“…Zhang et al used BAg45CuZn as the interlayer for RSW of TC4/304SS, and added three different adsorption layer structures of V/Cr [64], V + Nb/Cr [65,66] and V + Mo/Cr + Mo [67] between the substrate and the interlayer, respectively. The experimental results show that Fe-Cr, Fe-Nb, Ti-V, Mo-V, Mo-Cr and other phases with low brittleness can replace part of the original Fe-Ti phase with the intervention of Cr, V, Nb and Mo elements to effectively improve the strength of the joint.…”

“…When Nb is used as the interlayer material for micro-RSW, the shear load of the joint is increased from 0.9 kN to 1.24 kN, an increased of 38% [68]. When V + Mo/BAg45CuZn/Cr + Mo is used as the interlayer to weld TC4/304SS, the joint strength reaches a maximum of 235 MPa [64].…”

In this paper, the influence of interlayer on titanium/steel dissimilar metal resistance spot welding is reviewed from the aspects of macroscopic characteristics, microstructure and interface bonding properties of the joint. Previous studies have demonstrated that TiC, FeTi and Fe2Ti intermetallic compounds with high brittleness are formed in the joint during titanium/steel welding, which reduces the strength of the welded joint. Researchers proposed different interlayer materials, including Cu, Ni, Nb, Ta, 60%Ni-Cu alloy and BAg45CuZn. Firstly, adding an interlayer can weaken the diffusion of Fe and Ti. Secondly, the interlayer elements can combine with Fe or Ti to form solid solutions or intermetallic compounds with lower brittleness than Fe–Ti compounds. Finally, Cu, Ni, Ag, etc. with excellent ductility can effectively decrease the generation of internal stress, which reduces the formation of defects to improve the strength of the joint.
