Metal foam classifications

Metal Foam haholo-holo e le foam ea aluminium, foam ea koporo, foam ea nickel le tse ling tsa alloys foam.

Foam ea aluminium e nang le li-alloys e bobebe ka boima ba 'mele ebile e na le litšoaneleho tsa ho monya molumo, ho kenya mocheso, ho fokotsa ho sisinyeha, ho monya matla le maqhubu a motlakase, joalo-joalo. sesebelisoa sa ho fokotsa li-electromechanical vibration, sekoaelo sa motlakase oa motlakase oa motlakase oa pulse, joalo-joalo.

Ka lebaka la sebopeho sa pore se hokahaneng le porosity e phahameng, foam ea nickel e na le ts'ebetso e phahameng ea khase, sebaka se phahameng se ikhethileng le matla a capillary. Hangata e sebelisoa e le lisebelisoa tse sebetsang ho etsa li-filters tsa mokelikeli, liathomo, li-catalytic converters, lipoleiti tsa betri le li-ex-changer tsa mocheso.

Foam ea koporo e na le conductivity e ntle le ductility, theko e tlase ea ho itokisa ho feta foam ea nickel, le conductivity e betere, kahoo e ka sebelisoa ho lokiseng lisebelisoa tsa anode (carrier) ea betri, li-catalyst carriers le lisebelisoa tsa tšireletso ea motlakase.

Ka ho khetheha, foam ea koporo e sebelisoa e le thepa ea motheo ea electrode ea betri, e nang le melemo e totobetseng. Leha ho le joalo, khanyetso ea koporo ha e ntle joaloka nickel, e fokotsang tšebeliso ea eona.

Lisebelisoa tsa foam tsa tšepe

Metal foams e na le matla a itseng, ductility le addability, 'me e ka sebelisoa e le lisebelisoa tse bobebe tsa mohaho.Sesebelisoa sena ke khale se sebelisoa e le lisebelisoa tsa motheo bakeng sa likotoana tsa lifofane meaho ea ts'ehetso.Hobane e ka tšelisoa, ea khomaretsoa kapa ea kenngoa ka motlakase holim'a sebopeho, e ka etsoa hore e be setho sa sandwich se nang le setho. khetla ea tšepe ea lepheo, ts'ehetso e khahlanong le ho oa bakeng sa nko ea motsu (ka lebaka la conductivity ea eona e ntle ea mocheso) le lisebelisoa tsa ho lulisa tsa sepakapaka, joalo-joalo.
