Abstract

On the basis of analyzing diffusion bonding process of the stainless steel and copper alloy

the diffusion brazing behavior of Cu-Zr and Ni-based superalloy was analyzing

focusing on the microstructure and mechanical properties of brazing joint.The results reveal that diffusion brazing joints have desirable interface and compact structure as well as satisfied mechanical properties with welding at 880

00 ℃for 90

20min

realizing the excellent bonding.
