Zinc alloy/nickel strike coat bath


(2000)

It would be greatly appreciated if anyone could help me as to the make up of a nickel strike coat bath for zinc alloy pieces (automotive potmetal). The current baths in use are not compatible with the zinc based metal.I do not wish to handle the copper cyanide baths that most use. Any help would be greatly appreciated.

Thank You.

The plating industry predominantly uses proprietary chemistry today rather than laboratory formulas.

The more difficult the plating problem, the more likely that the easy textbook formulas are unsatisfactory, and that you will need to benefit from the years of painstaking development that someone put in to develop a workable answer.

Nickel striking zinc diecastings instead of cyanide copper plating them is a workable technology, but I think you'll find that it is a technology you will have to buy from a supplier, not one you can toss together yourself like a Woods' nickel strike. Ted Mooney, finishing.com Teds signature
