Ibumba rya silicon carbide (SiC)zizwiho imbaraga zazo zidasanzwe, kwihanganira ubushyuhe, no kuramba kwazo. Izi ngaruka zituma ziba nziza cyane mu bidukikije bikomeye, nka moteri z'indege cyangwa imashini z'inganda. Ariko se ibi bikoresho bigezweho bikorwa bite? Reka dusesengure intambwe ku yindi.
1. Gutegura ibikoresho fatizo
Byose bitangirira ku ifu ya silikoni karubide nziza cyane. Tekereza ibi nk'"ifu" yo guteka "keke" ya ceramic. Kugira ngo wongere imiterere y'ibikoresho bya nyuma, ibintu bike byongewemo—nk'iy'aluminium oxyde cyangwa boron compounds—biravangwa. Ibi byongewemo bikora nk'uko kole ikora mu bihe bya nyuma, bigafasha utunyangingo gufatana neza.
2. Gushushanya Ceramic
Hanyuma ifu ihinduka uburyo bwo kuyibumba. Uburyo bubiri busanzwe bukoreshwa:
Gukanda: Ifu ishyirwa mu ishusho runaka hakoreshejwe umuvuduko mwinshi, nk'uko urubura rukomeza gukanda rugakora umupira w'urubura.
Gutera Inshinge: Ifu ivangwa n'agakoresho k'agateganyo (nk'ishashara) kugira ngo hakorwe uruvange rumeze nk'ifu, rushyirwa mu bimera kugira ngo habeho imiterere igoye.
Muri iki cyiciro, ibikoresho biracyari byoroshye—nk'igishushanyo cyumye cy'umucanga—kandi bigomba “gutekwa” kugira ngo bikomere.
3. Uburyo bwo gukaraba
Aha niho habera ubumaji. Ibumba rifite ishusho rishyushya mu itanura ryabugenewe ku bushyuhe bwinshi cyane (akenshi rirenga 1.800°C). Mu gihe cyo gutwika, ibintu bibiri by'ingenzi bibaho:
Uduce dufatanye: Uduce twa silikoni karubide turakura twegerana, dukuramo icyuho kandi tugakora imiterere ikomeye.
Inyongeramusaruro zirakora: Ibinyabutabire byongewemo bishonga gato, bigatuma habaho "ikiraro" hagati y'ibinyabutabire kugira ngo byongere ubukomere.
Ibidukikije biri mu itanura bigenzurwa neza—rimwe na rimwe byuzuyemo imyuka idakora—kugira ngo hirindwe ingaruka zitari ngombwa.
4. Imyitozo yo kurangiza
Nyuma yo gushwanyagurika, ibumba rishobora kunyuzwamo ubundi buryo bwo kunoza imikorere yaryo:
Gusukura: Ku bijyanye no gukoresha ibintu bisaba ubuso bworoshye (urugero: imitako cyangwa ibyuma bifunga).
Gupfuka: Uduce duto two kurinda (nk'udusimba twa silicon nitride) dushobora kongerwamo kugira ngo twongere ubushobozi bwo kwangirika.
Gutunganya imashini: Gukata cyangwa gucukura neza kugira ngo ugere ku bipimo bya nyuma.
Impamvu iyi gahunda ari ingenzi
Ibanga ry'imbaraga za karuboni ya silikoni riri mu buryo atome zayo zifatanya mu gihe cyo gushyuha. Uburyo bushyuha cyane butuma habaho urusobe rw'imigozi ikomeye ya silikoni na karuboni, irwanya ubushyuhe, ingese, n'imihangayiko ifatika. Inyongeramusaruro n'igenzura ryimbitse ry'ubushyuhe bituma umusaruro wa nyuma udakomera gusa ahubwo unakomera bihagije kugira ngo udacika.
Ishusho Nkuru
Kuva kuri turbine zigezweho kugeza kuri sisitemu zo kugenzura ihumana ry’imyanda, silicon carbide ceramics igira uruhare runini mu ikoranabuhanga rya none. Nubwo inzira yo gukora ari igoye, ni uku kuringaniza neza siyansi n’ubuhanga bihindura ifu yoroshye mo ibikoresho bishobora kwihanganira imimerere mibi cyane.
Uko ubushakashatsi bugenda butera imbere, uburyo bushya—nk'icapiro rya 3D ry'ibibumbano—buragenda buvuka, butanga icyizere cy'uko ibi bikoresho bidasanzwe bizakoreshwa mu buryo bushya kurushaho.
