You should contact plating chemicals suppliers such as Technic, Shipley,
Enthone,
and others and ask for plating solutions for permalloy electroplating. At
least
they would advise what solutions you may want to try. While
permalloy is not simplest alloy to be plated there are a number of other
alloys electroplated regularly including brass (CuZn) and solder (SnPb). In
most instances any metal present in the solution will electroplate if the
metal's redox potential is more positive then the potential imposed by
the power supply (usually measured with the Luggin capilary and reference
electrode). Sometimes this simultaneous deposition is intended e.g. when
alloy is plated, sometimes it is a nuisance when  metal impurities interfere
with pure metal deposition.
