Nikolai Kakhidze, seithuti se fumaneng mangolo Lefapheng la Fisiks le Boenjiniere, o khothalelitse ho sebelisa daemane kapa aluminium oxide nanoparticles e le sebaka se seng sa scandium e theko e boima bakeng sa ho thatafatsa li-alloys tsa aluminium.Thepa e ncha e tla bitsa makhetlo a 4 ka tlase ho analoge e nang le scandium e nang le thepa e haufi ea 'mele le ea mochini.
Hajoale, lik'hamphani tse ngata tse hahang likepe li leka ka matla ho nkela tšepe e boima sebaka ka lisebelisoa tse bobebe le tse bobebe haholo.Ntle le ho eketsa bokhoni ba ho jara, sena se ka sebelisoa hantle ho fokotsa tšebeliso ea mafura, ho fokotsa mesi e kotsi sepakapakeng le ho eketsa motsamao oa sekepe le ho potlakisa phano ea thepa.Likhoebo tse indastering ea lipalangoang le tsa sefofane le tsona li thahasella lisebelisoa tse ncha.
Lisebelisoa tse kopantsoeng tsa matrix tsa aluminium tse fetotsoeng ka scandium li ile tsa fetoha sebaka se setle.Leha ho le joalo, ka lebaka la litšenyehelo tse phahameng tsa scandium, ho ntse ho etsoa lipatlisiso tse sebetsang bakeng sa modifier e theko e tlaase.Nikolai Kakhidze o ile a etsa tlhahiso ea ho nkela scandium sebaka ka daemane kapa aluminium oxide nanoparticles.Mosebetsi oa hae e tla ba ho hlahisa mokhoa oa ho kenya li-nanopowders ka mokhoa o nepahetseng oa ho qhibiliha ha tšepe.
Ha li kenngoa ka ho toba ka har'a ho qhibiliha, li-nanoparticles li kopantsoe ka li-agglomerate, tse nang le oxidized, 'me ha li na metsi,' me li etsa li-pores ho pota-pota.Ka lebaka leo, ho fumanoa litšila tse sa batleheng ho e-na le ho thatafatsa likaroloana.Ka laboratoring ea matla a phahameng le lisebelisoa tse khethehileng Univesithing ea Tomsk State, Sergey Vorozhtsov o se a ntse a ntlafalitse mekhoa ea saense le thekenoloji bakeng sa ho thatafala ha aluminium le magnesium ho tiisa hore ho kenngoa hantle ha li-nanoparticles tsa refractory ho qhibiliha le ho felisa mathata a ho koloba le ho phalla. .
- Ho itšetlehile ka tsoelo-pele ea basebetsi-'moho le 'na, morero oa ka o fana ka tharollo e latelang: li-nanopowders li fokotsehile (ka ho lekana ho ajoa) ka phofo ea aluminium ea boholo-holo ho sebelisa mekhoa e mengata ea thekenoloji.Ebe ligature e entsoe ho tsoa ho motsoako ona o lekaneng thekenoloji le o loketseng bakeng sa tšebeliso ea indasteri ka tekanyo ea indasteri.Ha ligature e kenngoa ka ho qhibiliha, masimo a ka ntle a sebetsanoa ho ajoa ka mokhoa o ts'oanang li-nanoparticles le ho eketsa metsi a mongobo.Kenyelletso e nepahetseng ea nanoparticles e ka ntlafatsa thepa ea 'mele le ea mochini oa alloy ea pele, - Nikolai Kakhidze o hlalosa moelelo oa mosebetsi oa hae.
Nikolai Kakhidze o rerile ho amohela lihlopha tsa pele tsa liteko tsa li-ligatures tse nang le nanoparticles bakeng sa kenyelletso ea tsona e latelang ho qhibiliha ho elella bofelong ba 2020. Ka 2021, ho reriloe ho fumana liteko tsa liteko le ho sireletsa litokelo tsa thepa ea mahlale.
