Effect of thermal-sprayed Mn1.5Co1.5O4 coating on oxidation suppression of metallic interconnects

Research output: Contribution to journalArticlepeer-review


Metallic interconnects are less expensive, more conductive and able to form complex shapes than ceramic interconnects for SOFC applications. Most metallic interconnects use alloys containing chromium. At elevated temperatures, chromia scales react with cathode and degrade its performance. Manganese cobalt oxide ((Mn,Co)3O4, (MCO), with spinel structure is found to be a good material to form a protective coating for metallic interconnects. In this study, the high-temperature ferritic stainless steel Crofer 22H and nickel-chromium alloy Inconel 625 were thermally sprayed with MCO, and the oxidation, scale structure, and resistance of metallic substrates were investigated using XRD, TEM and SEM.
