  • Method for producing a porous metallic or ceramic component and component produced using the method
    Patent number: 12617733
    Abstract: An open-pored polymeric foam body is provided with a metallic coating or a coating at the surfaces of struts of the foam body. At the semi-finished product, a suspension that is formed with metallic or ceramic particles, in which additionally gas bubbles are present, is brought in contact with the surface of the foam body in surface regions and is brought into a predefined shape. A portion of this suspension penetrates into open pores of the foam body. Thereafter, a thermal treatment is carried out, during which liquid is expelled, polymeric components are removed, and subsequently a sintering process is carried out. A first volume region is formed with the metal or the ceramic originating from the suspension, which has a smaller porosity. Adjoining this first volume region, a second volume region is created, which is likewise porous.
