AIUI, it is unexpectedly difficult to plate iron. The plating solutions
normally used are quite complex: iron tetrafluoroborate is one salt
used. I would expect that a ferrous salt, rather than a ferric, would be
appropriate, but it may be that hydrolysis prevents proper working.
A Google search shows that the process of iron plating copper bits is
'proprietary', and very little information is openly available about
iron plating of anything.
