Thaum koj cov txheej txheem kev lag luam xav tau qhov kub thiab txias siab heev, kev siv hluav taws xob zoo, thiab lub neej ua haujlwm ntev, cov cua sov silicon carbide (SiC) sawv tawm ua qhov kev hloov kho tshiab tshaj plaws ntawm cov khoom siv cua sov hlau ib txwm muaj. Tsim los ntawm cov hmoov SiC ntshiab siab sintered ntawm 2200 ° C, peb cov khoom siv cua sov SiC xa cov cua sov txhim khu kev qha, sib xws rau cov chaw ib puag ncig hnyav uas cov cua sov hlau sai sai sag, oxidize, lossis ua tsis tiav.
Kev Ua Haujlwm Kub Siab Tsis Sib Xws
Peb cov cua sov SiC ua haujlwm tas li ntawm600 ° C txog 1450 ° C(nce mus txog1600°C), tshaj qhov txwv 1200 ° C ntawm feem ntau cov hlau alloys. Nrog rau kev ua kom sov zoo heev, lawv ua kom sov sai thiab faib cov cua sov sib npaug, tshem tawm cov kub kub thiab ua kom muaj kev tswj qhov kub kom raug - qhov tseem ceeb rau cov khoom zoo sib xws. Tsis zoo li cov hlau uas deform ntawm qhov kub heev, SiC tswj cov qauv ruaj khov, tiv taus creep thiab thermal shock rau kev ua haujlwm ruaj khov mus sij hawm ntev.
Kev Ruaj Khov & Kev Txhim Kho Kev Txuag Nyiaj
Kev tiv thaiv oxidation thiab corrosion txhais tau tias peb cov cua sov SiC. Lawv tiv taus acidic, alkaline, thiab reactive atmospheres, nrog rau qeeb qeeb laus uas ntev lub neej kev pabcuam.Ntev dua 3–5 zaugdua li cov cua sov hlau. Qhov no txo cov kev hloov pauv ntau zaus, txiav lub sijhawm tsis tau npaj tseg, thiab txiav cov nqi kho kom txog li50%Kev tsim tshwj xeeb uas tsis tshua muaj zog tiv thaiv qhov kub dhau, ua rau muaj kev nyab xeeb thiab kev ua haujlwm zoo dua.
Kev Siv Hluav Taws Xob Zoo & Kev Siv Dav Dav
Raws li cov cua sov uas tsis yog hlau uas txuag hluav taws xob, lawv hloov pauv yuav luag100% ntawm hluav taws xob rau hauv cua sov, txo cov khib nyiab thiab txo cov nqi ua haujlwm. Zoo tagnrho rau kev ua cov khoom siv ceramic sintering, iav yaj, kev kho cua sov hlau, thiab cua sov rau lub cub tawg hauv kev lag luam, peb cov cua sov SiC muaj ntau yam duab -GD, CD, U-hom, thiab cov qauv tsim tshwj xeeb—kom haum rau ntau hom cub tawg.
Vim li cas thiaj xaiv peb cov cua sov SiC?
Txhim kho koj lub cub tawg nrog peb cov cua sov SiC zoo tshaj plaws hnub no - cov nqi hluav taws xob qis dua, kev kaw tsawg dua, thiab cov khoom lag luam zoo duaTiv tauj peb tam sim no kom tau txais kev hais nqe dawb thiab kev sab laj txog kev siv tshuab!
