Rhodium Electroplating

I need to electroplate Rhodium in non acidic/weakly acidic conditions for an industrial process. At present we plate using a Rhodium Sulphate/sulfuric Acid solution which is effecting the surface of the cathode. If anyone has any ideas, please let me know.

It is common to plate over a strike of nickel or gold to reduce your stated problem. You might take a look at the all phosphoric acid formulation. Does not work quite as well, but should be kinder to your cathode. Since is in the aircraft engine overhaul business, don't you have to comply with the engine manufacturers procedures for that plating repair?
