Kuva mu miyoboro itwara abantu kugera ku binyabiziga bishya by’ingufu, kuva ku ziko ry’ubushyuhe bwo hejuru kugeza kuri satelite yo mu kirere, ibikoresho bizwi nka “diyama y’inganda” byandika bucece imbibi z’inganda zigezweho.Silicon carbide ceramics, ibikoresho bya superhard bifite ubukana bwa kabiri nyuma ya diyama karemano, bitera impinduramatwara ituje mubice bitandukanye nkinganda zigezweho, semiconductor, icyogajuru, nimbaraga nshya bitewe nubushyuhe bwayo bukabije, imishwarara ikomeye, hamwe nubushyuhe bwiza bwumuriro.
Iyo 'amagufwa akomeye' ahuye no gukora neza
Niba ubukerarugendo gakondo ari ubururu n'umweru byera mubukorikori n'ubukorikori, noneho silicon karbide ceramics isa nisaha yo mubusuwisi mubikoresho byuzuye. Ubukomezi bwayo bukubye inshuro 3-5 zubukorikori busanzwe, kandi ubu bukomere hafi ya diyama karemano butuma inzira yo gutunganya nko kubaza ku byuma - ibikoresho bisanzwe byo gutema bishaje ku muvuduko utangaje mugihe cyo gutema. Ikirushijeho gukomera ni uko imiterere "ikomeye" ya karubide ya silicon ituma ikunda guturika ndetse ikosa rito mugihe cyo kuyitunganya, cyane cyane kubice bimwe na bimwe bikikijwe n'inkuta zisaba ubwitonzi nkibikorwa bya kristu.
Ariko icyifuzo cyinganda zigezweho niterambere ryiterambere. Ba injeniyeri basanze urufunguzo rwo gukemura iki kibazo ruri mu guhuza gukomera no guhinduka: kugumana imiterere yimbere yibikoresho mugihe ushyira mugenzuzi neza mugihe cyo gutunganya. Nkuko abatetsi bo hejuru bamenya ubushyuhe, tekinoroji igezweho yo gutunganya ibintu bigenda byinangira buhoro buhoro binyuze mukugenzura neza ubushyuhe, umuvuduko, ninshuro zinyeganyega.
Imfunguzo eshatu zo gufungura diyama yinganda
1. Gushushanya gukanda
Ubu ni bumwe mu buryo busanzwe bwo gutunganya silicon karbide ceramics. Ubu buryo bushyira ifu ya karubide ya silicon cyangwa ifu ivanze muburyo bushyushye kandi ikabitunganya muburyo bwubushyuhe bwinshi nigitutu. Ifite umusaruro mwinshi kandi ikora neza, kandi irakwiriye kubyara umusaruro munini wa silicon karbide ceramic ceramic nkibikoresho byo gutema, plaque ya aluminiyumu ishushe, nibindi.
2. Gushushanya
Ubu ni uburyo buke kandi bwihuse bwo gukora ibicuruzwa bya ceramic silicon. Ubu buryo buvanga ifu ya silicon karbide nizindi nyongeramusaruro, ikabongerera mumazi kugirango ikorwe, hanyuma ikayitera mubibumbano. Noneho, biratunganywa kandi bigakorwa binyuze mukumisha no hejuru yubushyuhe bwo hejuru, hamwe nigihe gito cyo gutunganya nigiciro gito. Birakwiriye gutegura imbaraga-nyinshi, ibice byinshi-byuzuye hamwe nibintu bitwara imitwaro.
3. Ifu ya metallurgie
Ifu ya metallurgie nuburyo bwo kuvanga no gushiraho ifu ya karubide ya silicon mukigero runaka, hanyuma ukayicumura mubushyuhe bwinshi numuvuduko mwinshi. Ubu buryo bufite uburyo bworoshye bwo kubyaza umusaruro, imiterere yibicuruzwa bitandukanye, hamwe nuburyo bunoze bwo gutunganya, bigatuma bukorwa neza cyane, butera imbaraga nyinshi, hamwe n’ibicuruzwa by’ubutaka bwangiza.
Kuva muri laboratoire kugeza ku musaruro mwinshi ku murongo w’ibicuruzwa, intambwe imaze guterwa mu gutunganya ubukorikori bwa silicon karbide ceramics yemeza ukuri: nta bikoresho bidashobora gutunganywa, gusa ikoranabuhanga ritaracika. Hamwe no gukura kwikoranabuhanga rishya nko gutunganya lazeri no gucumura microwave, ibi bikoresho bimaze kuba ibintu bitangaje bigenda byiyongera mu nganda zifite ubwenge, bitera imbaraga zikomeye mu "gukora ubwenge bw’abashinwa".
Mu nyanja nini yubushakashatsi bwikirere hamwe nicyatsi kibisi cyingufu zisukuye, ceramika ya silicon karbide yandika imigani yinganda ziki gihe hamwe nibintu byihariye bidasanzwe. Uku kwerekana hagati yubukomezi nubwenge birashobora kuba ikimenyetso cyiteka cyubumuntu kirenga imipaka yikoranabuhanga.
