METHOD OF FORMING CATALYST STRUCTURE WITH CATALYST PARTICLES FORGED INTO SUBSTRATE SURFACE

摘要

A catalyst structure is formed by forging catalytic particles from a slurry into the surface of a metal substrate such that the particles protrude from the surface and are permanently fixed into the surface. The forging is accomplished by engaging rollers with the surface as it passes through the slurry to press the particles into the surface. The rollers may be brush rollers, fabric rollers or solid rollers. The particles may be any particles which have catalytic activity for a particular purpose and which are hard enough to forge into the metal substrate.
