Abstract
The present invention relates to a process for producing a sintered porous metal plate comprising metal particles directly and integrally bonded together due to sintering, the plate being of porous construction and having a density gradient in the direction of thickness, comprising charging metal particles into a refractory mold, pressing the particles, passing an electric current therethrough to heat the metal particles approximately up to their transformation point and then heating the metal particles to effect sintering.
