Txheej silicon carbide yog dab tsi?

Txheej silicon carbide,Feem ntau hu ua SiC txheej, yog hais txog cov txheej txheem ntawm kev siv ib txheej ntawm silicon carbide rau ntawm qhov chaw los ntawm cov txheej txheem xws li Chemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), lossis thermal spraying. Cov txheej txheem silicon carbide ceramic no txhim kho cov khoom ntawm ntau yam substrates los ntawm kev muab kev tiv thaiv kev hnav zoo, kev ruaj khov thermal, thiab kev tiv thaiv corrosion. SiC paub txog nws cov khoom zoo tshaj plaws ntawm lub cev thiab tshuaj lom neeg, suav nrog lub ntsiab lus melting siab (kwv yees li 2700 ℃), qhov nyuaj heev (Mohs scale 9), kev tiv thaiv corrosion thiab oxidation zoo heev, thiab kev ua haujlwm ablation zoo heev.

Cov txiaj ntsig tseem ceeb ntawm Silicon Carbide Coating hauv Kev Siv Hauv Kev Lag Luam

Vim yog cov yam ntxwv no, silicon carbide txheej yog siv dav hauv cov teb xws li aerospace, riam phom, thiab semiconductor processing. Hauv cov chaw ib puag ncig hnyav, tshwj xeeb tshaj yog nyob rau hauv 1800-2000 ℃ ntau yam, SiC txheej qhia txog kev ruaj khov thermal thiab ablative tsis kam, ua rau nws zoo tagnrho rau cov ntawv thov kub siab. Txawm li cas los xij, silicon carbide ib leeg tsis muaj kev ruaj khov ntawm cov qauv tsim nyog rau ntau daim ntawv thov, yog li cov txheej txheem txheej txheem yog siv los siv nws cov khoom tshwj xeeb yam tsis muaj kev cuam tshuam rau lub zog ntawm cov khoom. Hauv kev tsim khoom semiconductor, silicon carbide coated elements muab kev tiv thaiv txhim khu kev qha thiab kev ua haujlwm ruaj khov hauv cov khoom siv siv hauv MOCVD cov txheej txheem.

Cov Txheej Txheem Siv Rau Kev Npaj Txheej Silicon Carbide

Ⅰ● Kev Txheej Txheem Silicon Carbide Uas Siv Tshuaj Lom Zem (CVD)

Hauv txoj kev no, SiC coatings yog tsim los ntawm kev muab cov substrates rau hauv chav tshuaj tiv thaiv, qhov twg methyltrichlorosilane (MTS) ua haujlwm ua ntej. Nyob rau hauv cov xwm txheej tswj hwm - feem ntau 950-1300 ° C thiab qhov siab tsis zoo - MTS dhau los ua decomposition, thiab silicon carbide raug tso rau ntawm qhov chaw. Cov txheej txheem CVD SiC coating no ua kom muaj cov txheej txheem ntom ntom, sib xws nrog kev sib txuas zoo heev, zoo tagnrho rau cov ntawv thov siab hauv semiconductor thiab aerospace sectors.

Ⅱ● Txoj Kev Hloov Pauv Ua Ntej (Polymer Impregnation thiab Pyrolysis - PIP)

Lwm txoj kev siv tshuaj tsuag silicon carbide zoo yog txoj kev hloov pauv precursor, uas yog kev muab cov qauv uas tau kho ua ntej tso rau hauv cov kua ceramic precursor. Tom qab nqus lub tank impregnation thiab nias lub txheej, cov qauv raug cua sov, ua rau cov txheej silicon carbide tsim thaum txias. Txoj kev no yog qhov nyiam rau cov khoom uas xav tau cov txheej tuab sib npaug thiab kev tiv thaiv kev hnav zoo dua.

Cov Khoom Siv Lub Cev ntawm Silicon Carbide Txheej

Cov txheej txheej silicon carbide muaj cov yam ntxwv uas ua rau lawv zoo tagnrho rau kev siv hauv kev lag luam uas nyuaj. Cov yam ntxwv no suav nrog:

Kev Ua Kub: 120-270 W / mK
Coefficient ntawm Thermal Expansion: 4.3 × 10 ^^(-6)/K (ntawm 20 ~ 800 ℃)
Kev Tiv Thaiv Hluav Taws Xob: 10 ^⁵– 10^⁶Ω·cm
Hardness: Mohs nplai 9

Cov ntawv thov ntawm Silicon Carbide Txheej

Hauv kev tsim khoom semiconductor, txheej silicon carbide rau MOCVD thiab lwm yam txheej txheem kub siab tiv thaiv cov khoom siv tseem ceeb, xws li reactors thiab susceptors, los ntawm kev muab ob qho tib si kub siab tiv taus thiab ruaj khov. Hauv kev tsav dav hlau thiab kev tiv thaiv, silicon carbide ceramic coatings yog siv rau cov khoom uas yuav tsum tiv taus kev cuam tshuam ceev ceev thiab cov chaw corrosive. Ntxiv mus, silicon carbide xim lossis coatings kuj tseem siv tau rau cov khoom siv kho mob uas xav tau kev ruaj khov nyob rau hauv cov txheej txheem sterilization.

Vim li cas thiaj xaiv Silicon Carbide Txheej?

Nrog cov ntaub ntawv pov thawj hauv kev ua kom lub neej ntawm cov khoom siv ntev dua, cov txheej txheej silicon carbide muab kev ruaj khov thiab kev ruaj khov ntawm qhov kub thiab txias, ua rau lawv pheej yig rau kev siv mus sij hawm ntev. Los ntawm kev xaiv cov nplaim silicon carbide coated, kev lag luam tau txais txiaj ntsig los ntawm kev txo cov nqi kho, kev txhim kho kev ntseeg siab ntawm cov khoom siv, thiab kev ua haujlwm zoo dua.
