Cov khoom siv hauv qab kev sib txhuam, kev hnav thiab qhov kub thiab txias siab yog qhov xav tau ntau ntxiv, thiab qhov tshwm sim ntawm cov khoom siv sintered silicon carbide uas tsis muaj kev nias muab rau peb nrog kev daws teeb meem tshiab. Cov silicon carbide sintered silicon carbide uas tsis muaj kev nias yog cov khoom siv ceramic uas tsim los ntawm kev sintering silicon carbide hmoov hauv qab qhov siab qis lossis tsis muaj kev nias.
Cov txheej txheem sintering ib txwm muaj feem ntau xav tau kev siab siab, uas ua rau qhov nyuaj thiab tus nqi ntawm cov txheej txheem npaj ua haujlwm nce ntxiv. Kev tshwm sim ntawm txoj kev sintering silicon carbide tsis muaj kev siab tau hloov qhov xwm txheej no. Nyob rau hauv qhov xwm txheej ntawm tsis muaj kev siab, cov hmoov silicon carbide raug sib xyaw ua ke ntawm qhov kub siab los ntawm kev sib kis thermal thiab kev cuam tshuam ntawm qhov chaw los tsim cov khoom siv ceramic ntom ntom.
Cov silicon carbide sintered uas tsis muaj kev nias muaj ntau yam zoo. Ua ntej, cov khoom siv uas tau npaj los ntawm txoj kev no muaj qhov ceev ceev thiab cov qauv me me sib xws, uas txhim kho cov khoom siv kho tshuab thiab kev tiv thaiv kev hnav ntawm cov khoom siv. Qhov thib ob, tsis tas yuav muaj cov khoom siv siab ntxiv hauv cov txheej txheem sintering tsis muaj kev nias, uas ua rau cov txheej txheem npaj yooj yim dua thiab txo tus nqi. Tsis tas li ntawd, txoj kev sintering tsis muaj kev nias kuj tseem tuaj yeem ua tiav kev npaj cov khoom loj thiab cov duab nyuaj ntawm silicon carbide, thiab nthuav dav daim ntawv thov.
Cov ntaub ntawv silicon carbide sintered uas tsis muaj kev nias muaj ntau yam peev xwm hauv kev siv kub siab. Lawv tuaj yeem siv rau hauv cov qhov cub kub siab, cov sensors kub siab, cov khoom siv fais fab thiab aerospace. Vim nws qhov ruaj khov kub siab zoo heev, hnav tsis kam thiab thermal conductivity, cov ntaub ntawv silicon carbide sintered uas tsis muaj kev nias tuaj yeem tiv taus qhov kub thiab txias heev thiab cov xwm txheej ua haujlwm hnyav.
Txawm li cas los xij, tseem muaj qee qhov kev cov nyom hauv kev npaj cov txheej txheem ntawm cov silicon carbide uas tsis muaj siab sintering, xws li kev tswj qhov kub thiab lub sijhawm sintering, hmoov dispersion thiab lwm yam. Nrog rau kev txhim kho ntxiv ntawm thev naus laus zis thiab kev tshawb fawb tob tob, peb tuaj yeem cia siab tias yuav muaj kev siv dav thiab kev txhim kho ntxiv ntawm kev ua tau zoo ntawm cov txheej txheem sintering silicon carbide uas tsis muaj siab hauv thaj chaw ntawm cov ntaub ntawv kub siab.
Hauv kev xaus lus, silicon carbide sintered uas tsis muaj siab qhib lub sijhawm tshiab rau kev npaj cov khoom siv kub siab los ntawm kev ua kom yooj yim rau cov txheej txheem npaj, txhim kho cov khoom siv thiab nthuav dav ntau yam kev siv. Nrog rau kev txhim kho thev naus laus zis, cov khoom siv silicon carbide sintered uas tsis muaj siab yuav qhia txog lub peev xwm ntau dua hauv kev siv kub siab thiab coj ntau daim ntawv thov tshiab rau ntau yam kev lag luam.
