Experimental investigation on diffusion bonding of dissimilar metals

Abstract. Diffusion bonding is one of the metal joining process to join same and well as dissimilar metals. In this project
stainless steel and copper plates were joined together with the interlayer of cupronickel sheet. The temperature was
maintained in the range of 800 - 8500C. At the same time of heating compression load also acting on the specimensupto
5 MPa. To prevent the oxidation process vacuum of 10-4 Torr was maintained. The experiment was conducted for 60
Min. distinct diffusion zones were formed in the joined area of the specimens. The experiments were conducted with
different temperatures and pressure. The shear strength of the specimens was tested and at 8250C have maximum shear
strength of 8.47KN.
