FIELD: metallurgy; production of reticular nickel structures from metallized foamed plastics used as bases in manufacture of storage batteries, filtering materials or catalyst carriers.
SUBSTANCE: proposed method includes heating of starting nickel-plated polymer for removal of polymer substrate and decarbonization of nickel for obtaining nickel structure followed by annealing of nickel structure. Thermochemical treatment of nickel-plated polymer structures is performed in two zones at different atmospheres. Heating of starting nickel-plated polymer in first zone is performed for removal of polymer substrate and decarbonization of nickel at obtaining nickel structure in oxidizing/reducing atmosphere at temperature of 900-1300°C for at least 3 s. In second zone, nickel structure is subjected to annealing in reducing atmosphere at temperature of 800-1100°C.
EFFECT: possibility of production of foamed nickel of preset chemical composition and mechanical properties.
