(Mn,Co)3O4 spinel coatings on ferritic stainless steels for SOFC interconnect applications
TL;DR: In this article, a slurry-coating technique was developed for fabricating the spinel coatings onto the steel interconnects, which not only significantly decreased the contact resistance between a LSF cathode and stainless steel, but also acted as a mass barrier to inhibit scale growth on the stainless steel and to prevent Cr outward migration through the coating.
