Abstract: A method of fabrication of porous metal structures as applicable to the manufacture of supports for electrodes, catalysts, filters or sound insulators. A porous structure is fabricated from a support consisting of a felt, a woven or reticulated structure in accordance with the following steps:(a) initial metallization of the support;(b) chemical and/or electrochemical metallization if so required;(c) removal of the support if necessary.The distinctive feature of the invention lies in the fact that the initial metallization step consists of metallization in vacuum.
