Umuyoboro wo kurinda RSiC
Amakuru ku bicuruzwa
Imiyoboro yo kurinda karubide ya silikonini ibice byihariye by’imiyoboro bikozwe mu bikoresho bya silicon carbide (SiC) bya ceramic, bikoreshwa cyane cyane mu kurinda ibintu bishobora kwangirika (nk'ibinyabutabire) cyangwa nk'ibice by'ingenzi mu bikoresho byo gutwara amazi n'ubushyuhe bwinshi.
Ibicuruzwa byacu ahanini bikorwa hakoreshejwe uburyo butatu:Guhindura imiterere y'ibice (RBSiC), Guhindura imisemburo (RSiC), Karubide ya silikoni ifatanye na nitride (NSiC)
1. Imiyoboro yo kurinda RSiC
Hakoreshejwe ifu nto ya SiC ifite pure nyinshi nk'ibikoresho fatizo, iracukurwa ku bushyuhe bwinshi (2000–2200℃). Inyubako ikomeye ikorwa binyuze mu gusubiramo no guhuza ibinyampeke bya SiC ubwabyo, nta kindi cyiciro cyo guhuza.
Ibiranga by'ingenzi:
Ubudahangarwa budasanzwe ku bushyuhe bwinshi:Ubushyuhe bw'igihe kirekire bugera kuri 1600℃, bugakomeza guhangana n'ubushyuhe bw'igihe gito kuri 1800℃, bigatuma iba nziza cyane mu bijyanye no guhangana n'ubushyuhe bwinshi muri ubwo bwoko butatu, ikwiriye amatanura ashyushye cyane (nk'amatanura ya keramike n'amatanura ya metallurgike).
Ubudahangarwa bwiza bwo kurwanya okiside:Mu bushyuhe bwinshi, firime nini yo kurinda SiO₂ irakora ku buso, ikabuza SiC y'imbere gukomeza gushonga, ikagaragaza ubusugire bukabije mu kirere gishyushya.
Korejimetero nke cyane yo kwagura ubushyuhe:Igipimo cyo kwaguka k'ubushyuhe ni 4.5 × 10⁻⁶ /℃ gusa, bitanga ubudahangarwa bwiza bw'ubushyuhe, nubwo ari munsi gato y'ubwa karubide ya silikoni ifatanye na nitride.
Ubukomere bwinshi n'ubudahangarwa bwinshi:Kubera ko ifite ubukana bwa Mohs hafi ya 9, igaragaza ubudahangarwa bukomeye ku isuri n'ubusa bw'ibintu, bigatuma ikwiriye guhumeka neza mu bushyuhe bwinshi no mu mazi arimo uduce duto.
Ubudahangarwa bukomeye bw'ibinyabutabire:Irwanya aside ikomeye na alkali, kandi ntigira ingaruka ku byuma byinshi byashongeshejwe.
Inzitizi:
Ubushyuhe bwinshi cyane butera gushyuha, bigatuma habaho imyenge myinshi (hafi 5%–8%) no kudakomera cyane ku muvuduko mwinshi; kudakomera cyane mu bushyuhe bw'icyumba, no kudakomera ku ngaruka ntabwo ari byiza nka silicon carbide ifite silicon nitride.
2. Imiyoboro yo kurinda RBSiC
Hakoreshejwe uduce twa SiC na grafiti nk'ibikoresho fatizo, ibikoresho binyura mu nzira yo kwinjira muri silicon. Silicon y'amazi yinjira mu myenge, igakorana na graphite kugira ngo ikore SiC phase nshya, amaherezo igakora imiterere ivanze ya "SiC framework + silicon yigenga".
Ibiranga by'ingenzi:
Ubucucike bwinshi n'ubucucike buke:Silikoni y'ubuntu yuzuza imyenge, igabanya imyenge kugeza munsi ya 1%, bigatuma umwuka utagira umwuka mwinshi kandi udashobora gutwarwa n'umuvuduko mwinshi, ikwiriye gukoreshwa mu gihe cy'umuvuduko mwinshi n'igihe cy'ubushyuhe bwinshi.
uburyo bwo gufunga (nk'ibikoresho byo gushyushya umuriro).
Imiterere myiza ya mekanike:Ubushyuhe bwo mu cyumba bufite imbaraga za 250–400MPa, gukomera cyane mu kuvunika, no kudakora neza kurusha silicon carbide yasubiwemo.
Ubudahangarwa buri hagati mu bushyuhe bwinshi:Ubushyuhe bw'igihe kirekire mu gukora ni 1200°C. Hejuru ya 1350°C, silikoni yigenga irakoroha, bigatuma imbaraga zayo zigabanuka kandi ikagabanya imikorere yayo mu bushyuhe bwinshi.
Uburyo bwiza bwo gutunganya:Kuba hariho silikoni yigenga bigabanya ububobere bw'ibikoresho, bigatuma byoroha kuyikora mu buryo bugoye, bigatuma ikiguzi cyo kuyikora kiba gito cyane.
Inzitizi:
Umusaruro w'ubushyuhe bwinshi uterwa na silikoni yigenga, bigatuma idakoreshwa igihe kirekire hejuru ya 1350°C; silikoni yigenga ihita ikorana na alkali zikomeye, aluminiyumu ishongeshejwe, nibindi, bigatuma idashobora kwangirika.
3. Umuyoboro wo kurinda wa NSiSC
Ni ibintu bivanze bigizwe no guhuza uduce twa SiC muri matrix ya silicon carbide binyuze mu gukora Si₃N₄ nk'ikiciro cyo gufatanya binyuze mu buryo bwa nitriding.
Ibiranga by'ingenzi:
1. Ubudahangarwa ku bushyuhe bwinshi cyane:Ubushyuhe buke bushobora kwaguka cyane ndetse n'ubukomere bwinshi bw'igice cya Si₃N₄ gifatanye bituma umuyoboro w'uburinzi ushobora kwihanganira ubushyuhe n'ubukonje buri hejuru ya 1000℃ udacika bitewe n'impinduka zitunguranye z'ubushyuhe, bigatuma uba ukwiriye gukoreshwa mu bihe byo gukonja hamwe n'ihindagurika ry'ubushyuhe rikunze kubaho.
2. Ubudahangarwa bwiza bwo kwangirika:Irakomeye cyane mu kurwanya aside ikomeye, alkali zikomeye, ibyuma bishongeshejwe (nk'aluminium na umuringa), n'umunyu ushongeshejwe, bigatuma ikwiriye cyane ahantu hangiza ibintu mu nganda zikora imiti n'ibyuma.
3. Ingufu nyinshi za mekanike:Ingufu zo guhindagurika kw'ubushyuhe bw'icyumba zigera kuri 300–500 MPa, kandi imbaraga zigumana neza ku bushyuhe bwinshi kurusha ibikoresho bya SiC byuzuye, kandi zigakomera cyane mu kugongana.
4. Ubushyuhe bwo gukora:Ubushyuhe bw'igihe kirekire bwo gukora ni 1350℃, ubushobozi bwo kwihanganira ubushyuhe bw'igihe gito kugeza kuri 1500℃.
5. Uburyo bwiza bwo gukingira:Ibungabunga amashanyarazi neza ndetse no mu bushyuhe bwinshi, ikarinda ko ibimenyetso bya thermocouple bihungabana.
Inzitizi:
Ubudahangarwa bw'ingufu ni buke gato ugereranije na karubide ya silikoni yongeye gukoreshwa; gukoreshwa igihe kirekire mu kirere gishyushya ingufu bishobora gutuma urwego rw'ubuso bw'ingufu za olide rucika.
