Kev ruaj khov zoo heev nyob rau hauv kev kub hnyiab heev
Kev tiv thaiv mus sij hawm ntev rau ultraviolet hluav taws xob thiab atomic oxygen
Cov yam ntxwv qis tawm thiab kev sib raug zoo ntawm lub tshuab nqus tsev
Lub zog kho tshuab siab thiab hnav tsis kam thaum tswj cov qauv sib dua
Ib yam khoom siv hauv ib lub substrate yeej tsis tshua muaj peev xwm ua tau raws li tag nrho cov kev xav tau no tib lub sijhawm. Los ntawm kev muab cov zaj duab xis nyias nyias rau ntawm qhov chaw ntawm lub substrate, kev txhim kho kev ua tau zoo tuaj yeem ua tiav yam tsis tas hloov pauv tus qauv tsim tseem ceeb.
2. Cov txiaj ntsig tseem ceeb ntawm cov thev naus laus zis nqus tsev
Cov txheej txheem nqus tsev txheej txheej tso cov hlau, ceramic, lossis cov khoom sib xyaw rau ntawm cov substrates hauv qab qhov nqus tsev siab lossis huab cua tswj tau, tsim cov zaj duab xis nyias ua haujlwm nrog cov tuab tswj tau meej, cov qauv me me, thiab cov khoom hloov kho tau. Lawv cov txiaj ntsig tseem ceeb hauv kev siv dav hlau suav nrog:
Cov qauv zaj duab xis siab thiab siab ntom
Qhov chaw nqus tsev txo qhov kev ua qias tuaj, ua rau kom cov zaj duab xis ceev thiab ruaj khov dua.
Muaj zog nplaum zaj duab xis-substrate
Cov txheej txheem tso tawm lub cev lossis tshuaj lom neeg ua kom muaj kev sib txuas zoo, ua rau cov txheej txheem tiv taus cov xwm txheej kev pabcuam hnyav.
Cov khoom siv ua haujlwm tau zoo
Los ntawm kev tsim cov txheej txheej ntau txheej, qib, lossis sib xyaw ua ke, cov khoom siv kho qhov muag, hluav taws xob, thermal, thiab mechanical tuaj yeem raug kho kom raug.
3. Cov Txheej Txheem Txheej Txheem Sawv Cev thiab Cov Ntawv Thov Aerospace
Muaj ntau txoj kev siv tshuab nqus tsev uas tau siv dav hauv kev tsim khoom siv dav hlau thiab kev tiv thaiv cov khoom tseem ceeb:
PVD (Kev Tso Pa Tawm Hauv Lub Cev)
Feem ntau siv los tsim cov txheej txheem uas tiv taus kev hnav, tiv taus kev xeb, thiab kev sib txhuam tsawg xws li TiN, CrN, thiab DLC rau cov khoom siv kho tshuab, cov kabmob, thiab cov khoom sib dhos.
CVD (Kev Tso Pa Tshuaj Lom Zem)
Haum rau kev ua tiav cov txheej txheem sib xws ntawm cov qauv geometries nyuaj, suav nrog cov yeeb yaj kiab kub thiab tiv thaiv xws li SiC, SiO₂, thiab Al₂O₃.
Cov Txheej Txheem Ua Haujlwm Kho Qhov Muag
Cov txheej txheej cuam tshuam ntau txheej yog siv los ua kom pom cov nplaim tswj cua sov, cov yeeb yaj kiab cuam tshuam, thiab cov txheej txheem kho qhov muag tiv taus hluav taws xob rau sab nraud ntawm lub dav hlau thiab cov kab ke kho qhov muag.
4. Txij li Kev Tiv Thaiv Khoom Siv mus rau Kev Txhim Kho Kev Ua Haujlwm ntawm Qib System
Tus nqi ntawm cov txheej txheem nqus tsev txuas ntxiv mus rau qhov kev tiv thaiv ntawm qhov chaw, pab txhawb rau kev ua haujlwm ntawm lub dav hlau:
Lub neej ua haujlwm ntev dua ntawm lub voj voog
Txo qhov puas tsuaj ntawm cov khoom siv thiab kev poob haujlwm
Txhim kho kev ntseeg siab thiab kev nyab xeeb ntawm cov khoom tseem ceeb
Pab kom siv tau cov khoom siv engineering ntawm cov khoom siv lightweight siab heev
Thaum cov haujlwm hauv chaw dav hlau hloov zuj zus mus rau lub sijhawm ntev dua thiab qhov chaw nyob uas xav tau ntau dua, cov txheej txheem nqus tsev vacuum hloov pauv ntawm cov txheej txheem pabcuam mus rau cov khoom tseem ceeb hauv kev tsim cov khoom siv hauv chaw dav hlau.
5. Xaus Lus
Thaum kev tsim kho aerospace nce mus rau lub sijhawm ntawm kev tshawb nrhiav qhov chaw tob thiab cov kev xav tau kev ntseeg siab ntxiv, cov txheej txheem nqus tsev muab txoj hauv kev zoo, tswj tau, thiab ruaj khov rau kev txhim kho cov khoom siv spacecraft. Los ntawm kev koom ua ke cov ntaub ntawv tshawb fawb nrog kev tsim kho nto siab heev, cov txheej txheem nqus tsev nyias nyias muab kev txhawb nqa kev ua tau zoo rau spacecraft ua haujlwm hauv qhov chaw ib puag ncig hnyav.
