Kwinjira mu muyoboro w'imirasire ya Silicon Carbide: "Impuguke mu kurwanya ubushyuhe bwinshi" mu bushyuhe bw'inganda

Gushyushya ni intambwe y'ingenzi ariko ikomeye mu bintu byinshi bikorerwa mu nganda. Kuva ku gutunganya ubushyuhe bw'icyuma kugeza ku gushyushya ibikoresho bya ceramic, ndetse no gutunganya ibikoresho bimwe na bimwe byihariye, ibikoresho bishyushya bihamye, bikora neza kandi bishobora guhinduka birakenewe. Muri ibi bihe hakenewe ibisabwa cyane ku bushyuhe no kuramba,imirasire ya silicon carbideimiyoboro irimo kuba amahitamo y'ibigo byinshi bitewe n'inyungu zabyo zidasanzwe.
Hari abantu bashobora kuba bashishikajwe no kumenya niba umuyoboro w’imirasire ya silicon carbide ari iki? Mu magambo make, ni ikintu gishyushya cy’umuyoboro gikozwe ahanini mu byuma bya silicon carbide, ubusanzwe gikoreshwa hamwe n’insinga zishyushya, inkoni zishyushya n’izindi ngingo z’imbere, kandi kigira uruhare rw’ “umuyoboro w’ubushyuhe” mu itanura ry’inganda n’ibindi bikoresho. Ariko, umwihariko wacyo uri mu kuba kidatanga ubushyuhe bwinshi mu buryo butaziguye, ahubwo gitanga ubushyuhe ku gikoresho gikeneye gushyushywa mu buryo bw’imirasire binyuze mu bikoresho bishyushya imbere bizingiyeho, mu gihe kinarinda ibice by’imbere ikirere kigoye kiri mu itanura.
Ku bijyanye n'ibyiza by'imiyoboro ya silicon carbide, "ubushyuhe bwinshi" ni cyo kintu nyamukuru cyayo. Imiyoboro isanzwe ishyushya ibyuma ishobora kugira ubushyuhe bwinshi no gushonga ku bushyuhe bwa dogere selisiyusi magana menshi, mu gihe silicon carbide ceramics ubwayo ifite ubushyuhe bwinshi cyane. Ndetse no mu itanura rishyushye cyane riri hejuru ya 1300 ℃, ishobora kugumana ubuziranenge kandi ntiyoroshye kwangirika. Iyi miterere ituma ibasha guhangana n'ibintu byinshi bikorerwa mu bushyuhe bwinshi, nko gushyuha kw'imashini zimwe na zimwe zidasanzwe akenshi zirenga 1200 ℃, kandi imiyoboro ya silicon carbide radiation ishobora gukora neza muri bene ibyo bidukikije igihe kirekire.
Uretse kuba ifite ubushyuhe bwinshi, "ubudahangarwa na ruswa" nabwo ni ikintu gikomeye muri byo. Mu buryo bwinshi bwo gushyushya mu nganda, hashobora kuba hari imyuka ihumanya, aside cyangwa ibindi bintu byangiza mu itanura, bishobora kwangiza byoroshye ibintu bishyushya no kugabanya igihe cyo gukora ibikoresho. Ubudahangarwa bwa silicon carbide mu bikoresho bya shimi burakomeye, kandi ntabwo byoroshye kugirana n'ibi bintu byangiza, bivuze ko bishobora kugumana uburambe bwiza mu kirere cy'itanura rikomeye, kugabanya inshuro zo gusimbuza ibikoresho, kandi mu gihe kirekire, bikanagabanya ikiguzi cyo gukora no kubungabunga ibigo.
Byongeye kandi, "ubushobozi bw'ubushyuhe" bw'imiyoboro y'imirasire ya silicon carbide nabyo birakwiye kuvugwa. Uburyo bwayo bwo gutwara ubushyuhe ni bwiza, bushobora kwimura vuba ubushyuhe buterwa n'ibintu bishyushya imbere no gushyushya igikoresho hakoreshejwe imirasire. Ubu buryo bwo gushyushya ntibushyuha vuba gusa, ahubwo bunatuma ubushyuhe bukwirakwira mu itanura bungana, hirindwa ubushyuhe bwinshi cyangwa ubushyuhe budahagije. Ibi ni ingenzi cyane kugira ngo habeho ubwiza bw'ibicuruzwa. Urugero, mu gutunganya ubushyuhe bw'ibice by'icyuma, ubushyuhe bungana bugira ingaruka zitaziguye ku bukomere, gukomera, n'indi miterere y'ibice, kandi imiyoboro y'imirasire ya silicon carbide ishobora gutanga inkunga ihamye muri urwo rwego.

Birumvikana ko ikoreshwa ry'imiyoboro ya radiation ya silikoni carbide ridafite imbogamizi. Urugero, ikiguzi cyayo kiri hejuru ugereranyije n'icyiciro gisanzwe cy'imiyoboro ishyushya ibyuma, kandi bitewe n'imiterere y'ibikoresho bya ceramic, bigomba kwirinda impanuka zikomeye mu gihe cyo kuyishyiraho no kuyikoresha kugira ngo birinde kwangirika. Ariko ku nganda zifite ibisabwa byinshi mu bushyuhe, kwangirika kw'ibidukikije, n'ubwiza bw'ibicuruzwa, gutuza, gukora neza, no kuramba kwayo akenshi bigabanya izi mbogamizi nto.
Muri iki gihe, bitewe n’iterambere ry’inganda mu iterambere rijyanye no kunoza no ku rwego rwo hejuru, ibisabwa ku bikoresho bishyushya nabyo biriyongera buri gihe. Nk’ikintu cyiza cyane gishyushya mu nganda, imiyoboro ya silicon carbide irimo kugira uruhare runini buhoro buhoro mu nzego nka ceramic, metallurgie, na electronics. Bishobora kuba bitaryoshye cyane nk’ikoranabuhanga rimwe na rimwe rigezweho, ariko ni uku kuba "ufata umwanya waryo" bucece mu bidukikije bikomeye bituma iba "inzobere ikomeye mu guhangana n’ubushyuhe bwinshi" mu nganda, itanga garanti yizewe ku buryo butandukanye bwo gushyushya bukenewe cyane.
