Iterambere rishya muburyo bwo kurwanya assing ibikoresho byikirahure

Vuba aha, Ikigo cy'ubukanishi bw'ishuri ry'ubumenyi bw'Ubushinwa ryakoranye n'abashakashatsi bo mu rugo ndetse no mu mahanga kugira ngo rubaze ibihumyo bikabije by'ikirahure gisanzwe mu gipimo cya ultra-yihuse. Ibisubizo bifitanye isano nitwa Ultray Rejuvention Ibirahuri bya Metallic Block Brack Kwiyongera, byasohotse mu iterambere rya siyansi (iteza imbere siyanse 5: EAAW6249 (2019)).

Ibikoresho byikirahure bifite impengamiro yo gusaza itangwa na termOdynamic equilibriclium iringaniye, kandi icyarimwe, iraherekezwa no kwangirika kumitungo. Ariko, ukoresheje ingufu zo hanze, ibikoresho byikirahure birashobora kuvugurura imiterere (rejuvetation). Iyi nzira yo kurwanya ihohoterwa ku kuboko kumwe igira uruhare mu gusobanukirwa shingiro kumyitwarire igoye yikirahure, kurundi ruhande nabyo bifasha kandi gushyira mubikorwa byubuhanga bwibikoresho byikirahure. Mu myaka yashize, kubikoresho byikirahure byikirahure hamwe nuburyo bwagutse, urukurikirane rwuburyo bwo kuvugurura imiterere ishingiye kubijyanye no kwimenyekanisha bidateganijwe hateganijwe kugenzura neza imitungo. Ariko, uburyo bwose bwo kuvugurura bukora kurwego rwo hasi kandi bisaba igihe kirekire cyane, bityo akaba ufite imbogamizi zikomeye.

Abashakashatsi bashingiye ku masahani y'isahani ebyiri z'ibimenyetso bigira ingaruka ku gikoresho cy'imbunda cyoroheje, bamenye ko ikirahuri gishingiye kuri zirconium gisanzwe cyahujwe n'urwego rwo hejuru muri 365 na miriyoni isaba umuntu guhumbya ijisho). Enthalpy idasuzumwa cyane. Ikibazo cy'ikoranabuhanga ni ugukoresha byinshi muri GPA-Urwego rukora-impimbavu-mu buryo bwihuse ku kirahure cy'icyuma, kugira ngo wirinde kunanirwa kw'ibikoresho nk'ibisimba no gutekerezwa. Muri icyo gihe, mugenzura umuvuduko w'ingaruka wa flayeri, icyuma gisubirwamo byihuse ikirahure "gikonje" mu nzego zitandukanye.

Abashakashatsi bakoze ubushakashatsi bunoze ku nzira yo kuvugurura ultra-yihuta yikirahure cyicyuma giturutse kubitekerezo bya termodenamike, imiterere myinshi hamwe na phonon. Ubudozi bwubusa byatewe na "imiyoboro yo mu nzibacyuho". Dufatiye kuri ubu buryo bwumubiri, nimero ya Deborantless idafite igipimo irasobanuwe, isobanura ibishoboka kumwanya wa ultra-wihuse wihuta yikirahure. Uyu murimo wongereye igihe cyo kuvugurura imirongo yikirahure cyibirahure byibuze 10 yubunini, yaguye imirima ya porogaramu, kandi irushaho gusobanukirwa nabantu bafite imbaraga zikirahure.
