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 Na 3C 6H 5O 7·2H 2O 100～150,Na 2EDTA·2H 2O 20～30,SnCl 2·2H 2O 15～20,CoSO 4·7H 2O 25～35,ZnCl 2 15～20 g·L -1 ;stabilizer WDZ 1 60～100, brightener WDZ 2 15～20 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.
