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 invention also relates to a metallic moulded body comprising a ceramic layer and to the use of one such metallic moulded body. 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 he 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.
Method for producing metallic formed articles with a ceramic layer by the membrane method, using a porous metallic membrane, Method for producing metallic formed articles with a ceramic layer by the membrane method, using a porous metallic membrane, wherein the porous metallic membrane is post-densified by electrophoretic deposition of ceramic particles in the pores of the metallic membrane, and that the metallic membrane is placed between two electrodes for the electrophoretic deposition, and the space between one electrode and the face of the metallic membrane is filled with a dispersion that contains the ceramic particles to be deposited in the pores and a dispersant.
