Electroplating with mixed metal electrodes?

  1. Feb 10, 2016 #1
    Hello.

    I need to nickel plate an item, but there are no sources of pure nickel in my immediate area other than guitar strings. I picked up a set, which was labeled as pure nickel, but it was obvious upon inspection that only the wound strings had nickel, and that was only the woven outer layer. So this means that there is a stainless steel cable in the middle, with nickel cable wrapped around it.

    So, my question is this: Can I use these strings to electroplate with, and still get a pure nickel plating? Or will the steel being in the electrolyte solution cause problems? My gut says that since the solution is a nickel based salt, it should only plate with nickel, but I would like to just double check.

    Thank you in advance.

    I think that you may need to check the electromotive series as in this cas you will need to use a source of potential difference only suitable for nickel to be oxidized
