Abstract
Long-term stability and oxidation resistance of AISI 430 ferritic stainless steel which is employed as an interconnect in solid oxide fuel cells (SOFCs) for intermediate temperature operation, can be ameliorated with a protective coating layer. In this study the pack cementation method was employed to coat AISI 430 ferritic stainless steel. Isothermal oxidation and cyclic oxidation were applied to evaluate the parabolic rate constant. Spinels forming (Mn3O4 and MnFe2O4) during oxidation improves oxidation resistance. The coated samples demonstrated lower kp in each test and it indicates that the coating layer could have acted as a mass barrier against the outward diffusion of cations specially Cr.
