Abstract
Copper-tin-zinc (Cu-Sn-Zn) ternary alloy coatings was successfully deposited from a less hazardous electrolyte containing copper (II) chloride, tin (II) chloride, zinc chloride, sodium hypophosphite and complexing agent. In this work, the impact of different complexing agent on morphology, chemical composition, current efficiency, microhardness, and corrosion rate were investigated by method of SEM equipped with EDX spectroscopy, weight gain measurements, XRD, Vickers microhardness test and potentiodynamic polarization measurement, respectively. It was discovered that, Cu-Sn-Zn alloys prepared using sodium formate shows the highest microhardness value. It is also can be concluded that, complexing agent have a significant impact on the appearance and the surface morphology of the Cu-Sn-Zn alloy electrodeposits.
