Abstract:
A method for sintering a porous coating on an open-structure substrate comprising the steps of:selecting an open-structure substrate with openings of desired sizes, said open-structure substrate having a first side and a second side; admixing a coating material with a binder to form a paste having a viscosity high enough to prevent said paste from dripping through the openings on the open-structure substrate, wherein the coating material is non-conductive; applying the paste to the first side of said open-structure substrate to form a paste layer of a desired thickness; heating the paste layer at a sintering temperature for a period of time to form a porous coating on the open-structure substrate; pre-coating the non-conductive coating material with a conductive material by electroless plating or atomic layer deposition; and depositing a catalyst on the pre-coated non-conductive coating material by electroplating, electroless plating, or atomic layer deposition.
