Nikolai Kakhidze, umunyeshuri wahawe impamyabumenyi mu ishami rya fiziki n’ubuhanga, yatanze igitekerezo cyo gukoresha diyama cyangwa aluminium oxyde nanoparticles mu rwego rwo gusimbuza scandium ihenze yo gukomera aluminiyumu. Ibikoresho bishya bizatwara inshuro 4 munsi ugereranije na scandium irimo igereranya hamwe nibintu bya hafi byumubiri nubukanishi.
Kugeza ubu, amasosiyete menshi yubaka ubwato araharanira gusimbuza ibyuma biremereye nibikoresho byoroheje kandi byoroheje. Usibye kongera ubushobozi bwo gutwara, ibi birashobora gukoreshwa muburyo bwo kugabanya ikoreshwa rya lisansi, kugabanya ibyuka bihumanya ikirere no kongera umuvuduko wubwato no kwihutisha itangwa ryimizigo. Ibigo mu nganda zitwara abantu n’ikirere nabyo bishishikajwe nibikoresho bishya.
Aluminium matrix yibikoresho byahinduwe hamwe na scandium byabaye umusimbura mwiza. Ariko, kubera igiciro kinini cya scandium, ubushakashatsi burakomeje burimo guhinduka cyane. Nikolai Kakhidze yatanze igitekerezo cyo gusimbuza scandium na diyama cyangwa aluminium oxyde nanoparticles. Inshingano ye izaba iyo gutegura uburyo bwo kwinjiza neza nanopowders mu cyuma gishonga.
Iyo byinjijwe mu buryo butaziguye mu gushonga, nanoparticles ikusanyirizwa hamwe muri agglomerate, okiside, kandi ntisukuye, kandi ikora imyenge ikikije. Nkigisubizo, umwanda udashaka uraboneka aho gukomera ibice. Muri laboratoire y’ingufu nyinshi n’ibikoresho bidasanzwe muri kaminuza ya Leta ya Tomsk, Sergey Vorozhtsov yamaze gushyiraho uburyo bwa siyansi n’ikoranabuhanga bwo gukwirakwiza gukomera kwa aluminium na magnesium bituma habaho kwinjiza neza nanoparticles zishonga mu gushonga no gukuraho ibibazo by’ubushuhe no guhindagurika. .
- Nkurikije iterambere rya bagenzi banjye, umushinga wanjye urasaba igisubizo gikurikira: nanopowders de-agglomerated (ikwirakwizwa) mu ifu ya aluminium nini ya mikoro ikoresheje ibikorwa byinshi byikoranabuhanga. Noneho ligature ikomatanyirizwa muri iyi mvange ifite tekinoroji ihagije kandi yoroshye yo gukoresha inganda murwego rwinganda. Iyo ligature yinjijwe mumashanyarazi, imirima yo hanze itunganywa kugirango igabanye kimwe nanoparticles kandi irusheho kongera ubushuhe. Gutangiza neza nanoparticles birashobora kunoza imiterere yumubiri nubukanishi bwambere, - Nikolai Kakhidze asobanura ishingiro ryumurimo we.
Nikolai Kakhidze arateganya kwakira icyiciro cya mbere cy’igeragezwa cya ligature hamwe na nanoparticles kugira ngo binjire mu mashanyarazi mu mpera za 2020. Mu 2021, biteganijwe ko hazaburanishwa iburanisha no kurengera uburenganzira ku mutungo bwite mu by'ubwenge.
