An environmentally friendly process for producing metal biporous foam by using filamentary metal powders such as nickel or copper. The filamentary metal powders are initially wet when combined with a suitable foam former such as methylcellulose. Because the filamentary metal powder is wet, it does not extract water from the foam structure thereby ensuring a highly porous metal foam having both high macroporosity and microporosity.
L~invention concerne un procédé écologique de fabrication d~une mousse métallique biporeuse utilisant des poudres métalliques filamenteuses telles que du nickel ou du cuivre. Les poudres métalliques filamenteuses sont initialement humides lors de leur mélange avec un agent moussant approprié tel que la méthylcellulose. La poudre métallique filamenteuse étant humide, elle n~extrait pas l~eau de la structure mousseuse, permettant ainsi d~obtenir une mousse métallique de grande porosité présentant à la fois une grande macroporosité et une grande microporosité.
