abstract = {Thin-film La0.58Sr0.4Co0.2Fe0.8O3−δ (LSCF58428) exhibits
high oxygen permeability due to its high ionic and
electronic conductivity. In order to increase the oxygen
flux, a thin-film membrane on a structural substrate is
beneficial. Different Ni-based alloys were studied as
potential substrate materials. The chemical compositions and
thermal expansion coefficients of Ni-based alloys were
measured in this study. LSCF58428 layers were screen printed
on Ni-based alloys and cofired at a high temperature in air.
Microstructural and elemental analyses of samples were
conducted using a scanning electron microscope and
energy-dispersive X-ray spectroscope. X-ray diffraction was
used to investigate the phase compositions. The Ni-based
alloy, MCrAlY (with M=Ni, Co), with a high Al content showed
better chemical compatibility with perovskite material at
high temperatures than other Ni-based alloys. A reaction
occurred between Sr in the perovskite and the alumina-based
surface layer on MCrAlY. However, the reaction zone was
found to be stable in mid-term annealing at 800°C in air.
Hence, it is expected that this reaction will not prevent
application as an oxygen transport membrane. Three different
cofiring atmospheres were investigated. Air was found to be
the only possible cofiring atmosphere.},
