Abstract

Disclosed is a method for producing a metal or ceramic component having regions of differing porosities. The method includes subjecting powder or a presintered precursor to a pressure-assisted pressing and sintering step, using at least one punch for the pressing step. The at least one punch has a contact surface that is intended for making contact with the powder or the presintered precursor and that has a flat outer region and an inner region having a concave recess. After the sintering step, a component is obtained that has a flat outer compacted region having a first porosity and an inner porous region having a second porosity. The component has, on at least one side, a defined transition region between the outer region and the inner region.
