Abstract
A method of preparing the surface of a porous metal substrate to receive a membrane. The method does not substantially decrease the average bulk porosity of the metal substrate. A hydrogen separation membrane supported on the porous metal substrate. A cold spray is used to reduce surface variance. Exposure to an ion beam may also be used after application on the cold spray to prepare the surface of the substrate for membrane deposition.
