Yintoni iarhente yogwebu lwealuminium?

Kukho iindlela ezahlukeneyo eziphambili zei-aluminiyam yogwebu, kubandakanywa indlela yokunyibilika kwegwebu, indlela yomgubo wesinyithi wesinyithi kunye nendlela yokwesibini yogwebu.
Indlela yokunyibilika kwegwebu yindlela yokuvelisa ulwelo lwe-aluminiyam yolwelo. Inkqubo ethile yokongeza i-agent ekhulayo ye-viscosity, efana ne-silicon carbide okanye i-alumina, kulwelo lwe-aluminiyam etyhidiweyo ukuze kwandiswe i-viscosity yolwelo lwe-aluminiyam kwaye ithintele amaqamza ekunyukeni nasekudibaniseni ngokukhawuleza okukhulu. Emva koko, i-agent ephosa ugwebu, efana ne-titanium hydride okanye i-hydrogen zirconium hydride, yongezwa kwi-aluminium engamanzi, kwaye ezi zixhobo ezinogwebu zibola kumaqondo obushushu aphezulu ukuvelisa iigesi ezibangela ukuba i-aluminiyam engamanzi yande kunye negwebu. Ngokulawula ubungakanani bearhente yokuvuthela eyongeziweyo, iqondo lobushushu lokubola kunye ne-viscosity yolwelo lwe-aluminium, ubungakanani kunye nokuhanjiswa kwamaqamu erhasi kunokulungelelaniswa, nto leyo ekhokelela ekubeniugwebu aluminiyamngesakhiwo esifunwayo. Emva kokupholisa kunye nokuqina, i-cell evaliweyo okanye i-open-cell aluminium foam material yenziwe.
Indlela yomgubo we-metallurgy kukulungisa amagwebu e-aluminiyam ngesiseko somgubo oqinileyo we-aluminium. Okokuqala, i-aluminium powder ixutywe kunye ne-agent evuthelayo kwaye icinezele phantsi koxinzelelo oluthile ukwenza ibhloko edibeneyo edibeneyo. Emva koko, iibhloko ezenziwe ngaphambili zifakwe kwisithando somlilo kwaye zifudunyezwe ukuvala indawo yokunyibilika kwe-aluminium, ngelo xesha i-agent evuthelayo iqala ukubola, kwaye igesi eveliswayo ibangela ukuba iibhloko ezifakwe ngaphambili zandise ukwenza isakhiwo se-porous. Ngokulungelelanisa ubushushu obugwebu, ixesha kunye noxinaniso lweebhloko ezenziwe ngaphambili, i-porosity kunye nesakhiwo se-poreugwebu aluminiyaminokulawulwa. Indlela yokugaya i-metallurgy ilungele ukulungiselela iimveliso ze-aluminiyam ezinemilo enzima kunye neemfuno eziphezulu ze-porosity.
Indlela yesibini yogwebu idibanisa iingenelo zendlela yokunyibilika kwegwebu kunye nemethodi yomgubo wesinyithi. Okokuqala yongeza i-agent ekhulayo ye-viscosity kunye ne-arhente ekhupha ugwebu kwi-aluminium enyibilikayo, ixube kakuhle kwaye iphosa kwi-mold yokupholisa ngokukhawuleza kunye nokuqina ukuze ufumane isandulela esinogwebu. Xa i-precursor ifudumala kwiqondo lokushisa elithile, i-agent agent iqala ukubola kunye ne-foam, kwaye ekugqibeleni ivelise i-aluminium foam. Le ndlela inokulawula ngcono ubume bepore kunye neepropathi ze-aluminiyam ugwebu ngokusebenzisa amanyathelo amabini ogwebu, kwaye ifanelekile ukulungiselela ukusebenza okuphezulu.ugwebu aluminiyamizixhobo.
Kukho iindlela ezahlukeneyo ze-aluminiyam yogwebu, kwaye indlela nganye ineempawu zayo ezizodwa kunye nobubanzi bokusetyenziswa. Kwisicelo esisebenzayo, indlela efanelekileyo inokukhethwa ngokweemfuno ezithile kunye neemeko zokulungiswa kwe-foam ye-aluminium.
