Plating iron onto iron with a transition to the anode becoming silver(and/or copper)

I would like to plate an aluminum(or Inconel) wave-guide with an iron coating 0.050 inch thick. if possible I would like to transition the deposition from iron to the electro-conductive metal(Ag or Cu)---As if I were to withdraw the anode of iron while inserting a replacement anode of silver(or copper).
Also, is there an anodizing (electron charge driven surface reaction) dip I can use to clean or prep an iron surface?

Even the most experienced and well equipped platers would be reluctant to try that. Each different metal or alloy to be electroplated over each different substrate requires its own combination of surface preparation, bath chemistry, process parameters, separate tank and anodes. It is not as simple as switching anodes. Electroplating is a very complicated science. Are you sure you want to do it yourself? G. Marrufo-Mexico
