Abstract (en)
[origin: CA3076513A1] The invention relates to a method for producing open-pore molded bodies which have a modified surface and which are made of a metal. The surface of an open-pore molded body which is made of a metal, said molded body being used as a semi-finished product, is coated with particles of a chemical compound of a metal which can be reduced or thermally or chemically decomposed in a thermal treatment, and particles of the respective metal are produced by means of the thermal treatment, said particles being obtained by means of a chemical reduction or a thermal or chemical decomposition. After the coating process, at least one thermal treatment is carried out, in which the produced metal particles are connected to the surface of the semi-finished product and/or adjacent produced particles via sintered necks or sintered bridges such that the specific surface area of the obtained open-pore molded body is increased to at least 30 m /l and/or at least by a factor of 5 in comparison to the starting material of the uncoated metal semi-finished product.
