Cov txheej txheem txheej silicon carbide yog ib txoj kev los tsim cov txheej silicon carbide rau ntawm qhov chaw ntawm cov khoom siv, feem ntau yog siv cov tshuaj lom neeg vapor deposition, physicochemical vapor deposition, yaj impregnation, plasma sib xyaw tshuaj lom neeg vapor deposition thiab lwm txoj hauv kev los npaj cov txheej silicon carbide, silicon carbide txheej muaj kev tiv thaiv kub siab, tiv thaiv corrosion, tiv thaiv oxidation, hnav tsis kam thiab lwm yam khoom zoo heev. Yog li ntawd, nws yog dav siv rau hauv qhov kub siab, siab siab, ib puag ncig nyuaj thiab lwm yam teb.
Qhov chaw kub siab yog ib qho tseem ceeb ntawm kev siv SIC txheej. Cov ntaub ntawv ib txwm muaj peev xwm raug kev nthuav dav, mos, hlawv, oxidation thiab lwm yam teeb meem ntawm qhov kub siab, tab sis cov txheej silicon carbide muaj kev ruaj khov kub siab thiab tuaj yeem tiv taus corrosion thiab thermal kev ntxhov siab hauv qhov chaw kub siab. Yog li ntawd, nws yog qhov ua tau siv SIC txheej thev naus laus zis ntawm qhov kub siab.
Thaum kub siab, SIC coatings siv tau rau hauv cov cheeb tsam hauv qab no:
Ua ntej, aerospace
Cov cav tshiab hauv qhov chaw, cov cav foob pob hluav taws thiab lwm yam khoom siv uas yuav tsum tau tiv taus qhov kub thiab txias siab tuaj yeem siv cov txheej silicon carbide los muab cov khoom zoo dua thiab hnav tsis kam. Tsis tas li ntawd, hauv thaj chaw loj, kev tshawb nrhiav ntiaj teb, satellite, thiab lwm yam, cov txheej silicon carbide kuj tseem siv tau los tiv thaiv cov khoom siv hluav taws xob thiab cov kab ke tswj hwm los ntawm kev kub siab thiab cov kab hluav taws xob me me.
Qhov thib ob, lub zog tshiab
Hauv thaj chaw loj ntawm lub cell zaus, silicon carbide txheej tuaj yeem muab kev hloov pauv ntawm lub cell siab dua thiab kev ruaj khov zoo dua, ntxiv rau, siv rau cov roj teeb kub siab thiab lwm qhov chaw tuaj yeem muab lub roj teeb lub neej thiab kev ua haujlwm zoo dua, tsav tsheb txoj kev loj hlob ntawm cov thev naus laus zis tshiab.
3. Kev lag luam hlau thiab hlau
Hauv kev lag luam hlau thiab hlau, hauv cov txheej txheem tsim khoom hauv qab qhov kub siab, cov cib ua kom sov, cov khoom siv refractory thiab lwm yam khoom siv nrog rau cov kav hlau, cov li qub thiab lwm yam khoom xav tau cov khoom siv kub siab, corrosion thiab hnav tsis kam, silicon carbide txheej tuaj yeem muab kev tiv thaiv zoo dua, txhim kho lub neej ua haujlwm ntawm cov khoom siv.
4. Kev Lag Luam Tshuaj
Hauv kev lag luam tshuaj lom neeg, kev siv cov txheej txheem silicon carbide tuaj yeem tiv thaiv cov khoom siv tshuaj los ntawm kev xeb, oxidation thiab kev cuam tshuam ntawm qhov kub thiab txias thiab siab, txhim kho lub neej ua haujlwm thiab kev nyab xeeb ntawm cov khoom siv. Hauv kev xaus, cov txheej txheem txheej txheem silicon carbide tuaj yeem siv rau ntau qhov chaw kub siab, los muab kev ua haujlwm zoo dua thiab lub neej ua haujlwm, yav tom ntej, nrog rau kev txhim kho tas mus li ntawm cov txheej txheem npaj silicon carbide, yuav muaj ntau qhov chaw siv cov txheej txheem txheej txheem silicon carbide.
