Iron nickel alloy plating
-
I am interested to know whether iron nickel alloys are normally
plated using baths with iron nickel alloy anodes or with a ratio of
individual iron and nickel anodes equivalent to the required deposit
composition e.g. 60/40%..

I am assuming that your question involves nickel -iron alloy
deposition, ie there is more nickel in the deposit than iron. When
the nickel-iron processes first came on the market there was work
done using ferro-nickel alloy cones available from Falconbridge as
the anode material. Ultimately we went the use of separate baskets of
iron and nickel as this was the most economical approach and easiest
way to control the alloy deposition. We found the use of clean steel
stamping scrap to be quite suitable for the process we were using.
The number of baskets containing iron will be dictated by the amount
of iron you ultimately want in the alloy deposit. Do not mix iron and
nickel in the same anode basket. Most of the major suppliers have
nickel-iron technology in their arsenals and they can help you. Trust
this helps
