I-Metal Foam - insimbi ephefumulayo

Ngenxa yesakhiwo sayo esikhethekile, inezindawo ezikhethekile ezicini eziningi. Njengempahla yesakhiwo, ibonakala ngesisindo esincane namandla athile aphezulu; njengento esebenzayo, inezinhlobonhlobo zezinto ezibonakalayo ezifana ne-porous, i-vibration damping, i-damping, i-sound-absorbeng, i-insulation yomsindo, ukuchithwa kokushisa, ukumuncwa kwamandla okunomthelela, ukuvikela i-electromagnetic nokunye.
Insimbi ye-Foamilungiswa ngendlela ye-powder metallurgy kanye nendlela ye-electroplating, eyokuqala ngokungeza i-ejenti egwebuzelayo ensimbi encibilikisiwe ukuze ikhiqize insimbi yegwebu; Eyokugcina ngenqubo ye-electrodeposition kuhlaka lwamathambo oluyigwebu le-polyurethane oluphindiselwe ensimbi yegwebu.
Indlela ye-powder metallurgy yokwenza i-foam metal, yengezwa ku-ejenti ephephetha impushana (efana ne-NH4Cl), i-sintering i-ejenti evuthelayo ivuvukale, ishiye izimbotshana. Izinsimbi zegwebu ezinezimbotshana ezimise okwejwayelekile kanye ne-porosity efinyelela ku-95% ingenziwa ngokufakwa kwe-electrochemical, kufaka phakathi izinto zegwebu ezinezinsimbi nama-alloys njengeCu, Ni, NiCrFe, ZnCu, NiCu, NiCrW, NiFe, nezinye izinsimbi nama-alloys njenge-alloys. uhlaka lwamathambo. I-electrochemically yensimbi efakwe emzimbeni onezimbotshana i-sintered ukuze izingxenye ezifakiwe zixhunywe zizonke, futhi amandla afinyelela ensimbi edingekayo enegwebu elinezimbotshana ezine-porosity ephezulu, engagcwaliswa ngezinto eziningi njengama-catalyst nama-electrolyte sebenzisa.
I-aluminium, i-nickel kanye nama-alloys abo bekuyinsimbi ye-foam esebenzayo, ngaphezu kwalokho, ithusi le-foam libuye libe nendawo ethile yokuthuthukiswa.
I-aluminium Foamkanye nama-alloys ayo ayisindi, anokumuncwa komsindo, ukufakwa kokushisa, ukuncibilika kokudlidliza, ukumuncwa kwamandla okuthinta kanye namagagasi kagesi nezinye izici, alungele imicibisholo ecitshwayo, izindiza kanye nezingxenye zayo zokubuyisela umthelela wesendlalelo esivikelayo, amabhafa ezimoto, ukudlidliza kwemishini kagesi. amadivaysi okudambisa, i-pulse power electromagnetic wave shielding cover.
Igwebu le-nickelinokungena kwegesi ephezulu, indawo ethile ephezulu kanye namandla e-capillary ngenxa yesakhiwo sayo se-pore esixhunyiwe kanye ne-porosity ephezulu, futhi isetshenziswa kakhulu njengento esebenzayo yokwenza izihlungi zoketshezi, ama-atomizer, ama-catalytic converters, amapuleti e-electrode ebhethri kanye nezishintshi zokushisa.
Igwebu lethusiconductivity kanye ductility kuhle, futhi izindleko ukulungiselela iphansi kune-nickel Foam, conductivity kangcono, ingasetshenziswa ukulungiselela ibhethri negative electrode (isithwali) materials, catalyst abathwali kanye electromagnetic shielding materials. Ikakhulukazi, igwebu lethusi lamabhethri njengezinto ze-electrode substrate, linezinzuzo ezithile ezisobala, kodwa ngenxa yokumelana nokugqwala kwethusi akukuhle njenge-nickel, ngaleyo ndlela futhi kukhawulele ezinye zezicelo zayo.
Lesi sici sekuyisikhathi eside sisetshenziswa njengento eyinhloko yezingxenye zokubopha izindiza. Embonini ye-aerospace kanye ne-missile, ingenziwa ibe izingxenye ezithwala isangweji, njengegobolondo lensimbi ephiko lomzimba osekelayo, i-missile yekhala yegobolondo lokuwa kwezinga lokushisa eliphezulu lomzimba wokusekela (ngenxa yokushisa kwayo okuhle. conductivity) kanye negiya lokumisa lendizamkhathi. Ekwakhiweni, insimbi yegwebu iyadingeka ukwenza izinto ezilula, eziqinile, ezikwazi ukumelana nomlilo, izinsimbi noma izinhlangano ezisekela lezi zinto. I-high-frequency, isivinini esiphezulu kanye nokwehliswa kwejubane kwamakheshi esimanje nakho kudinga izakhiwo ezingasindi ezinakho kokubili ukumunca amandla kanye nezakhiwo ezithwala umthwalo ukuze kuncishiswe ukusetshenziswa kwamandla. I-Cushioning ingenye yezindlela eziyinhloko ezisetshenziswa ngayo i-foam metal, okumele ibe nekhono lokumunca amandla ngenkathi igcina amandla amakhulu asebenza entweni evikelwe ngaphansi komkhawulo wokudala umonakalo.
