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)$O_3$ [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 $800^{circ}C$ in air environment, leading to the formation of $Cr_2O_3$ and $FeCr_2O_4$ scale layer up to ${sim}7{mu}m$ after 1200h, and consequently increased an area specific resistance of $330;m{Omega}{cdot}cm^2$. 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 ${sim}1{mu}m$ at $800^{circ}C$ after 1200h. The area specific resistance of the LSCC coated STS-430 was much reduced to ${sim}7;m{Omega}{cdot}cm^2$ after exposure at $800^{circ}C$ for 1200h, compared to that of the pristine STS-403.
