An improved apparatus and method of producing metal foam is provided which involves optimizing the natural convection of electrolyte through a foam being electroplated by inclining the foam during plating. A diagonal flow of electrolyte though the foam enhances electrolyte turnover within the foam while increasing electroplating efficiency. Further increases in plating efficiency are provided by shifting current density from higher plating zones to lower plating zones.
La présente invention concerne un appareil amélioré et un procédé de production de mousse métallique qui implique l'optimisation de la convection naturelle d'un électrolyte à travers une mousse subissant une électrodéposition en inclinant la mousse pendant la déposition. Un flux diagonal d'électrolyte à travers la mousse améliore le rendement de l'électrolyte à travers la mousse tout en augmentant l'efficacité de déposition. L'efficacité de déposition est encore améliorée si l'on décale la densité de courant depuis les zones de déposition supérieures vers les zones de déposition inférieures.
