Protective CuO Coating Synthesis via Electrodeposition of Copper on AISI 430 Ferritic Steel for SOFC Interconnect Applications

Abstract:

In this work, electrodeposition of copper on AISI 430 steels substrate with relatively low current density followed by oxidation of Cu to form protective and conductive oxide layer is examined. Result shows that the activation by Ni strike plating on AISI 430 steels substrate prior to electroplating improves the coating ability of copper. Phase identification by XRD on the oxidized sample confirms that as coated Cu layer was transformed into CuO. The growth of CuO scales was relatively low and effectively prevents Cr outward diffusion from the ferritic steels.
