Kev Ua Haujlwm Dav Hlau: Kev Nrhiav Kev Sib Tw thiab Kev Ua Haujlwm Siab
Kev lag luam aerospace muaj cov kev xav tau siab heev rau cov ntaub ntawv, uas tsis yog tsuas yog yuav tsum tau sib dua txaus kom txo qhov hnyav ntawm lub dav hlau, tab sis kuj muaj lub zog zoo heev thiab tiv taus kub. Qhov qis qis thiab lub zog tshwj xeeb ntawm silicon carbide ceramics ua rau lawv yog cov khoom siv zoo tshaj plaws rau kev tsim cov khoom siv cav dav hlau thiab cov khoom siv dav hlau. Xav txog tias nyob rau hauv qhov kub thiab txias siab ntawm lub cav dav hlau, cov hniav turbine thiab cov khoom siv combustion chamber ua los ntawm silicon carbide ceramics tsis tsuas yog tuaj yeem tiv taus qhov kub thiab txias heev, tab sis kuj pab lub cav txhim kho kev ua haujlwm thiab txo kev siv zog nrog qhov hnyav sib dua. Nws puas tsis zoo kawg? Ntxiv mus, nws qhov kev ruaj khov thermal zoo heev tuaj yeem ua kom ntseeg tau tias cov khoom yuav tsis deform lossis puas tsuaj vim qhov kub hloov pauv thaum lub dav hlau tsim ntau qhov kub thaum lub dav hlau khiav ceev ceev, muab kev tiv thaiv rau kev nyab xeeb ntawm kev ya dav hlau.
Kev Tsim Khoom Siv Semiconductor: Kev Txhawb Nqa Tseem Ceeb rau Cov Txheej Txheem Precision
Kev tsim khoom semiconductor yog ib qho teb uas yuav tsum tau ua tib zoo thiab ua tau zoo ntawm cov khoom siv. Silicon carbide ceramics ua lub luag haujlwm tseem ceeb hauv cov khoom siv semiconductor vim lawv qhov nyuaj siab, coefficient nthuav dav thermal qis, thiab kev ruaj khov tshuaj zoo heev. Hauv cov txheej txheem tseem ceeb xws li photolithography thiab etching, wafer carriers thiab precision fixtures ua los ntawm silicon carbide ceramics tuaj yeem ua kom muaj qhov chaw siab ntawm silicon wafers thaum lub sijhawm ua tiav, ua kom muaj qhov tseeb ntawm kev tsim khoom chip. Tib lub sijhawm, nws txoj kev tiv thaiv corrosion rau ntau yam tshuaj reagents thiab plasmas ntev lub neej kev pabcuam ntawm cov khoom siv, txo cov nqi tsim khoom, thiab txhawb kev txhim kho tas mus li ntawm cov thev naus laus zis semiconductor mus rau qhov me me thiab kev ua tau zoo dua.
Kev lag luam hluav taws xob: daws cov teeb meem ntawm qhov kub thiab txias siab thiab xeb
Hauv kev lag luam fais fab, txawm tias nws yog lub zog thermal ib txwm muaj, kev lag luam tshuaj lom neeg, lossis lub zog nuclear thiab hnub ci tshiab, lawv txhua tus ntsib teeb meem ua haujlwm nyuaj xws li kub thiab xeb. Hauv cov boilers rau kev tsim hluav taws xob thermal, lub qhov cub hluav taws xob thiab cov khoom siv hloov pauv cua sov ua los ntawm silicon carbide ceramics tuaj yeem tiv taus kev yaig ntawm cov nplaim taws kub thiab cov pa roj corrosive, txhim kho kev ua haujlwm zoo thiab kev ntseeg siab ntawm cov khoom siv; Hauv kev lag luam nuclear, silicon carbide ceramics yog siv rau hauv cov roj cladding, cov ntaub ntawv qauv, thiab lwm yam ntawm nuclear reactors vim lawv qhov kub thiab txias zoo heev thiab kev tiv thaiv hluav taws xob, ua kom muaj kev nyab xeeb thiab ruaj khov ntawm cov tshuaj tiv thaiv nuclear; Hauv kev lag luam photovoltaic hnub ci, silicon carbide ceramics tuaj yeem siv los tsim cov khoom siv thauj khoom hauv cov cub tawg kub, txhawb nqa kev ua cov ntaub ntawv xws li silicon wafers hauv qhov chaw kub thiab txias, thiab pab txhim kho kev hloov pauv hluav taws xob hnub ci.
Kev ua haujlwm kho tshuab: lav qhov hnav tsis kam thiab siab precision
Hauv kev ua cov khoom siv kho tshuab, qhov nyuaj thiab hnav tsis kam ntawm silicon carbide ceramics ua rau nws yog cov khoom siv zoo rau kev tsim cov cuab yeej txiav, cov cuab yeej sib tsoo, cov kabmob thiab lwm yam khoom. Thaum peb siv cov cuab yeej txiav silicon carbide ceramic los txiav cov khoom siv hlau, lawv tuaj yeem yooj yim daws cov zog txiav siab, tswj qhov ntse ntawm cov hniav, txhim kho kev ua haujlwm zoo thiab qhov tseeb, txo cov cuab yeej hnav thiab hloov zaus. Silicon carbide ceramic bearings, nrog lawv cov coefficient sib txhuam qis thiab rigidity zoo, tuaj yeem ua haujlwm ruaj khov, txo kev siv hluav taws xob, thiab txuas ntxiv lub neej kev pabcuam ntawm cov khoom siv kho tshuab tig ceev ceev, muab kev txhawb nqa zoo rau kev txhim kho kev lag luam tsim khoom siv kho tshuab.
Cov khoom siv silicon carbide ceramics, nrog nws cov kev ua tau zoo heev, tau pom lawv tus kheej theem hauv ntau qhov chaw lag luam, thiab nrog kev nce qib tas mus li ntawm thev naus laus zis, nws cov kev cia siab rau daim ntawv thov yuav dav dua, txhaj tshuaj tshiab rau hauv kev txhim kho ntawm ntau yam lag luam.
