PLASMA SPRAYED OXYGEN TRANSPORT MEMBRANE

摘要

PROBLEM TO BE SOLVED: To form oxygen and hydrogen transport membranes by plasma spray deposition on a substrate, to disclose a multi-layer composite comprising a porous substrate and membranes provided by supersonic plasma spray deposition and to form a crack-free oxygen transport membrane on a substrate by plasma spray deposition of single phase or dual phase nanocrystalline particles.

SOLUTION: The ion or electron or ion mixture and electron conductive membrane is fabricated by a method including spraying of a single phase or dual phase composition from a plasma torch or plasma gun at a supersonic velocity in the presence of an inert gas as a plasma medium and coating the surface of the porous or dense substrate with the composition in order to provide the surface of the substrate with the oxygen transport member in the shape of a ceramic coating free of micro-cracks.
