Nikolai Kakhidze, nwa akwụkwọ gụsịrị akwụkwọ na ngalaba nke Physics na Engineering, atụwo aro iji diamond ma ọ bụ aluminom oxide nanoparticles dị ka ihe ọzọ na scandium dị oke ọnụ maka ime ka aluminom alloys sie ike. Ihe ọhụrụ a ga-eri ugboro anọ erughị analog nke nwere scandium nwere ezigbo anụ ahụ na arụ ọrụ.
Ugbu a, ọtụtụ ụlọ ọrụ na-arụ ọrụ ụgbọ mmiri na-agbalịsi ike iji ihe ọkụ na ọkụ dị ọkụ dochie ígwè dị arọ. Na mgbakwunye na ịba ụba ikike ibu, nke a nwere ike itinye n'ọrụ nke ọma iji belata oriri mmanụ, na-ebelata ihe ọkụkụ na-emerụ ahụ n'ime ikuku na ịba ụba nke ụgbọ mmiri na ngwa ngwa nnyefe nke ibu. Ụlọ ọrụ dị na ụgbọ njem na ụlọ ọrụ ikuku na-enwekwa mmasị na ihe ọhụrụ.
Ihe mejupụtara matriks aluminom ejiri scandium gbanwetụrụ ghọrọ ezigbo nnọchi. Otú ọ dị, n'ihi ọnụ ahịa dị elu nke scandium, a na-eme nchọpụta na-arụsi ọrụ ike maka mgbanwe mgbanwe dị ọnụ ala karị. Nikolai Kakhidze tụrụ aro iji diamond ma ọ bụ aluminom oxide nanoparticle dochie scandium. Ọrụ ya ga-abụ ịmepụta usoro maka ntinye ziri ezi nke nanopowders n'ime agbaze ígwè.
Mgbe etinyere ya ozugbo na agbaze, a na-ejikọta nanoparticles n'ime agglomerates, oxidized, na ọ bụghị wetted, ha na-etolite pores gburugburu onwe ha. N'ihi ya, a na-enweta adịghị ọcha na-achọghị ka ọ bụrụ ihe na-esi ike. Na laabu nke elu-ike na ihe pụrụ iche na Tomsk State University, Sergey Vorozhtsov emebeworị nkà mmụta sayensị na nkà na ụzụ obibia maka agbasasị hardening nke aluminom na magnesium na-ahụ na ezi iwebata refractory nanoparticles n'ime gbazee na-ewepụ nsogbu nke wettability na flotation. .
- Dabere na mmepe nke ndị ọrụ ibe m, ọrụ m na-atụ aro ihe ngwọta na-esonụ: nanopowders na-de-agglomerated (kesaa na-ekesa) na obere ntụ ntụ aluminum na-eji ọtụtụ ọrụ nkà na ụzụ eme ihe. Mgbe ahụ, a na-emepụta ligature site na ngwakọta a nke zuru oke na nkà na ụzụ ma dị mma maka iji ụlọ ọrụ eme ihe n'ọtụtụ ụlọ ọrụ. Mgbe ligature na-ewebata n'ime gbazee, mpụga ubi na-esichara ka uniformly kesaa nanoparticles na n'ihu dịkwuo wettability. Okwu mmeghe ziri ezi nke nanoparticles nwere ike imeziwanye ihe anụ ahụ na akụrụngwa nke alloy mbụ, - Nikolai Kakhidze na-akọwa isi ọrụ ya.
Nikolai Kakhidze na-ezube ịnata batches nnwale mbụ nke ligatures na nanoparticles maka mmeghe ha na-esote n'ime agbaze na njedebe nke 2020. Na 2021, a na-eme atụmatụ inweta ihe nkedo ikpe ma chebe ikike ikike ọgụgụ isi.
Ụdị nchekwa data kacha ọhụrụ na-esetịpụ ụkpụrụ ọhụrụ maka nyocha enwere ike imepụtagharị, na-enye ụzọ a pụrụ ịdabere na ya maka…
