ELECTRODEPOSITION OF STAINLESS STEEL LAYER

The disclosed electrodeposition method for production of a stainless steel coating in form of a Fe-Ni-Cr alloy with less than 20 wt% chromium on a metal or semiconducting substrate in a liquid electrolyte bath is reaching an austenite grade stainless steel alloy coating showing lowered crack densities and an increased brittleness of the resulting stainless steel layers. This is reached with providing a special liquid electrolyte bath comprising salts of iron, nickel and chromium, a supporting composition, a Ni complexing agent, a pH buffer and a Cr complexing agent, preferably glycine or DMF and running electrodeposition process at temperatures below 25°C, applying sequences of a direct current cathodic pulse with a current density (jc) followed by a relaxation time with zero direct current and repeating sequences of direct current cathodic pulse and relaxation time.
