Degtyarev, V. Chukharev, T. Chashchukhina, L. Voronova, V. Vykhodets, T. Kurennykh] The degradation of the 10Kh23N18 steel structure with and without a protective Mn-Co-spinel coating after 8800 h of operation at 950°C is investigated as a switchgear material of a solid oxide fuel cell. Structural studies have shown no significant differences in the redistribution of alloying elements, in the composition and structure of oxide layers in the steel with and without the coating. The protective coating does not prevent the formation of silicon oxides and aluminum ones, which worsen the electrical conductivity of the switchgear and embrittle the material, in the surface layers of steel during long-term operation.
