Cov khoom siv nyob rau hauv kev sib txhuam, hnav thiab kub ib puag ncig yog qhov xav tau ntau ntxiv, thiab qhov tshwm sim ntawm cov ntaub ntawv xovxwm-dawb sintered silicon carbide muab peb cov kev daws teeb meem tshiab. Pressureless sintered silicon carbide yog cov khoom siv ceramic tsim los ntawm sintering silicon carbide hmoov nyob rau hauv qis siab lossis tsis muaj kev kub ntxhov.
Cov txheej txheem sintering ib txwm xav tau kev kub siab, uas ua rau muaj kev nyuaj siab thiab tus nqi ntawm cov txheej txheem npaj. Qhov tshwm sim ntawm cov txheej txheem tsis-siab sintering silicon carbide tau hloov qhov xwm txheej no. Nyob rau hauv qhov xwm txheej tsis muaj qhov siab, silicon carbide hmoov yog ua ke ntawm qhov kub thiab txias los ntawm thermal diffusion thiab cov tshuaj tiv thaiv saum npoo los tsim cov khoom siv ceramic ntom ntom.
Sintered silicon carbide tsis muaj siab muaj ntau yam zoo. Ua ntej, cov khoom tau npaj los ntawm hom no muaj qhov siab ceev thiab cov teeb tsa microstructure, uas txhim kho cov khoom siv tshuab thiab hnav tsis kam ntawm cov khoom. Qhov thib ob, tsis tas yuav tsum muaj cov cuab yeej siv siab ntxiv hauv cov txheej txheem sintering, uas yooj yim rau kev npaj thiab txo tus nqi. Tsis tas li ntawd, txoj kev uas tsis yog-siab sintering tuaj yeem paub qhov kev npaj ntawm qhov loj thiab cov duab ntawm cov khoom siv silicon carbide, thiab nthuav dav daim ntawv thov teb.
sintered silicon carbide cov ntaub ntawv uas tsis muaj siab muaj ntau yam muaj peev xwm nyob rau hauv high kub daim ntaub ntawv. Lawv tuaj yeem siv rau hauv qhov cub kub, kub sensors, khoom siv fais fab thiab aerospace. Vim nws zoo heev kub stability, hnav tsis kam thiab thermal conductivity, xovxwm-dawb sintered silicon carbide cov ntaub ntawv tuaj yeem tiv taus qhov kub thiab txias thiab ua haujlwm hnyav.
Txawm li cas los xij, tseem muaj qee qhov kev sib tw hauv kev npaj cov txheej txheem uas tsis yog-siab sintering silicon carbide, xws li tswj sintering kub thiab sij hawm, hmoov dispersion thiab lwm yam. Nrog rau kev txhim kho ntxiv ntawm thev naus laus zis thiab kev tshawb fawb tob, peb tuaj yeem cia siab tias yuav siv dav hauv daim ntawv thov thiab kev txhim kho ntxiv ntawm kev ua haujlwm tsis muaj zog sintering silicon carbide txoj hauv kev ntawm cov ntaub ntawv kub.
Hauv cov ntsiab lus, uas tsis yog-siab sintered silicon carbide qhib lub sijhawm tshiab rau kev npaj cov ntaub ntawv kub kub los ntawm kev ua kom yooj yim rau cov txheej txheem kev npaj, txhim kho cov khoom siv thiab nthuav dav daim ntawv thov ntau yam. Nrog rau kev txhim kho thev naus laus zis, cov ntaub ntawv tsis muaj zog sintered silicon carbide yuav pom muaj peev xwm ntau dua hauv cov ntawv thov kub thiab ua rau muaj kev siv tshiab tshiab rau ntau yam lag luam.
