英文摘要	Ferritic stainless steels are promising materials for solid oxide fuel cell interconnect applications. However, volatilization of Cr from the Cr-containing oxide scales can result in cathode poisoning, especially in wet air, and thus greatly degrades the performances of the cell. In the present study, a protective and adhesive NiFe2O4 spinel coating was applied on a type 430 stainless steel (430SS) to isolate Cr2O3 from gas environment. The performance of the uncoated and NiFe2O4-coated samples has been evaluated in the air-7%H2O at 700, 800, and 850 degrees C, respectively. The bare steel lost mass at 700 and 800 degrees C and underwent breakaway oxidation at 850 degrees C after 75h, including scale spallation and Cr evaporation. The NiFe2O4 coating could significantly increase the oxidation resistance of 430SS and effectively retard the outward diffusion of Cr and inhibit the Cr evaporation.
