lead to an increased amount of zinc in the alloy deposit.
You must also pay attention to the composition of the
anodes used in this bath. For example, if you are trying
to deposit in alloy of 80/20 tin/zinc, you should use anodes that are the same composition.
Some other types of baths have been developed, such
as baths that substitute other complexing agents for cyanide, but in all of the cases that I am familiar with these
baths have not been commercialized.

Acid Zinc PlAting RAtes
Q. How much does an acid zinc bath slow down when
the temperature is 69��F instead of 75��F?
D.V.
A. Good question, but I really do not have data available
that answers your question. I would expect the plating
rate is slowed down to some extent, but not signifcantly.
If anybody can answer this reader���s question, I would appreciate hearing from you. n
