| Abstract: | Bright Sn-Pb alloy electroplating technology with citric acid and EDTA as the complexing agent, and QB-1 as the additive was studied. Effect of [Sn2+] /[Pb2+] , cathodic current density and operating temperature on Pb content in the alloy coating was discussed. The optimum bath composition and technological conditions for obtaining bright Sn.Pb alloy coating were determined after comprehensive considering the composition and lustre degree of the alloy coating, and the stability of the plating bath. |
