Silicon carbide coj yuav luag zoo li lub pob zeb diamond. Nws tsis yog tsuas yog lub teeb pom kev zoo tshaj plaws, tab sis kuj yog cov khoom siv hluav taws xob nyuaj tshaj plaws thiab muaj cov khoom nthuav tsis tshua muaj zog thiab yog tiv taus cov kua qaub heev thiab lyes.
Nrog silicon carbide ceramics cov khoom siv nyob twj ywm tas li kom kub siab txog qhov kub siab saum toj no 1,400 ° C. Lub siab Modulus> 400 GPA kom paub meej qhov seem ruaj khov. Cov khoom siv no ua rau Silicon Carbide predestined rau kev siv ua cov khoom tsim khoom. Silicon carbide masters corrosion, puas tsuaj thiab yaig raws li qhov ua tau zoo li nws sawv los txhuam hnav. Cheebtsam yog siv hauv cov nroj tsuag tshuaj lom neeg, cov mills, nthuav dav thiab cov extruders lossis li nozzles, piv txwv.
"Cov variants ssic (sintered silicon carbide) thiab sitic (silicon infiltrated silicon carbide) tau tsim lawv tus kheej."
Silicon carbide yog tshuaj lom neeg muaj kev nyab xeeb thiab tuaj yeem siv rau hauv kev lag luam khoom noj. Lwm daim ntawv thov rau Silicon Carbide Cheebtsam yog dynamic sealing thev naus laus zis siv kev sib txhuam thiab cov khoom siv tshuab ua piv txwv, cov khoom siv tshuab hauv cov twj thiab tsav cov tshuab. Piv rau cov hlau, silicon carbide pab tau cov kev daws teeb meem ntev dua thaum siv nrog kev siv xov xwm ntev, siab-kub. Silicon carbide ceramics kuj zoo tagnrho rau siv nyob rau hauv kev xav tau cov xwm txheej hauv kev ua kom zoo nkauj, tshuaj lom neeg tsim khoom thiab raws li cov yeeb nkab system.
Cov lus pom zoo li Silicon carbide, tseem hu ua Siliconized silicon carbide lossis sitic carbide uas yog hom ntxaij carbon los yog graphite nrog cov ntshav siticon. Vim tias sab laug hla txoj cai ntawm silicon, cov kev txiav txim siab sib dhos silicon carbide feem ntau hu ua Siliconized silicon carbide, lossis nws cov lus luv luv.
Yog tias muaj cov khoom noj cua daj cua dub yog tsim los ntawm Sintering of Silicon Carbide hmoov, nws feem ntau muaj cov tshuaj lom neeg hu ua cov txheej txheem SININING los ntawm kev cia cov sintering kub. Hom silicon carbide no feem ntau hu ua sintered silicon carbide, lossis sau cov ssic.
Silicon carbide hmoov tau nce los ntawm silicon carbide tsim raws li tau piav qhia hauv tsab xov xwm silicon carbide.
