Cu-Ni Electrodeposition

  1. Oct 11, 2017 #1
    So, I'm trying to electrodeposit Cu-Ni alloy. Cu being more nobel than Ni as seen from the EMF series. My simple question is that which of the two will have more tendency to electro deposit first. And, how can I control the amount of Cu-Ni composition in my deposits. I have a common bath of electrolyte containing both Cu-Ni ions.

    Thanks, will be waiting for a response.

    Welcome to PF. Sorry about the delay.

    Write out the half cell equations and work out the potential required to deposit Cu or Ni.
    What are those voltages and how different are they ?

    The cell voltage will need to be sufficient to deposit both elements.
    An alloy will be difficult to deposit unless you carefully control the concentration of the electrolyte.
