Abstract: Co, Co-Mn (67:33 at.%) and Co-Cu (67:33 at.%) coatings were fabricated using magnetron sputtering on two kinds of ferritic stainless steels (Crofer22APU and F17TNb) in order to form spinel protective coatings on metallic interconnects for solid oxide fuel cells. Despite the thickness unevenness at different regions, dense metallic coatings were successfully applied onto all necessary surfaces of the channelled interconnect substrates. Upon oxidation, spinel oxide coatings with very low Cr content were formed, reducing effectively the Cr release. Among the three protective coatings, Co-Cu coating showed the lowest area specific resistance (<15 m Omega cm(2) at 800 degrees C). (C) 2011 Elsevier Ltd. All rights reserved.
