摘要：

The Ti3AlC2 ceramic and Ni were successfully joined by diffusion bonding technique. The microstructure and element distribution of the joint were analyzed by SEM and TEM. The diffusion mechanism of Ni and the forming mechanism of joint were investigated. The results show that the enrichment of Ni elements adjacent to the Ti3AlC2 ceramic led to a diffusion in the interface, which could promote the formation of joint. The typical interfacial microstructure of the Ni/Ti3AlC2 ceramic joint obtained at 900 ℃ for 60 min is Ni/Ni3(Al,Ti)+AlNi2Ti+TiC/Ti3AlC2 ceramic. It was found that the shear strength of the joint increased with increasing bonding temperature. When the temperature further elevated, the shear strength dramatically decreased. The maximum shear strength is 94.4 MPa at 900 ℃ for 60 min. © 2024 Harbin Research Institute of Welding. All rights reserved.
