Suppose a part is made of copper and 304L stainless steel, permanently and cleanly joined together with no gaps at the joint (picture the copper stainless interface edge on the bottom of a"Revereware" frying pan, or the perimeter of an American quarter or dime). Can this assembly be electroplated, say with nickel? Or is it an issue that the two dissimilar and connected metals will form some kind of electrochemical cell and set up some galvanic corrosion weirdness during the plating?
Are there special precautions? For example, do you have to make sure the plating current is already flowing at the moment of immersion so there is no time when one of the plating bath metal interfaces has the wrong polarity? Will it be impossible to plate right at the joint?
Setting aside the choices of copper and stainless and nickel, in general, are there issues with electroplating multimetal parts?
Is choosing an electroless plating process better for some of these concerns? or worse?
