Ferritic Stainless Steels Coated a Dense La_(0.7)Sr_(0.3)CrO3 Layer as Interconnects for SOFCs

摘要

The La_(0.7)Sr_(0.3)CrO3 (LSC) powders were prepared using liquid-solid reaction method. The LSC ceramic layer was coated by plasma spraying on ferritic stainless steels to form a dense LSC film to resist high temperature oxidation corrosion. The results show the crystal phase of the coated layer is perovskite structure and the LSC coated layer is dense and the mass loss of the interconnects is 0.3 mg/cm~2 after heating at 850 °C for 60 h.
