Abstract
Electrochemical properties of depolarized Nickel Anode in Co-Ni alloy bright plating bath were studied. The conclusion of this reserch is as follows:
(1) Anode slime gathered in anode bag was 1.956% in average for dissolved anode metal in Co-Ni alloy bright plating bath.
(2) Anode current efficiency was very high and the surface corroded was smooth and there was no massive slime from anode. So, there was a little change of metallic constituent in plating solution and the maintainance of the bath was easy.
(3) The metallic ion consumed during plating including drag out loss was 84.46% in average from anode and 15.54% in average from salt added.
(4) There was no influence of the throwing power on cathode in the case of the depolarized nickel anode.
