Mubice bigezweho nka semiconductor, ingufu nshya, hamwe nikirere, ibikoresho bya ceramic yumukara-umukara biraceceka bigira uruhare runini. Nisilicon carbide ceramic- ibikoresho bifite ubukana bugereranywa nubwa diyama, ihindura isura yinganda zigezweho neza cyane kubera ubushyuhe bwayo bwinshi, kurwanya ruswa hamwe nubushyuhe bwinshi. Ariko bike bizwi ni uko guhindura ifu ya karubide ikomeye ya silicon mubikoresho byuzuye, birasabwa inzira yubumaji "yubushyuhe bwo hejuru".
I. Uburyo bwo gucumura: Ubumaji bw'ingenzi bwo guhindura amabuye zahabu
Niba ifu ya silicon karbide igereranijwe na jade idafite ibara, inzira yo gucumura nuburyo bwibanze bwo kubigira ibicuruzwa byiza. Binyuze mu bushyuhe bwo hejuru cyane kuri 800-2000 ℃, uduce duto twa micron nini ya poro yongeye- "guhana ibiganza" kurwego rwa atome, bigakora umubiri wuzuye kandi ukomeye. Uburyo butandukanye bwo gucumura, nkubuhanga butandukanye bwo gushushanya, guha ibikoresho bifite imikorere idasanzwe:
1. Umuvuduko ukabije wa Atmospheric: Gukunda cyane "guteka buhoro hejuru yubushyuhe buke"
Nkuko isupu itetse buhoro isupu iryoshye igomba gukongezwa hejuru yubushyuhe buke, ubu buryo butuma ifu isanzwe yiyongera binyuze mubushyuhe burebure. Nubwo uruziga ari rurerure, rushobora kugumana "uburyohe bwumwimerere" bwibikoresho kandi birakwiriye cyane kubikoresho bya semiconductor hamwe nibisabwa byera.
2. Icyaha gishyushye cyane: Igenzurwa neza "tekinike yo guhimba cyane"
Gukoresha ingufu za mashini mubushyuhe bwo hejuru ni nko gutanga "massage hot compressage" neza kubintu, bishobora gukuraho vuba icyuho cyimbere. Ibice bya ceramic byakozwe niki gikorwa bifite ubucucike hafi yagaciro kerekana kandi ni amahitamo meza yo gukora ibicuruzwa neza na kashe.
3. Guhindura reaction: "Ubumaji bwa Shimi" mubikoresho byisi
Mugukoresha ubuhanga ukoresheje imiti hagati ya silicon na karubone, icyuho gihita cyuzura mugihe cyo gucumura. Iyi mikorere "yo kwikiza" ituma iba igikoresho gikomeye cyo gukora ibice bigoye kandi bidasanzwe, bikwiranye nubushyuhe butandukanye bwo guhangana nubushyuhe bwo hejuru, birinda kwambara, birwanya ruswa cyangwa ibindi bice byabigenewe.
Ii. Guhitamo Inzira: Ubwenge bwo kudoda kugirango bikwiranye
Nkuko abadozi bakuru bahitamo ubudozi bushingiye kubiranga umwenda, injeniyeri bakeneye gusuzuma byimazeyo ibisabwa kubicuruzwa:
Iyo uhanganye nibice bitameze nk'uruzitiro rudasanzwe, "tekinoroji yo kwinjira" yo gucumura irashobora kugumana imiterere myiza
Imiyoboro ya Semiconductor ifite ibyangombwa bisabwa hejuru ya ultra-flat irashobora gutuma habaho ihinduka rya zeru binyuze mumashanyarazi asanzwe
Iyo uhuye nibintu byinshi biremereye, ultra-high density of hot-pressing sintering akenshi ihitamo
Iii. Intambwe itagaragara ya tekinoroji
Mu mateka y'ubwihindurize ya tekinoroji yo gucumura, udushya tubiri twihishe ni ingenzi cyane: kwiyongera byibuze byibasiwe na sida yo gucumura ni nka "kole ya molekile", igabanya gukoresha ingufu mugihe byongera imbaraga; Sisitemu yo kugenzura ubushyuhe bwa digitale igereranywa n "umutetsi wubwenge", ukomeza guhindagurika kwubushyuhe muri ± 5 ℃ no kwemeza imikorere ya buri cyiciro cyibikoresho.
Kuva mu nganda zidashobora kwangirika no kwangirika kwangirika kugeza mu nganda zateye imbere za semiconductor, ceramics ya silicon carbide ceramics irimo guhindura imiterere yinganda zigezweho. Guhora udushya twubuhanga bwo gucumura ni nko guha amababa ibi bikoresho byubumaji, bikabasha kuguruka mukirere cyagutse. Nkumushinga wumwuga ukora cyane mubijyanye nubutaka bwa silicon carbide ceramics mumyaka irenga icumi, Shandong Zhongpeng yumva neza ibiganiro hagati yibikoresho no kugenzura ubushyuhe kurusha abandi. Buri gutunganya neza umurongo wo gucumura ni ukongera kwiyubaka kwa "ubushyuhe-bwumuvuduko-wigihe" inyabutatu ya zahabu. Kuzimya itanura n'umuriro w'itanura bikomeje kwandika igice cyubwihindurize cyubutaka bwinganda. Twishingikirije ku cyizere cy’ubushakashatsi n’iterambere byigenga hamwe n’ikoranabuhanga ryemewe ryemewe, buri gihe twiyemeje guha abakiriya igisubizo kimwe kiva mu kweza ibikoresho fatizo kugeza kucumura neza, tukareba ko ibicuruzwa byose bya ceramic carbide ceramic bitwara ubushyuhe bwimyaka icumi yubukorikori. Inzira iri imbere iragabanijwe, kandi binyuze muburyo bwo guhimba, iba shyashya. Turagutumiye tubikuye ku mutima ngo twifatanye natwe guhamya uburyo iki kibatsi cyubwenge mubukorikori bwinganda kimurika byinshi bidashoboka. Buri gihe twizera ko iterambere ryose mubikoresho siyanse irimo gukusanya imbaraga kugirango ikiremwamuntu kirenze imipaka yikoranabuhanga.
