U-Nikolai Kakhidze, umfundi ophumelele kwi-Faculty ye-Physics kunye nobuNjineli, uye wacebisa ukusebenzisa i-diamond okanye i-aluminium oxide nanoparticles njengenye indlela ye-scandium ebiza kakhulu yokuqinisa i-alloys aluminium. Izinto ezintsha ziya kubiza amaxesha ama-4 ngaphantsi kwe-analog equkethe i-scandium eneempawu ezisondeleyo zomzimba kunye nezomatshini.
Okwangoku, iinkampani ezininzi zokwakha iinqanawa zizama ukutshintsha intsimbi enzima ngezinto ezilula kunye ne-ultra-light. Ukongeza ekunyuseni umthamo wokuthwala, oku kungasetyenziswa ngokufanelekileyo ukunciphisa ukusetyenziswa kwamafutha, ukunciphisa ukukhutshwa okunobungozi emoyeni kunye nokwandisa ukuhamba kwenqanawa kunye nokukhawulezisa ukuhanjiswa kwempahla. Amashishini kumashishini othutho kunye ne-aerospace nawo anomdla kwizinto ezintsha.
I-aluminiyam ye-matrix ye-composite imathiriyeli eguqulwe nge-scandium yaba yinto efanelekileyo endaweni. Nangona kunjalo, ngenxa yeendleko eziphezulu ze-scandium, ukukhangela okusebenzayo kuyaqhubeka kwi-modifier efikelelekayo. U-Nikolai Kakhidze ucebise ukutshintsha i-scandium ngedayimane okanye i-aluminium oxide nanoparticles. Umsebenzi wakhe uya kuba kukuphuhlisa indlela yokuqaliswa okuchanekileyo kwee-nanopowders kwi-melt melt.
Xa ifakwe ngokuthe ngqo kwi-melted, i-nanoparticles ihlanganiswe kwi-agglomerates, i-oxidized, kwaye ingabi namanzi, kwaye yenza iipores ezizijikelezileyo. Ngenxa yoko, ukungcola okungafunwayo kufumaneka endaweni yokuqina kwamaqhekeza. Kwilabhoratri yamandla aphezulu kunye nezinto ezikhethekileyo kwiYunivesithi yaseTomsk State, uSergey Vorozhtsov sele ephuhlise iindlela zesayensi kunye nezobuchwepheshe zokusabalalisa ukuqina kwe-aluminium kunye ne-magnesium eqinisekisa ukuqaliswa okuchanekileyo kwe-nanoparticles e-refractory ekunyibilikeni kunye nokuphelisa iingxaki zokumanzisa kunye ne-flotation. .
- Ngokusekelwe kuphuhliso lwabalingane bam, iprojekthi yam iphakamisa isisombululo esilandelayo: i-nanopowders i-de-agglomerated (ihanjiswe ngokulinganayo) kwi-powder aluminium ye-micro-ubungakanani usebenzisa imisebenzi emininzi yezobuchwepheshe. Emva koko i-ligature idityaniswe kulo mxube eyaneleyo yetekhnoloji kwaye ilungele ukusetyenziswa kwimizi-mveliso kwinqanaba loshishino. Xa i-ligature ifakwe kwi-melt, imimandla yangaphandle icutshungulwa ukuba isasaze ngokufanayo i-nanoparticles kwaye ikhulise ngakumbi ukumanzisa. Ukuqaliswa okuchanekileyo kwe-nanoparticles kunokuphucula iimpawu ezibonakalayo kunye nomatshini we-alloy yokuqala, - u-Nikolai Kakhidze uchaza ingundoqo yomsebenzi wakhe.
U-Nikolai Kakhidze uceba ukufumana iibhetshi zokuqala zokulinga ze-ligatures kunye ne-nanoparticles ngokungeniswa kwazo okulandelayo kwi-melt ekupheleni kwe-2020. Kwi-2021, kucetywayo ukufumana i-casting castings kunye nokukhusela amalungelo epropathi yengqondo.
