Influence of Post-Treatment on the Performances of Plasma Spraying La_(0.8)Sr_(0.2)CrO3 Coating Layer on Ferritic Stainless Steel as Interconnects for Solid Oxide Fuel Cells

摘要

The La_(0.8)Sr_(0.2)CrO3 (LSC) coating layer prepared by plasma spraying is an effective means of providing oxidation resistance of ferrite stainless steel as interconnects for solid oxide fuel cells. The results show that a denser coating layer is acquired and the area specific resi stances (ASRs) of the LSC coating layer and LSC coating layer modified by post-treatment are 0.18 and 0.015 Ω cm~2, respectively, at 800 °C after oxidation at 1200 °C for 20 h, indicating the oxidation resistances of the modified LSC coating layer is significantly improved,
