Eyona nto intsha ishushu ngoku -Metal Foam
I-Metal foam inomlinganiselo othile wamandla, i-ductility kunye nokongeza, kwaye inokusetyenziswa njengento ekhaphukhaphu yesakhiwo. Isixhobo kudala sisetyenziswa njengesixhobo esiphambili sezixhobo zokubamba inqwelomoya. Kwimizi-mveliso ye-aerospace kunye ne-missile, isinyithi se-foam sisetyenziswa njengento ekhaphukhaphu, izakhiwo zokuxhasa ubushushu. Ngenxa yokuba inokuthi idityaniswe, idityaniswe okanye ifakwe kwisakhiwo, inokwenziwa ibe yi-sandwich ephethe imithwalo. Okufana neqokobhe lentsimbi yephiko lomzimba wenkxaso, i-missile yempumlo yegobolondo ye-anti-temperature yokuwa komzimba wenkxaso (ngenxa ye-conductivity enhle ye-thermal) kunye nesixhobo sokumisa i-spacecraft njalo njalo. Kulwakhiwo,igwebu lesinyithiiyadingeka ukwenza ukukhanya, ukuqina, izinto ezikwaziyo ukumelana nomlilo, iintsimbi okanye iqumrhu elixhasa ezi zinto. I-high-frequency, i-high-speed speed and deceleration of elevators zanamhlanje nazo zifuna izakhiwo ezikhaphukhaphu kunye neempawu zombini zokufunxa amandla kunye nomthwalo wokunciphisa ukusetyenziswa kwamandla. Amaqokobhe e-Cylindrical asetyenziswa ngokubanzi kwizakhiwo zobunjineli ezifana neefuselage zenqwelomoya kunye namaqonga e-oyile angekho elunxwemeni. Iigobolondo ze-cylindrical ezinqamlekileyo zonakaliswa ngokulula xa ziphantsi kwemithwalo, kodwa ukuba iqokobhe ixhaswa yi-foam eqhubekayo: i-coil, isakhiwo sinamandla amakhulu kuneqokobhe leziko elingaqiniswanga lobukhulu obufanayo kunye nobukhulu. I-foam ye-Copper kulula ukuyivelisa kwaye kulula ukuyikhubaza, iyenza ilungele ukusetyenziswa njengento yokuqinisa. Isinyithi se-foam sinokusetyenziswa njengento yokuqinisaimpahlaizinto ezininzi eziphilayo, inorganic kunye nentsimbi. Okufana ne-nickel foam egcwele i-aluminium etyhidiweyo yokuqina eyenziwe nge-nickel foam eqiniswe yi-aluminiyam alloy (NFRA) izinto.
Isinyithi se-Foam sikulungele kakhulu ukusetyenziswa njengeentlobo zeepaneli zokuthwala, iigobolondo kunye neetyhubhu ze-coil lightweight j, ezenziwe ngezinto ezahlukeneyo ezidibeneyo ezidibeneyo. Umzekelo oqhelekileyo wokusetyenziswa kwezixhobo ze-porous kumacandelo esakhiwo kukuveliswa kweepaneli zesandwich. Iiphaneli zesandwich ezisetyenziswa kwinqwelomoya yanamhlanje zisebenzisa iglasi okanye icarbon fiber composite isikhumba. Izikhumba zihlukaniswe nge-aluminium yensimbi okanye i-paper-resinizixhobo zobusi, okanye ngamagwebu epolymer aqinileyo, ukwenzela ukunika ipaneli yesandwich ukuqina okuthe ngqo kokugoba kunye namandla athile okugoba. Itekhnoloji efanayo iye yandiselwa kwinani lezinye izicelo apho ubunzima buyimetric ephambili: iishuttles zasemkhathini, iibhobhobhobho, iinqanawa zomdyarho, kunye nezakhiwo ezishukumayo, phakathi kwezinye.

Ukukhuselwa kwe-Cushioning kungenye yeendlela eziphambili zokusetyenziswa kwesinyithi se-foam, ekufuneka ibe namandla okufunxa amandla ngelixa igcina amandla aphezulu asebenza kwinto ekhuselweyo engaphantsi komda wokubangela umonakalo. Izinto eziphathekayo ze-foam zinokufaneleka kakuhle kwizicelo ezinjalo. Ngokulawula ukuxinana kwayo, amandla ensimbi ye-foam anokulungiswa kuluhlu olubanzi. Ukongeza, izinto eziphathekayo zinokumelana noxinzelelo olukhulu olucinezelayo phantsi koxinzelelo oluthe rhoqo, ukwenzela ukuba umthamo omkhulu wamandla ufunxwe ngaphandle koxinzelelo oluphezulu. Ekulungiseleleni amathambo okufakelwa, ngokweemfuno zobungakanani bepore ye-150¨m ~ 250¨m kunye ne-porosity enkulu, izinto ezingaphiliyo ngenxa yamandla eli xesha azikwazi ukuhlangabezana neemfuno zokusetyenziswa, kwaye ngokuthe ngcembe ziphuhliswe zibe yi-iron.igwebu lesinyithiithambo elenziweyo. Ezi zinyithi zegwebu ziveliswa ngeendlela eziqhelekileyo ezifana ne-electroplating, kwaye ziphantsi kwemithwalo ngexesha lokubumba kunye nezinye iinkqubo kunye nomzimba womntu. Kubaluleke kakhulu kwizinto ezininzi zamathambo abantu abangenayo impembelelo yokuzibuyisela ukuze baqonde i-porosity enkulu efunekayo kwithambo lomntu ngelixa igcina iipropathi eziphezulu zoomatshini, oko kukuthi, ukuhlangabezana ne-porosity enkulu efunekayo kwithambo lomntu ngelixa ugcina iimpawu eziphezulu zoomatshini.
