Abstract

A new process of electrodeposting bright Tin Cobalt Zinc alloy from weak acid solution is proposed in this paper. The solution compositions and operating conditions are Na₃C₆H₅O₇·2H₂O 100～150, Na₂EDTA·2H₂O 20～30, SnCl₂·2H₂O 15～20, CoSO₄·72H₂O 25～35, ZnCl₂ 15～20 g·L^-1; stabilizer WDZ-160～100, brightener WDZ-215～20 mL·L^-1; pH=4～6, D_K=0.5～5.0 A·dm^-2, T=5～35 ℃. A bright Sn-Co-Zn deposit having Co about 0.5～3.5% and Zn about 1～10% is produced. The effects of bath compositions on Co or Zn content in deposit is also discussed.
