Abstract

Five metallic alloys, namely, Crofer22, equivalent ZMG232, stainless steel SS430, SS304 and Incone1718 were investigated. A La0.67Sr 0.33MnO3 (LSMO) thin film is coated on these materials using pulsed DC magnetron sputtering. The film is amorphous but transformed to perovskite structure after annealing at 600 °C, 700 °C, 800 □ and 900 □ for 1hr. The result shows the LSMO thin film on Crofer22 and equivalent ZMG232 were good for compaction and adhesion. Thus, it could prevent the growth of oxide and the diffusion of Cr element to avoid poison of the cathode and decline of conductivity in SOFC in high temperature.
