“…In recent years, many researchers have investigated the microstructure and properties of Cu/Al joints by using refill friction stir spot welding, electric current-assisted ultrasonic welding, and ultrasonic dynamic stationary-shoulder friction stir welding and other techniques [5][6][7][8][9][10][11], and these new processing methods can improve the quality of Cu/Al joints. However, these techniques are complicated and difficult to apply quickly.…”

Zn-Al alloy with the addition of Al (5–25 wt.%) was fabricated into as–cast and rod–shaped alloys. SEM/EDS and XRD technology were used to examine the impacts of the Al–element content on the alloys’ microstructure, mechanical characteristics, electrical conductivity, wetting ability, and corrosion resistance. The findings demonstrate how the Zn-Al alloy’s microstructure is dramatically altered by the different additions of the Al content. When the Al content reaches 15 wt.%, the eutectoid structures of the as–cast Zn-Al alloy are the finest, and the microhardness and tensile strength of the extruded–state alloy reach their maximum and exhibit the best corrosion resistance. The spreading area of the Zn-15Al solder alloy achieves its maximum on the 6061 Al plate, while it reaches its minimum on the T2 Cu plate. Furthermore, the electrical resistivity of the Zn-Al alloy continuously decreases as the Al content increases.

To obtain Cu/Al brazing materials with better overall performances, scanning electron microscopy, X-ray diffraction, and electrochemical testing were used to analyze the influences of trace Ag elements on the microstructure and properties of Zn − 22Al − xAg filler metals. The results show that the liquid phase temperature of Zn − 22Al − xAg is about 450°C, and the trace addition of the Ag element has little effect on the melting point of the filler metal. When the Ag content was varied from 0 − 1.2 wt.%, the reticulated eutectic crystals in the microstructure of as − cast Zn − 22Al − xAg gradually began to connect to form a larger reticulated structure, and the phenomenon of grain − boundary aggregation became more and more obvious in the extruded-state alloy. In addition, when the Ag content was 0.8 wt.%, the spreading area of the filler metal on the Cu plate increased by 30.45% compared with that without Ag. After brazing, the thickness of the compounds in the interfacial layer along the filler metals/Cu decreased significantly, the shape of the compounds was more regular, and the shear strength of the brazed joints reached the maximum value of 40.08 MPa, but the corrosion resistance of the filler metal was slightly decreased compared with that of the Zn-22Al at the same time.
