Abstract
This paper reports on a new method based on the friction stir spot welding process to join Al/Cu in lap joint configuration. The feasibility of the friction diffusion bonding (FDB) of Al/Cu was investigated by varying the welding time between 20 and 50 s with all other parameters constant. A circular Cu plate was placed on the surface of an Al plate in the FDB process. The experimental results revealed that the intermetallic compounds, CuAl2 and Cu9Al4, were formed in the copper plates failed from the mechanical tests and the copper and aluminum diffused about 4μm and 2μm away from the interface into the Al and the Cu sides, respectively. Bonding was accompanied by interfacial diffusion with no significant mechanical mixing. The maximum tensile shear strength of Al/Cu joint was achieved at the welding time of 40 s and rotating speed of 1400 rpm.
