Strength and fracture behavior of Si₃N₄ ceramic/Inconel 600 alloy liquid phase inductive diffusion bonding joint

Bonding of Si₃N₄ ceramic to Inconel 600 alloy was carried out by liquid phase inductive diffusion bonding (LPIDB) method with Nb/Cu/Ni multi-interlayer.Effect of bonding condition on joint strength and fracture behavior was investigated in the paper.Joint strength was evalua-ted by shear test,shear fracture surface of the joint was observed by SEM.It was shown that the parabolic relationship among the shear strength of the joint and bonding temperature (when bonding time is 3000 s and bonding pressure is 5 MPa),bonding pressure (when bonding temperature is 1 130℃ and bonding pressure is 10 MPa) was observed.
