Ibisobanuro rusange kuri reaction Bonded SiC

JeneraliIbisobanuro byaIgisubizoYamazaki SiC

Igisubizo Bonded SiC ifite imiterere yubukanishi no kurwanya okiside. Igiciro cyacyo ni gito. Muri iki gihe, abantu benshi barushijeho kwitabwaho mu nganda zitandukanye.

SiC ni isano ikomeye cyane. Mu gucumura, igipimo cyo gukwirakwiza ni gito cyane. Mugihe kimwe, ubuso bwibice akenshi bitwikiriye urwego ruto rwa oxyde rufite uruhare runini rwo gukwirakwiza. SiC itunganijwe neza kandi yoroheje nta byongeweho. Nubwo inzira ishyushye ikoreshwa, igomba no guhitamo inyongeramusaruro ikwiye. Gusa ku bushyuhe bwo hejuru cyane, hashobora kuboneka ibikoresho bikwiranye nubucucike bwa tekinike hafi yubucucike bwa theoretical bigomba kuba biri hagati ya 1950 ℃ kugeza 2200 ℃ .Mu gihe kimwe, imiterere nubunini bizaba bike. Nubwo ibihangano bya SIC bishobora kuboneka kubituruka kumyuka, bigarukira mugutegura ubucucike buke cyangwa ibikoresho byoroshye. Kubera umwanya muremure utuje, ibiciro byumusaruro biziyongera.

Reaction Bonded SiC yahimbwe muri 1950 na Popper. Ihame shingiro ni:

Mubikorwa byingufu za capillary, silikoni yamazi cyangwa silikoni ivanze nigikorwa cyibikorwa byinjiye mubutaka bwiza burimo karubone kandi ikora silikoni ya karubone mubitekerezo. Carbide ya silicon nshya yashizwe hamwe ihujwe nuduce twambere twa silicon karbide ihagaze, kandi imyenge isigaye mu kuzuza yuzuyemo imiti yinjiza kugirango irangize inzira.

Ugereranije nubundi buryo bwa silicon carbide ceramics, inzira yo gucumura ifite ibintu bikurikira:

Ubushyuhe buke bwo gutunganya, igihe gito cyo gutunganya, ntakeneye ibikoresho bidasanzwe cyangwa bihenze;

Igisubizo Ibice bifatanye nta kugabanuka cyangwa guhindura ingano;

Uburyo butandukanye bwo kubumba (gukuramo, gutera inshinge, gukanda no gusuka)。

Hariho ubundi buryo bwo gushiraho. Mugihe cyo gucumura, ingano nini nibicuruzwa bigoye birashobora kubyara nta gitutu. Tekinoroji ya Reaction Bonded ya silicon karbide yizwe mugice cyikinyejana. Iri koranabuhanga ryabaye kimwe mu byibandwaho mu nganda zitandukanye kubera ibyiza byihariye.
