(FR) PRODUITS EN MOUSSE D'ALUMINIUM RESISTANTS A LA CORROSION
Abstract
(EN) An aluminum foam product that exhibits superior resistance to corrosion and oxidation in aqueous environments. The invention comprises the incorporation of chemical buffering agents, such as anhydrous borax (Na2B4O7), into the formulation of aluminum foam in amounts that effectively reduce the corrosion and oxidation in aqueous environments.
