Kev siv ntawm CVD SiC txheej
CovCVD SiC txheejtxheej txheem yog dav siv nyob rau hauv ob peb industries vim nws versatility thiab kev ua tau zoo cov txiaj ntsig. Ib qho ntawm cov ntawv thov tseem ceeb yog nyob rau hauv kev tsim khoom semiconductor, qhov twg SiC-coated Cheebtsam pab tiv thaiv qhov muag muag thaum lub sijhawm ua wafer. CVD SiC-coated cov cuab yeej, xws li susceptors, rings, thiab wafer nqa, ua kom muaj qhov kub thiab txias thiab tiv thaiv kev sib kis thaum lub sijhawm tsim khoom tseem ceeb.
Hauv kev lag luam aerospace,CVD SiC txheejyog siv rau cov khoom uas raug tshav kub heev thiab mechanical stress. Cov txheej txheem txuas ntxiv lub neej ntawm turbine blades thiab combustion chambers, uas ua haujlwm hauv cov xwm txheej hnyav. Tsis tas li ntawd, CVD SiC feem ntau yog siv los tsim cov iav thiab cov khoom siv kho qhov muag vim nws cov khoom muaj kev cuam tshuam thiab thermal stability.
Lwm daim ntawv thov tseem ceeb ntawm CVD SiC yog nyob rau hauv kev lag luam tshuaj. Ntawm no, SiC coatings tiv thaiv cov khoom xws li cov khoom siv hluav taws xob, cov ntsaws ruaj ruaj, thiab cov twj tso kua mis los ntawm cov khoom corrosive. SiC nto tseem tsis muaj kev cuam tshuam los ntawm cov kua qaub thiab cov hauv paus, ua rau nws zoo tagnrho rau ib puag ncig uas muaj tshuaj lom neeg ua haujlwm tseem ceeb.
Cov yam ntxwv ntawm CVD SiC txheej
Cov khoom ntawm CVD SiC txheej yog dab tsi ua rau nws muaj txiaj ntsig zoo hauv cov ntawv thov no. Ib qho ntawm nws cov yam ntxwv tseem ceeb yog nws qhov hardness, nyob ze rau pob zeb diamond ntawm Mohs hardness nplai. Qhov hnyav hnyav no muab CVD SiC coatings zoo kawg nkaus tiv thaiv hnav thiab puas, ua rau lawv tsim nyog rau qhov chaw muaj kev sib txhuam.
Tsis tas li ntawd, SiC muaj cov thermal conductivity zoo heev, uas tso cai rau cov khoom siv coated los tswj lawv txoj kev ncaj ncees txawm tias nyob hauv qhov kub thiab txias. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev siv semiconductor thiab aerospace, qhov twg cov ntaub ntawv yuav tsum tiv taus cua sov thaum khaws cov khoom siv zog.
Cov tshuaj inertness ntawm CVD SiC txheej yog lwm qhov zoo dua. Nws tiv taus oxidation, corrosion, thiab tshuaj lom neeg cov tshuaj tiv thaiv nrog cov khoom hnyav, ua rau nws yog ib qho zoo tagnrho txheej rau cov khoom siv tshuaj. Ntxiv mus, nws cov coefficient tsawg ntawm thermal expansion kom ntseeg tau tias cov chaw coated khaws lawv cov duab thiab ua haujlwm txawm tias nyob rau hauv thermal cycling tej yam kev mob.

Hauv cov ntsiab lus, CVD SiC txheej muab cov khoom siv ruaj khov, kev ua haujlwm siab rau kev lag luam uas xav tau cov ntaub ntawv uas tuaj yeem tiv taus cua sov, kev ntxhov siab, thiab tshuaj lom neeg corrosion. Nws cov ntawv thov muaj ntau yam los ntawm kev tsim khoom semiconductor mus rau aerospace thiab tshuaj ua haujlwm, qhov twg cov khoom ntawm SiC - xws li hardness, thermal stability, thiab tshuaj tsis haum - yog qhov tseem ceeb rau kev ua haujlwm zoo. Raws li kev lag luam txuas ntxiv mus thawb cov ciam teb ntawm kev ua tau zoo thiab kev ntseeg siab, CVD SiC txheej yuav tseem yog ib qho tseem ceeb thev naus laus zis rau kev txhim kho cov khoom siv kom ruaj khov thiab siv tau ntev.
Los ntawm kev siv cov kws tshaj lij ntawm cov tuam txhab tshwj xeeb xws li vet-china, cov tuam txhab tuaj yeem tau txais cov txheej txheem zoo CVD SiC uas ua tau raws li qhov xav tau nruj ntawm cov txheej txheem kev lag luam niaj hnub no.
