Carbide ya silicon-reaction ni ubwoko bushya bwubukorikori buhanitse bwo mu buhanga, bufite imbaraga nyinshi, ubukana bwinshi, kurwanya neza kwambara no kurwanya ruswa, kandi bukoreshwa cyane muri metallurgie, peteroli-chimique, electronics, aerosmace nizindi nzego. Ibicuruzwa hamwe na silicon karbide abrasive auxiliary carbone umukara, grafite ninyongeramusaruro zitandukanye, ukoresheje gukanda byumye, gusohora cyangwa gusuka uburyo bwo gukora ubuziranenge, hanyuma ibikurikira hamwe kugirango dusobanukirwe nuburyo bwo gukora uburyo bwo gucumura karubide ya silicon!
Carbide ikora neza ya silicon Carbide Ivumburwa ni gahunda ya tekiniki ikuze nyuma yikigereranyo cyibihumbi byakozwe nuwahimbye imyaka myinshi kugirango ateze imbere ibikoresho fatizo nibikorwa byumusaruro, cyane cyane uburyo budasanzwe bwo gucumura.
Mu kirego cya 1 cyavumbuwe, igice cyibiro byifu ya silicon karbide ni 5 ~ 8, umukara wa karubone ni 0.5-1.5, grafite ni 1-1.5, naho binder ni 0.1-0.5. Muri byo, ingano yubunini bwa gradient ya silicon karbide ni sic (90-30m) ibice 3-5, sic) 30-0.8m) ibice 2-3. Methyl selulose na PVA ifu ya gazelle yashyizwe mumazi akwiye ibice 0.1-0.5, kandi igisubizo kiboneye cyabonetse nyuma yo gushyuha.
1. Kuvanga ubwoko bwose bwifu, ibifata nibisubizo byateguwe ukurikije formula hanyuma ukangure neza.
2, sukura icyuho cya casting vacuum, ugere kuri 0.1Mpa, inshinge zumuvuduko wavanze. Nyuma yigihe runaka, slurry irekurwa kandi ubusa burasohoka. Komeza kuri 30-70 mumasaha 18-20 kugirango wumuke.
3. Gerageza fagitire ukurikije ibisabwa gushushanya.
4, shyira reaction ya sintering bilet mumatanura, ongeramo uburemere bwibice 1-3 bya silicon yicyuma, gucumura vacuum. Inzira igabanijwemo ubushyuhe buke 0-700, ikomeza amasaha 3-5; Ubushyuhe bwo hagati 700-1400, komeza amasaha 4-6; Gumana ubushyuhe bwinshi 1400-2200 mumasaha 5-7. Kureka ubushyuhe buri munsi ya 150 uhagarike itanura hanyuma ukingure itanura.
5, gutunganya umucanga gusya ibicuruzwa hejuru ya silicon slag, hamwe no gusya.
6, ibicuruzwa bivura okiside mu itanura rya okiside, amasaha 24 kugeza 1350, gukonjesha bisanzwe. Kuramo, kugenzura no gushyira mububiko.
Ibikoresho fatizo hamwe nigipimo cyemejwe nuburyo bwavumbuwe ni siyanse kandi ishyize mu gaciro, kuburyo icyuho gifite icyuho gihagije naho icyuho gifite ubucucike bwiza; Igipimo cyiza cyo gushyushya igipimo, ubushyuhe no gufata umwanya byemeza imbaraga zo kugonda ibicuruzwa. Imikorere nyamukuru nubuziranenge bwubu buryo bugeze kurwego mpuzamahanga rwateye imbere. Ibipimo byingenzi byingenzi ni ibi bikurikira
Reaction sintering silicon karbide ishyirwa mubikorwa
Embodiment 1 Uburyo bwo gukora reaction-sinteri ya silicon karbide bundles:
1, ibikoresho fatizo byo gufata uburemere bufatika bwibice 0.3, ongeramo umubare munini wamazi aringaniye, uburemere bwibice 6.8 byifu ya karubide ya silicon (ingano ya 90-30m yibice 3.8, 30-0.8m yibice 3) , karubone umukara igice 1, umukara
2. . Nyuma yo kugera ku isaha 1, ibishishwa birarekurwa, hanyuma nyuma yamasaha 6, ikibumbano kikurwaho, ibikoresho bitagaragara bikavamo, icyumba cyo kumisha cyumye. 30-70, amasaha 18-20 yo gukuraho. 3. Mugihe cyo gusana icyuho, banza urebe niba icyuho cyujuje ibisabwa. Mugihe wujuje ibisabwa, sana ubusa ukurikije igishushanyo. Nyuma yo kugenzura, ohereza mucyumba cyo kumisha ubushyuhe bwo hejuru.
4. Ongeramo ibice 2.9 ibyuma bya silicon. Azote irashobora gushirwa mumashanyarazi. Igikorwa cyo gucumura kuri 700 ubushyuhe buke mumasaha 4; Ubushyuhe bwo hagati 1400, amasaha 5; Ubushyuhe bwo hejuru amasaha 2200,6. Iyo ubushyuhe bugabanutse amasaha 12 akagera kuri 150, hagarika imikorere mu itanura hanyuma ufungure itanura.
5. Nyuma yo gutunganya umucanga wumusenyi usohotse, urwego rwa silicon rusanzwe rwubatswe hejuru yubutaka kandi rusya hamwe n'umusenyi.
6. Intego yo kuvura okiside ni ugukuraho okiside ikorwa mugihe cyo gucumura. Ibicuruzwa bishyushya 1350 mumasaha 24 mumatara ya okiside hanyuma bikonjeshwa bisanzwe. Nyuma yo kuyikuraho, ishyirwa mububiko hakoreshejwe ubugenzuzi.
Ibikoresho fatizo hamwe nigipimo cyemejwe nuburyo bwavumbuwe ni siyanse kandi ishyize mu gaciro, kuburyo icyuho gifite icyuho gihagije naho icyuho gifite ubucucike bwiza; Igipimo cyiza cyo gushyushya igipimo, ubushyuhe no gufata umwanya byemeza imbaraga zo kugonda ibicuruzwa. Imikorere nyamukuru nubuziranenge bwibicuruzwa byakozwe nubu buryo bigeze ku rwego mpuzamahanga rwateye imbere.
Ibyavuzwe haruguru nuburyo bwo gutanga umusaruro wa silicon karbide ikora, niba ukeneye ibisobanuro byinshi, nyamuneka twandikire!
