摘要: A compact and adherent Co-Cu spinel coating on ferritic stainless steel was developed by electroplating a Co-Cu alloy layer followed by oxidation. The Co-Cu alloy was oxidized into a three-layer structure consisted of a thinner CuO outer layer, a middle thicker Cu0.92Co2.08O4 layer and an inner Co3O4 layer after an oxidation treatment of 2 h at 800 degrees C in air. The three-layer oxide structure was transformed into a double-layer scale with a (Co,Cr,Cu,Mn,Fe)(3)O-4 spinel outer layer and an inner Cr-rich oxide layer after an oxidation of 500 hat 800 degrees C in air. The Cu Co coating enhanced the oxidation resistance of the alloy and served as a diffusion barrier against the outward migration of Cr elements. Meanwhile, the area specific resistance (ASR) of the scale for the Cu Co coated alloy was significantly lower than that for the bare sample. (C) 2018 Hydrogen Energy Publications LLC.
