Nyob rau xyoo tas los no, cov txheej silicon carbide tau maj mam tau txais kev saib xyuas thiab kev siv ntau dua, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias, siab siab, hnav, xeb thiab lwm yam kev ua haujlwm hnyav, ntawm cov txheej silicone tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua rau qee qhov, cov txheej silicon carbide tau dhau los ua kev xaiv nrov ntawm lwm txoj hauv kev. Cov txheej silicon carbide, tseem hu ua carbon silicide, yog cov txheej uas tsis yooj yim hnav uas muaj carbon thiab silicon. Yog li, cov txheej no puas zoo? Cia peb tham txog peb cov lus xaus.
Ua ntej, ib qho zoo ntawm silicon carbide txheej yog tias nws muaj kev tiv thaiv zoo hnav. Hauv cov teb xws li tsheb ciav hlau ceev ceev, kev tsim tshuab, kev tsim pwm, aerospace thiab kev navigation, kev siv silicon carbide txheej hardness thiab hnav tsis kam tau zoo dua, yog li nws tuaj yeem txhim kho lub neej kev pabcuam thiab kev ua haujlwm ntev ntawm cov khoom siv. Rau cov tshuab thiab cov khoom siv uas yuav tsum tau khiav ntev, cov khoom siv silicified carbon txheej tuaj yeem txuag tau ntau tus nqi, vim nws tuaj yeem txo qhov hnav thiab tsim kua muag ntawm cov khoom, ntev lub neej kev pabcuam ntawm cov khoom siv, thiab txo cov nqi txij nkawm.
Qhov thib ob, cov txheej silicon carbide kuj muaj qee qhov kev tiv thaiv corrosion thiab oxidation. Hauv ntau yam acid, alkali thiab lwm yam corrosive media thiab qhov kub siab oxidation ib puag ncig, silicon carbide txheej yuav tsis pom tseeb corrosion thiab oxidation, yog li ntawd kom ntseeg tau tias cov khoom coated siv thiab zoo.
Ntxiv mus, qhov nplaum ntawm silicon carbide txheej yog muaj zog, tuaj yeem sib txuas nrog cov khoom coated kom ruaj khov thiab ntseeg tau. Hauv kev tsim khoom lag luam thiab kev tsim khoom, ua ib qho thev naus laus zis siab heev, nws kuj tseem tuaj yeem tsim cov duab kos thiab cov nto meej heev, kom ua tau raws li qhov xav tau ntawm qhov ceev ceev, cov duab zoo, cov kev xav tau zoo ntawm cov khoom tshwj xeeb.
Tau kawg, muaj qhov tsis zoo rau cov txheej txheem silicon carbide. Ua ntej tshaj plaws, tus nqi npaj ntawm cov txheej txheem carbon silicified siab, thiab kev siv nws xav tau cov thev naus laus zis siab, cov khoom siv siab thiab cov txheej txheem ua haujlwm siv sijhawm ntau, yog li nws tus nqi siab heev. Qhov thib ob, vim tias cov txheej txheem carbon silicified yog tsim rau ntawm qhov chaw ntawm cov khoom siv hauv daim ntawv ntawm cov tshuaj tiv thaiv, nws cov tuab thiab cov yeeb yaj kiab sib xws yooj yim cuam tshuam los ntawm ntau yam xws li cov txheej txheem tsim khoom, cov khoom siv qauv thiab qhov loj me, yog li nws tsis tuaj yeem hloov kho rau qee qhov xwm txheej tshwj xeeb.
Hauv kev xaus, silicon carbide txheej yog ib qho ntawm cov txheej txheem ua haujlwm siab thiab ntau yam. Nws muaj qhov zoo ntawm kev hnav tsis kam, kev tiv thaiv corrosion, siab hardness, oxidation tsis kam, muaj zog adhesion thiab lwm yam ntxwv, tab sis tib lub sijhawm, muaj cov nqi tsim khoom siab, tsis sib npaug zaj duab xis tuab thiab lwm yam tsis zoo. Txawm li cas los xij, piv nrog cov txheej txheem ib txwm muaj, silicon carbide txheej tau ua tiav zoo heev thiab nws daim ntawv thov tau maj mam nthuav dav. Nrog rau kev txhim kho tas mus li thiab kev tsim kho tshiab ntawm thev naus laus zis, nws ntseeg tau tias silicon carbide txheej yuav raug siv rau ntau qhov chaw thiab tsim ntau cov txiaj ntsig thiab tus nqi rau tib neeg.
