Metal Foam - tšepe e phefumolohang

Ka lebaka la sebopeho sa eona se khethehileng, se na le thepa e khethehileng likarolong tse ngata. E le thepa ea mohaho, e khetholloa ke boima bo bobebe le matla a khethehileng a phahameng; e le thepa e sebetsang, e na le mefuta e fapaneng ea thepa ea 'mele e kang porous, vibration damping, damping, sound-absorbent, sound insulation, dissipation heat, impact absorption, electromagnetic shielding joalo-joalo.
Foam tšepee lokisoa ka mokhoa oa metallurgy oa phofo le mokhoa oa electroplating, oa pele ka ho eketsa ntho e phophomang ka tšepe e qhibilihisitsoeng ho hlahisa tšepe ea foam; ea morao-rao ka ts'ebetso ea electrodeposition holim'a skeleton ea foam ea polyurethane e entsoeng ka tšepe ea foam.
Powder metallurgy mokhoa oa ho etsa foam tšepe, e ekeletsoa ho phofo foka moemeli (joaloka NH4Cl), sintering e fokang moemeli volatilization, siea pores. Lisebelisoa tsa foam tse nang le li-pores tse bōpehileng ka mehla le porosity e phahameng ho 95% e ka etsoa ka ho kenngoa ha electrochemical, ho kenyelletsa le lisebelisoa tsa foam tse nang le tšepe le li-alloys tse kang Cu, Ni, NiCrFe, ZnCu, NiCu, NiCrW, NiFe, le lisebelisoa tse ling le li-alloys. skeleton. The tšepe electrochemically beha ka 'mele porous e sintered e le hore likarolo tse behiloeng li amana ka kakaretso,' me matla a ho fihlela ho hlokahala haholo porous foam tšepe le porosity phahameng, e ka tlatsoa ka lintho tse ngata tse kang catalysts le electrolyte ka. tshebediso.
Aluminium, nickel le li-alloys tsa bona e bile tšepe e sebetsang ea foam, ho phaella moo, koporo ea foam e boetse e na le sebaka se itseng sa tsoelo-pele.
Foam aluminium'me li-alloys tsa eona li bobebe, li na le molumo oa molumo, mocheso oa mocheso, mocheso oa ho sisinyeha, ho monya matla a matla le maqhubu a motlakase le litšobotsi tse ling, tse loketseng metsu, lifofane le likarolo tsa eona tsa ho tsosolosa phello ea lera le sireletsang, li-buffers tsa likoloi, mochine oa elektroniki oa vibration. lisebelisoa tse futhumatsang, sekoaelo sa pulse power electromagnetic wave shielding.
Nickel foame na le matla a phahameng a khase, sebaka se phahameng se phahameng le matla a capillary ka lebaka la sebopeho sa eona se kopantsoeng sa pore le porosity e phahameng, 'me hangata e sebelisoa e le lisebelisoa tse sebetsang bakeng sa ho etsa li-filters tsa mokelikeli, li-atomizer, li-converter tsa catalytic, lipoleiti tsa electrode tsa betri le mocheso oa mocheso.
Foam ea koporoconductivity le ductility e ntle, 'me litšenyehelo tsa ho lokisetsa li tlase ho feta foam ea nickel, conductivity e ntle, e ka sebelisoa bakeng sa ho lokisa lisebelisoa tsa li-electrode tse mpe (mojari), li-catalyst carriers le lisebelisoa tsa tšireletso ea motlakase. Ka ho khetheha, foam ea koporo bakeng sa libeteri e le lisebelisoa tsa electrode substrate, e na le melemo e meng e totobetseng, empa ka lebaka la ho hanyetsa ha koporo ha e ntle joaloka nickel, kahoo e boetse e fokotsa tse ling tsa lisebelisoa tsa eona.
Boitsebiso bona esale bo sebelisoa e le lisebelisoa tsa mantlha bakeng sa likarolo tsa ho koala sefofane. Lefapheng la lifofane le indasteri ea limisaele, e ka etsoa ka likaroloana tse nang le sandwich, joalo ka khetla ea tšepe ea mapheo ea 'mele oa tšehetso, khoune ea nko ea khetla ea ho putlama ha mocheso o phahameng oa' mele oa tšehetso (ka lebaka la mocheso oa eona o motle. conductivity) le lisebelisoa tse thellang tsa sefofa-sebakeng. Kahong, tšepe ea foam e ea hlokahala ho etsa lisebelisoa tse bobebe, tse thata, tse sa cheng, litšepe kapa mekhatlo e tšehetsang lintho tsena. Maqhubu a phahameng, ho potlakisa le ho fokotseha ha li-elevator tsa sejoale-joale ho boetse ho hloka hore ho be le meaho e bobebe e nang le thepa ea ho monya matla le e tsamaisang thepa ho fokotsa tšebeliso ea matla. Cushioning e boetse e le e 'ngoe ea lisebelisoa tse ka sehloohong tsa tšepe ea foam, e lokelang ho ba le bokhoni ba ho monya matla ha e ntse e boloka matla a mangata a sebetsang ho ntho e sirelelitsoeng ka tlase ho moeli oa ho baka tšenyo.
