Ho fokotseha ha libeso le matšoenyeho a ntseng a eketseha ka matla le litaba tsa tikoloho li lebisitse boitekong bo batsi ba lipatlisiso ba ho hlahisa mehloli e meng ea matla. Electrochemical electrolysis ea metsi e nkoa e le leano le ts'episang bakeng sa tlhahiso ea mafura a hydrogen.

Mehleng ea likhokahano tse tebileng tsa mehala le tšilafalo ea motlakase, tlhoko ea lisebelisoa tse monyang maqhubu a motlakase e se e le bohlokoa ho feta leha e le neng pele. Metal foam, e le thepa e batlang e le ncha, e bontša bokhoni bo boholo tšimong ena. Lipatlisiso tsa morao-rao li tsepamisitse maikutlo ho lekola matla a ho monya maqhubu a motlakase a makukuno a tšepe, 'me liphetho li hlolla haholo.

Sechabeng sa kajeno, re buisana le thibelo ea molumo sehlahisoa sena se ntse se eketseha, lithupelo, lipetlele, likolo, liofisi tsa tsamaiso ea litsela tse kholo, joalo-joalo tlhokahalo ea ho fokotsa lerata, nakong ea ho buisana le eona, potso e atisang ho botsoa ke: joang? haholo sena se ka fokotsoa. Hona joale re tla arolelana le uena molao-motheo oa ho fokotsa lerata oa thibelo ea molumo.

Foam ea aluminium ke lisebelisoa tse bobebe tse sebetsang hantle, tse sebelisoang haholo ho etsa likoloi, ho khabisa meaho le masimong a mang. Ho hlahisa foam ea aluminium, o hloka ho sebelisa letoto la lisebelisoa, ho kenyelletsa ho sebetsa, ho foam, ho omisa le lits'ebetso tse ling. Ha u sebelisa lisebelisoa tsena, ela hloko polokeho, lokisa le ho boloka lisebelisoa ho latela litaelo ho netefatsa boleng ba tlhahiso le katleho ea ho sebetsa ha foam ea aluminium.

Foam ea aluminium e tšoana ka sebōpeho le seponche 'me e tsejoa e le tšepe ea bokahohle, e nang le boima bo tlaase le boima bo bobebe, e sebelisoang e le lera le sireletsang likoloi tsa sebaka, le hanyetsanang le khatello le ho khona ho mamella tšusumetso ea motlakase e bakoang ke mahlaseli. Ke thepa e ncha ea tšepe e entsoeng ka motsoako oa aluminium o foamed.

Joalo ka lisebelisoa tsa ts'ireletso tse monyang matla tse sebelisoang haholo, ts'ebeliso ea liphanele tsa aluminium foam sandwich (AFS) e ntse e hatelloa ke thepa e tlase ea mochini oa mantlha oa foam. Ho kenngoa ha li-coppercoated carbon fibers (Cf) ho ipakile ho sebetsa ho ntlafatsa thepa ea mochine ea foam ea aluminium.

Leha ho le joalo, kutloisiso ea ts'ebetso ea eona ea ho phophoma le ho hlaka ha eona e ntse e fokola. Mosebetsing ona, AFS le Cf/AFS li entsoe ka mokhoa oa ho pakela phofo oa metallurgy. Boitšoaro bo phophomang ba AFS le Cf/AFS nakong ea mocheso o phahameng bo ne bo bonoa ho sebelisoa theknoloji ea litšoantšo ea X-ray ea synchrotron ho fuputsa phello ea Cf ho bubble nucleation, kholo, le botsitso ba foam. Ho feta moo, kabo ea boholo ba pore ea macroscopic, sebopeho sa microscopic, le thepa e hatellang ea AFS le Cf/AFS e ile ea hlahlojoa. Liphello li bontšitse hore ho ba teng ha Cf haholo ho eketsa lebelo la nucleation, ho ntlafatsa botsitso ba ho foaming, le ho thibela ho thehoa ha li-bubble tse kholo ka mokhoa o sa tloaelehang nakong ea ts'ebetso ea pele ea nucleation le kgolo. Ho sa le joalo, Cf/AFS e bonts'itse li-diameter tse ntle haholo le liphoso tse fokolang tsa pore ho feta AFS. Kabo ea Cf e nang le mongobo o motle ka ho fetisisa leboteng la pore e ile ea thibela ho phatloha ha filimi ea metsi le ho fokotseha ha coalescence. Teko ea khatello e bontšitse hore, ha ho bapisoa le AFS, matla a khatello le matla a ho monya matla a Cf / AFS a eketsehile ka hoo e ka bang 40.6% le 84.8%, ka ho latellana.

Metal foam ke thepa ea tšepe e nang le thepa e khethehileng, e nang le thepa ea tšepe le ea foam, kahoo e bitsoa foam ea tšepe. Joale, na foam ea tšepe ke tšepe?

Na u tseba foam ea aluminium? Thepa ena e ncha e baka moferefere liindastering tse fapaneng ka lebaka la thepa ea eona e bobebe le e fapaneng. Ho blog ena, re tla shebisisa mefuta e fapaneng ea foam ea aluminium mme re hlahlobe mefuta e mengata ea lits'ebetso tsa bona.
