Kukonzekera kwa Aluminiyamu Foam ndi Kugawa Kwamtundu Wamakutu Aang'ono a Pore ndi Novel Composite Foaming Agent

Zitsulo thovu, makamakaaluminium thovu, amagwiritsidwa ntchito kwambiri m'munda wazinthu. Njira yosungunula thovu yakhala ikugwiritsidwa ntchito kwambiri popanga mafakitale chifukwa chokonzekera bwino komanso kukhazikika kwazinthu. Ngakhale kuti kugwirizana kwenikweni pakati pa katundu ndi mapangidwe a pore sikunamvetsetsedwe bwino, zithovu zogawidwa mofanana ndi kukula kwa pore ndi zolakwika zochepa nthawi zonse zimakhala zofunika kwambiri.

Panopa, pore kukula ndi dongosolo lazitsulo za aluminiyamuzimakhala zovuta kuzilamulira panthawi yosungunula thovu, ndipo zimakhala zovuta kupanga thovu za aluminiyamu zokhala ndi ma pore ang'onoang'ono, makamaka chifukwa cha kuwola koyambirira komanso kubalalitsidwa koyipa kwa chowombera (nthawi zambiri TiH2). Potengera izi, gulu la Prof. Yanxiang Li pa yunivesite ya Tsinghua anaphunzira ndondomeko pre-kubalalitsidwa kwa TiH2 mu kusungunula AlMg35 wapakatikati aloyi pambuyo makutidwe ndi okosijeni mankhwala, amene angathe kumaliza kubalalitsidwa popanda kuvunda, ndipo analenga latsopano AlMg35-TiH2. kompositi thovu wothandizira. Zotsatira za nthawi yosonkhezera ndi kuombera kwa wothandizila pamtundu wa thovu lolingana ndi aluminiyamu zidawunikidwanso. Zotsatira za kafukufukuyu zidasindikizidwa mu nyuzipepala "Journal of Materials Processing Technology" yokhala ndi mutu wakuti "Kukula kwa gulu la AlMg35-TiH2 lopanga thovu komanso kupanga thovu laling'ono la aluminium". Journal of Materials Processing Technology.Zida za aluminiyamuzokonzedwa ndi gulu lopangidwa thovu wothandizila yodziwika ndi dongosolo bwino, yaing'ono pore kukula, yunifolomu pore kugawa ndi ozungulira pore mawonekedwe. Kuwongolera kwa njirayi ndikuti tinthu ta TiH2 timamwazikana m'malo otsika osungunuka aloyi amasungunuka ndi nthawi yayitali yoyambitsa ndipo sizovuta kuwola.

Wowombayo adakwanitsa kukonza ma cell ang'onoang'ono ang'onoang'ono okhala ndi thovu la aluminiyamu yokhala ndi pore yochepera 0.6 mm, yomwe makamaka idachitika chifukwa chakuchedwa kutha kwa nthawi ya TiH2 chifukwa chamankhwala a pre-oxidation ndi AlMg35 yomwe idayikidwamo. , zomwe zinapangitsa kuti nthawi yoyambitsayi ikhale yopiririka. The chisanadze oxidized TiH2 particles anali omwazika mu madzi AlMg35 aloyi, kupangitsa kukhala kosavuta kumwazikana ndi TiH2 particles mu zotayidwa kusungunula ndi zochepa tinthu aggregation. Kuphatikiza apo, njirayi imachepetsa kuchuluka kwa TiH2 yomwe imawonjezeredwa pochita thovu, yomwe imakhala yotsika mtengo komanso yoyenera.kupanga mafakitale.
