A process for electroplating palladium or a palladium alloy onto an iron-nickel alloy substrate, which comprises the steps of: i) electroplating a metal selected from the group consisting of copper, tin, a nickel-tin alloy and a copper-tin alloy onto the substrate to form a first primer layer; ii) electroplating nickel or a gold alloy onto the first primer layer to form a second primer layer; and iii) electroplating palladium or a palladium alloy onto the second primer layer to from a palladium or a palladium alloy electroplating layer. |
