Kev kub tsis kam ntawm silicon carbide ceramics

Silicon carbide ceramics (SiC ceramics) yog ib hom khoom siv ceramic tshiab uas muaj qhov nyuaj siab, muaj zog heev thiab tiv taus kev hnav. Nws cov khoom tseem ceeb yog silicon carbide, thiab nws cov qauv siv lead ua muaj kev ruaj khov thermal thiab tshuaj lom neeg siab heev. Cov kev sim qhia tau tias silicon carbide ceramics tuaj yeem tswj tau kev ua haujlwm ruaj khov hauv qhov kub thiab txias heev, thiab nws qhov kev tiv taus kub zoo dua li cov khoom siv ceramic ib txwm muaj.

Raws li kev tshawb fawb, qhov kub thiab txias ntawm silicon carbide ceramics tuaj yeem ncav cuag ntau dua 2000 degrees Celsius. Thaum muaj qhov kub siab heev, silicon carbide ceramics tseem tswj tau cov khoom siv kho tshuab zoo thiab kev ruaj khov ntawm cov qauv, uas ua rau nws muaj ntau yam kev cia siab rau daim ntawv thov hauv qhov chaw kub siab.

Daim ntawv thov kev cia siab ntawm silicon carbide ceramics

1. Kev Tsim Kho Dav Hlau

Hauv kev lag luam aerospace, qhov chaw kub siab tsis zam tau. Qhov ruaj khov ntawm silicon carbide ceramics ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv kub siab xws li lub cav dav hlau thiab rocket thrusters.

2. Kev lag luam hluav taws xob thiab tshuaj lom neeg

Hauv kev lag luam fais fab thiab tshuaj lom neeg, cov reactors kub siab thiab cov cua sov sib hloov thiab lwm yam khoom siv muaj qhov xav tau siab rau qhov kub thiab txias ntawm cov ntaub ntawv. Qhov ruaj khov kub ntawm silicon carbide ceramics ua rau nws yog cov khoom siv xaiv rau cov khoom siv no

3. Cov tshuab siv hauv kev lag luam

Hauv kev lag luam ntawm cov tshuab ua haujlwm, qhov kub siab ruaj khov ntawm silicon carbide ceramics tuaj yeem txhim kho qhov hnav tsis kam thiab corrosion tsis kam ntawm cov khoom siv kho tshuab thiab txuas ntxiv lub neej kev pabcuam ntawm cov khoom siv.

Vim tias nws ruaj khov heev thaum kub thiab txias, silicon carbide ceramics muaj ntau yam kev siv. Nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, nws ntseeg tau tias kev siv silicon carbide ceramics yuav dav dua, ua rau tib neeg lub neej yooj yim dua thiab muaj kev vam meej ntau dua.
