I-Metal foam, njengohlobo olutsha lwezinto eziphathekayo, inoluhlu olubanzi kakhulu lwezicelo. Ngenxa yeempawu zayo, ayinayo kuphela ukunyanzeliswa okulungileyo kakhulu, kodwa ineplastiki enhle kakhulu kunye nokudibanisa; okwangoku, isetyenziswa ngokubanzi kwi-aerospace kunye nemimandla yasemkhosini, kwaye njengohlobo lwezinto zokwakha ezikhaphukhaphu, ikwasetyenziswa ngokubanzi kwiinkalo ezahlukeneyo zoshishino.

I-Aluminiyam i-foam yinto ebalaseleyo efumene ingqalelo ebanzi evela kumashishini ahlukeneyo ngenxa yeempawu zayo ezizodwa. Yinto ekhaphukhaphu enemibhobho eyenziwe nge-aluminiyam eqinileyo enenani elikhulu lee pores ezidibeneyo. Le nto intsha idibanisa amandla, ukuqina kunye nokuguquguquka, okwenza kube yinto efanelekileyo kwizicelo ezahlukeneyo.

Ehlabathini lezinto ezifunxa isandi, i-aluminiyam igwebu yenza amaza njengemveliso yoguquko. Ngeempawu zayo ezizodwa kunye nokuguquguquka, i-aluminiyam i-foam ivula indlela yokuphuhliswa kwezixhobo ezifunxa isandi ezichaza ngokutsha ishishini.

Ukuncipha kwamafutha efosili kunye neenkxalabo ezikhulayo malunga namandla kunye nemiba yokusingqongileyo kukhokelele kwiinzame zophando ezibanzi zokuphuhlisa eminye imithombo yamandla. I-electrochemical electrolysis yamanzi ithathwa njengesicwangciso esithembisayo sokuveliswa kwamafutha e-hydrogen.

Ngexesha lonxibelelwano olungenazingcingo oluya lusanda kunye nongcoliseko lwe-electromagnetic, imfuno yezixhobo zokufunxa amaza e-electromagnetic iye yabaluleke ngakumbi kunangaphambili. I-Metal foam, njengento entsha, ibonisa amandla amakhulu kule ntsimi. Uphando lwakutsha nje lugxile ekuphononongeni amandla e-electromagnetic wave of absorption of metal foams, kwaye iziphumo ziyamangalisa.

Kuluntu lwanamhlanje, sijongana nesithintelo esivakalayo le mveliso ngakumbi nangakumbi, iindibano zocweyo, izibhedlele, izikolo, iiofisi zolawulo lohola wendlela, njalo njalo imfuneko yokunciphisa ingxolo, kwinkqubo yokubonisana nayo, owona mbuzo ubuzwayo ngulo: njani kakhulu oku kunokuncitshiswa. Ngoku siza kubelana nawe ngomgaqo wokunciphisa ingxolo yesithintelo sesandi.

I-Aluminiyam i-foam yinto ephezulu yokusebenza elula, esetyenziswa ngokubanzi kwimveliso yeemoto, ukuhlobisa izakhiwo kunye nezinye iindawo. Ukuvelisa i-aluminium foam, kufuneka usebenzise uchungechunge lwezixhobo, kubandakanywa ukucutshungulwa, ukukhupha amagwebu, ukomisa kunye nezinye iinkqubo. Xa usebenzisa ezi zixhobo, nikela ingqalelo kukhuseleko, ulungelelanise kwaye ugcine izixhobo ngokwemiyalelo yokuqinisekisa umgangatho wemveliso kunye nokusebenza kakuhle kwe-foam ye-aluminium.

I-aluminiyam i-foam ifana ngokubunjwa kwesipontshi kwaye yaziwa ngokuba yintsimbi yendalo yonke, enoxinano oluphantsi kunye nobunzima obulula, esetyenziswa njengomaleko okhuselayo wezithuthi zasemkhathini, imelana noxinzelelo kwaye ikwazi ukumelana neempembelelo zombane ezibangelwa yimitha. Yimathiriyeli entsha yentsimbi eyenziwe ngengxubevange ye-aluminiyam enogwebu.

Njengezinto ezisetyenziswa ngokubanzi zokukhusela amandla, ukusetyenziswa kweepaneli ze-aluminium foam sandwich (AFS) zihlala zinyanzeliswa yimpahla ephantsi yomatshini we-foam core. Ukufakwa kwe-coppercoated carbon fibers (Cf) ibonakalise ukuba iyasebenza ekuphuculeni iimpawu zemishini ye-aluminium foam.

Nangona kunjalo, ukuqonda inkqubo yayo yogwebu kunye ne-microstructure kusenomda. Kulo msebenzi, i-AFS kunye ne-Cf/AFS zenziwe nge-packing rolling powder metallurgy method. Ukuziphatha okugwetyiweyo kwe-AFS kunye ne-Cf/AFS ngexesha lobushushu obunyusiweyo kwabonwa kusetyenziswa itekhnoloji ye-synchrotron yemitha ye-X-reyi yokujonga isiphumo se-Cf kwi-bubble nucleation, ukukhula, kunye nokuzinza kogwebu. Ngapha koko, i-macroscopic pore size distribution, microscopic microstructure, kunye necompressive mechanical properties ze-AFS kunye neCf/AFS zahlalutywa. Iziphumo zabonisa ukuba ubukho be-Cf bunyusa kakhulu izinga le-nucleation, kuphucula ukuzinza kogwebu, kwaye kuthintela ukubunjwa kwamaqamza amakhulu ngokungaqhelekanga ngexesha le-nucleation yokuqala kunye nenkqubo yokukhula. Ngeli xesha, i-Cf/AFS ibonise iidayimitha zepore ezintle kunye neziphene ezimbalwa kune-AFS. Ukusasazwa kwe-Cf kunye nokumanzi okugqwesileyo ecaleni kodonga lwepore kuthintele ukugqabhuka kwefilimu yolwelo kunye nokuncipha kokubambisana. Uvavanyo loxinzelelo lubonise ukuba, xa kuthelekiswa ne-AFS, amandla oxinzelelo kunye namandla okufunxa amandla e-Cf / AFS anyuke malunga ne-40.6% kunye ne-84.8%, ngokulandelanayo.

Iiphaneli ze-aluminium foam sandwich ziya zithandwa ngakumbi nangakumbi kumashishini ahlukeneyo ngenxa yeempawu zabo ezizodwa kunye noluhlu olubanzi lwezicelo. Ezi zixhobo zombane zibandakanya izinto ezingundoqo ezikhaphukhaphu (ezifana ne-aluminiyam yogwebu) ezifakwe phakathi kwamaphepha amabini abhityileyo e-aluminiyam. Olu lwakhiwo lutsha alunabunzima kuphela, kodwa lunamandla, luhlala luqinile kwaye lunokumelana nokugqwala. Kule bhlog, siza kujonga ngakumbi ukusetyenziswa kunye neenzuzo zeepaneli ze-aluminium foam sandwich, kunye nefuthe labo kumashishini ahlukeneyo.
