Improved Oxidation Resistance And Cr Retention Of Coated AISI441 For SOC Application
Abstract
<title>Abstract</title><p>Durability is still a critical point, which limits Solid Oxide Cell (SOC) technology industrialization. In order to maintain a good level of performance for the overall targeted lifetime of about 40 kh, the oxidation of the interconnects made of ferritic stainless steel and Cr volatilization from this material to the cell electrodes have to be restricted. CeCo-based coatings were applied by PVD HiPIMS on AISI441 alloy. Their ability to reduce the thickness of the poorly conductive formed oxide and improve Cr retention was studied at sample scale by measurements of weight gain and Cr content by ICP-OES after 5 000 h of exposure in ambient air at 700 and 800°C. In the testing conditions, post-test characterization by SEM/EDX showed that oxide scale thickness was reduced when coatings were applied compared to bare AISI441 steel. Moreover, the strong oxide scale spallation observed at 800°C with bare AISI441 steel was avoided. Cr volatilization was also strongly decreased. Post-test SEM/EDX and ToF-SIMS characterization of a short stack integrating coatings on the air side in some repeat units (RU) confirmed the limited Cr diffusion in the strontium doped lanthanum manganite (LSM) contact layer when the coating is present after 5 200 h of solid oxide electrolysis cell operation (SOEC).</p>
