Electroplating of Nickel Films Using Stable Foam Electrolyte Solution

摘要

Electroplating of nickel films was achieved by using foam electrolyte in place of the conventional liquid electrolyte. The Watt bath, to which was added 0.5 wt% of sulfuric acid monododecyl ester sodium salt(SDS), was bubbled with nitrogen gas to generate a stable foam electrolyte. Nickel films were electroplated on brass cathodes immersed in the foam. The cathodes were rotated in the foam to generate a flow of the foam on the surface during the electroplating process. The films deposited in the foam electrolyte showed higher corrosion resistance compared with films deposited in a liquid electrolyte. The corrosion resistance was improved at increasing cathode rotation speeds during the electroplating process.
