Abstract: The invention relates to a method for producing metallic moulded bodies comprising a ceramic layer according to the membrane method, whereby a porous metallic membrane is used. The aim of the invention is to provide a cost-effective, rapid method which is as non-polluting as possible for producing metallic moulded bodies comprising a ceramic layer according to the membrane method using a porous metallic membrane, whereby the penetration depth, the green density and the deposition speed of the ceramic particles in the metallic membrane can be controlled. To this end, the porous metallic membrane is sealed by electrophoretic deposition of ceramic particles in the pores of the metallic membrane, the metallic membrane being arranged between two electrodes for the electrophoretic deposition, and the space between an electrode and the metallic membrane being filled with a dispersion containing the ceramic particles to be deposited in the pores and a dispersant.
