Ceria-yttria stabilized zirconia (CYSZ) coatings were prepared by air plasma-sprayed on the nickel alloy. The as-sprayed CYSZ coatings and heat-treated CYSZ coatings were characterized by X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD). The XPS data indicated the coexistence of Ce
of Ti to a few percent. Pre-evaporation of a 300 ,~ thick CaF.~ parting layer allowed membrane removal by water-assisted peeling. Pressure testing showed membranes to have bulk tensile strength of 4.6-6.2,'< l09 dyn/cm 2 (68-92 kpsi) and to behave elastically. They could be mounted under high tensio
