Fe-Cr steels are the most promising candidate for interconnect in solid oxide fuel cells. In this study, an effective, dense and well adherent (LaSr)(CrCo) [LSCC] coating layer was produced onto 430 stainless steel (STS-430) by atmospheric plasma spraying and the oxidation behavior as well as electrical properties of the LSCC coated STS-430 were investigated. A significant oxidation of pristine STS-430 occurred at in air environment, leading to the formation of and scale layer up to after 1200h, and consequently increased an area specific resistance of . Although the plasma sprayed LSCC coating contained the characteristic pore network, the coated samples presented apparent advantages in reducing oxidation growth of STS-430, resulting a decrease in oxide scale thickness of at after 1200h. The area specific resistance of the LSCC coated STS-430 was much reduced to after exposure at for 1200h, compared to that of the pristine STS-403.
