CREATION METHOD OF POROUS COATING ON METAL ELECTRICALLY CONDUCTING CARRIER Russian patent published in 2013 - IPC H01M4/04 

FIELD: metallurgy.

SUBSTANCE: in a creation method of porous material, on electrically conducting metal carrier there formed for the purpose of increasing specific surface and porosity is a catalytic active layer on metal carrier by means of high-energy processes of gas-phase transfer, and namely by microplasma or cold gas-dynamic sputtering of composite powder mixture consisting of metal powder-base and pore agent; with that, the obtained coating as a result of sputtering is subject to heat treatment at the temperature of decomposition of pore agent into solid-phase and steam-gas components; as a result, gaseous component is removed through the coating, thus forming through pores, and solid-phase component is deposited on walls of pores, thus considerably increasing an integral specific coating surface.

EFFECT: production of high-efficiency porous material on metal carrier with high specific surface and porosity.
