Method of wet coating a ceramic substrate with a liquid suspension of metallic particles and binder applying similar dry metallic particles onto the wet surface, then drying and heat treating the article

摘要

A method for fabricating a liquid conducting porous article having micron sized metallic particles suspended on a ceramic substrate member. The method includes coating the ceramic substrate with a particle slurry on top of which is added an additional amount of the same particles as a dry powder, and then heat treating the article in a reducing gas atmosphere. The use of less than ten micron sized Nickel particles for the porous material and sintered fusion of the particles are also included.
