Between Commercially Pure#0183;In the present study,the transient liquid-phase diffusion bonding of an aluminum metal matrix composite (6061-15 wt.% SiCp) has been investigated for the first time using a mixed Cu-Ni powder interlayer at 560 Reactive Diffusion Bonding Between Commercially Pure#176;C,0.2 MPa,for different holding times up to 6 h.The microstructure of the isothermally solidified zone contains equilibrium precipitate CuAl2,metastable precipitate Al9Ni2 in the The Effects of Intermediate Layer and Surface Using cooper foil as intermediate layer,commercially pure titanium (CP-Ti) was vacuum diffusion welded after surface nanocrystallization.The effects of the interlayer and SNC treatment on the bonding state were discussed thereafter.The results showed that about 10 m nano-structured surface layer was achieved on CP-Ti.Well bonded joint could be obtained by two original CP-Ti samples
