Ibumba rya karubide rya silikonini ibikoresho by'ingenzi mu nganda zitandukanye bitewe n'imiterere yabyo yihariye, harimo ubukana bwinshi, ubucucike buke no kudashyuha neza. Iyi miterere ituma silicon carbide (SiC) iba amahitamo meza yo gukoreshwa mu buhanga bwa mekanike, inganda zikora imiti n'ibyuma, amatanura n'ibikoresho bitandukanye bishyushya. Iyi nkuru irasuzuma mu buryo bwimbitse ikoreshwa ry'ibibumbano bya silicon carbide, igaragaza akamaro kabyo mu nganda zigezweho n'inganda.
Mu rwego rw'ubuhanga mu by'ubukanishi, ibumba rya silikoni karubide rikoreshwa cyane bitewe n'ubukana bwaryo bwiza no kudashira. Ibi bikoresho birakwiriye cyane mu gukora ibice bito bikingira ubushyuhe n'ibice byangiritse bisaba kuramba no kwizerwa. Ibumba rya silikoni rishobora kwihanganira ubushyuhe bwinshi ritahinduye cyangwa ngo ritakaze imiterere yaryo, bigatuma riba ryiza cyane mu imashini zikora neza. Uko inganda zikomeje gusaba ibice bikora neza kandi biramba, uruhare rwa silikoni karubide mu bukanishi byitezwe ko ruzakura cyane.
Inganda zikora imiti n'ibyuma nazo zungukiye cyane ku bibumbano bya silikoni karubide. Ibi bikoresho bifite ubushobozi bwo kurwanya ingese, cyane cyane ibyuma bishongeshejwe, ibisigazwa n'ibyuma bya alkali. Iyi miterere ni ingenzi cyane mu bidukikije aho ibikoresho gakondo bizangirika, bigatuma igihe cyo kubikora gihenda no kubyitaho. Ikigaragara ni uko abarenga 65% by'amatanura manini ku isi bakoresha ibikoresho bya silikoni karubide ya silikoni nk'ibikoresho by'umubiri w'amatanura. Iyi mikoreshereze ntiyongerera gusa igihe cyo gukora amatanura ku kigero cya 20-40%, ahubwo inanoza imikorere. Byongeye kandi, ibibumbano bya silikoni karubide bikoreshwa nk'ibikoresho byo gushongesha ibyuma nka aluminiyumu, umuringa na zinc, bigaragaza ko bifite ubushobozi bwo gukora ibintu byinshi mu bushyuhe bwinshi.
Mu matanura yo mu nganda, ibumba rya silicon carbide rigira uruhare runini mu kunoza imikorere n'imikorere myiza y'ingufu. Gukoresha ibikoresho byo mu ibumba rya silicon carbide bishobora kugabanya cyane uburemere n'ibikenewe mu mwanya, ibyo bikaba ingirakamaro cyane ku nganda nk'inganda zoroheje, ibikoresho by'ubwubatsi n'ibikoresho by'ikoranabuhanga. Uburemere bworoheje bw'ibice bya silicon carbide bufasha kunoza ikoreshwa ry'ingufu kuko hakenerwa ingufu nke kugira ngo ishyushye itanura. Byongeye kandi, ubushobozi bwiza bwo kurwanya ingaruka z'ibikoresho bya silicon carbide butuma ubushyuhe bwo kurasa bwiyongera vuba, birushaho kunoza imikorere y'itanura.
Ibumba rya silicon carbide naryo ni ingenzi mu bikoresho bitandukanye bishyushya bikoreshwa mu gushyushya, gushonga no gutunganya ubushyuhe. Gushyushya mu buryo butaziguye hakoreshejwe gaze byabaye uburyo bwiza muri ibi bikorwa kuko bituma ubushyuhe burushaho kunozwa neza mu gihe bigabanya imyuka mibi, nka azote oxyde (NOx). Gukoresha silicon carbide muri ibi bikoresho bishyushya ntibituma imikorere irushaho kuba myiza gusa ahubwo binahuza n'imbaraga mpuzamahanga zo kugabanya ingaruka ku bidukikije. Mu gihe inganda ziharanira ibisubizo birambye ku bidukikije, icyifuzo cya silicon carbide ceramics cyo gukoresha mu gushyushya gishobora kwiyongera.
Uburyo bwo gukora ibintu bitandukanye bya silikoni karubide burenze uburyo busanzwe bwo gukoreshwa kuko bugenda bukoreshwa mu ikoranabuhanga rigezweho. Urugero, mu rwego rw'ibikoresho by'ikoranabuhanga, silikoni karubide ikoreshwa mu gukora semiconductors n'ibikoresho by'amashanyarazi. Uburyo bushyuha cyane n'ubushobozi bwo gukingira amashanyarazi bya silikoni karubide bituma iba nziza mu bikorwa by'ikoranabuhanga bikoresha frequency nyinshi n'ubushyuhe bwinshi. Uko icyifuzo cy'ibikoresho by'ikoranabuhanga bikomeza kwiyongera kandi byizewe, silikoni karubide karubide byitezweho kugira uruhare runini mu gukora ibikoresho by'ikoranabuhanga mu gihe kizaza.
Byongeye kandi, inganda zikora mu kirere n'imodoka zitangiye kubona ubushobozi bwa silicon carbide ceramics ku bikoresho byoroshye kandi bikomeye. Ubushobozi bwa silicon carbide bwo kwihanganira ubushyuhe bukabije n'ibidukikije bibi butuma iba amahitamo meza yo gukoreshwa nko mu nsinga za turbine, disiki za feri, n'ibindi bice by'ingenzi. Mu gihe izi nganda zishaka kunoza imikorere myiza ya lisansi no kugabanya imyuka ihumanya ikirere, gushyira silicon carbide ceramics mu miterere yazo bishobora kunoza cyane imikorere no kuramba.
Muri make, ikoreshwa rya silicon carbide ceramics riri mu buryo butandukanye, bitewe n'imiterere yaryo yihariye n'ibyiza byaryo mu mikorere. Kuva ku buhanga bwa mekanike kugeza ku gutunganya imiti, amatanura n'ibikoresho by'ikoranabuhanga bigezweho, silicon carbide ceramics byagaragaye ko ari igice cy'ingenzi mu nganda zigezweho. Uko ikoranabuhanga rikomeza gutera imbere, ubushobozi bwa silicon carbide ceramics bwo gutanga ibisubizo bishya no gukora ibikorwa birambye buziyongera gusa. Ahazaza h'silicon carbide ceramics buratanga icyizere, kandi ubushakashatsi n'iterambere bikomeje birimo gutegura inzira y'ikoreshwa rishya no kunoza imikorere mu nzego zitandukanye.
