3. Deposition of alloys, composites and multilayers
3.1 Main electroplated alloys
Various types of nickel alloys can be codeposited
For nickel-cobalt deposits, the addition of cobalt to nickel baths improves brightness and hardness. Its role is more or less equivalent to that of organic addition compounds, without the disadvantage of the formation of by-products during the various chemical and electrochemical reactions. The author states that, according to the results obtained, the cobalt content of the deposit...

Regulations
At the time of writing, the use of nickel solutions and their release into the environment in surface treatment plants are subject to the regulations set out in the decree of September 26, 1985 (published in the Journal Officiel of November 16, 1985). This decree defines the maximum permissible concentration of various constituents, such as metal ions (chromium, copper, iron, zinc, cadmium, etc.) and other components (cyanides,...
