Kev piav qhia
Spacecraft yog cov tsheb nyuaj tsim los rau kev tshawb nrhiav chaw, xa xov tooj cua, thiab kev ua haujlwm tshawb fawb. Ferrotungsten muaj cov khoom tshwj xeeb uas ua rau nws muaj txiaj ntsig hauv kev tsim kho dav hlau, pab txhawb rau lawv cov kav ntev, kev ua tau zoo, thiab kev ntseeg siab hauv qhov xav tau ntawm qhov chaw.
Ib qho ntawm cov kev siv tseem ceeb ntawm ferrotungsten hauv kev tsim khoom siv dav hlau yog hauv kev tsim cov khoom siv hluav taws xob. Cov ntaub thaiv cua sov yog cov khoom tseem ceeb uas tiv thaiv lub dav hlau los ntawm cov cua kub hnyav uas tshwm sim thaum huab cua rov nkag. Ferrotungsten lub siab melting point, kub tsis kam, thiab lub zog ua rau nws haum rau siv nyob rau hauv cov ntaub thaiv npog. Kev suav nrog ferrotungsten txhim kho lub peev xwm ntawm lub tshav kub tiv thaiv kom tiv taus qhov kub thiab txias, tiv thaiv lub dav hlau los ntawm kev kub hnyiab thaum rov nkag thiab ua kom muaj kev nyab xeeb ntawm cov neeg coob thiab cov khoom siv.
Tsis tas li ntawd, ferrotungsten tuaj yeem siv rau hauv kev tsim cov khoom siv hauv lub dav hlau. Cov khoom siv, xws li cov thav duab, kev txhawb nqa, thiab cov vaj huam sib luag, muab qhov tsim nyog lub zog thiab nruj kom tiv taus lub zog uas tau ntsib thaum lub sijhawm tso tawm, qhov chaw mus ncig, thiab tsaws. Ferrotungsten lub zog siab, nruj, thiab tsis kam rau thermal expansion ua rau nws muaj txiaj ntsig hauv kev tsim cov khoom no. Kev suav nrog ferrotungsten txhim kho cov qauv kev ncaj ncees ntawm lub dav hlau, ua kom nws muaj peev xwm tiv taus cov neeg kho tshuab kev ntxhov siab, kev vibrations, thiab kub hloov pauv tau ntsib nyob rau ntau theem ntawm lub luag haujlwm.

Tsis tas li ntawd, ferrotungsten tuaj yeem siv rau hauv kev tsim hluav taws xob sib txuas thiab cov khoom sib txuas hauv lub dav hlau. Kev sib cuag hluav taws xob thiab cov khoom sib txuas yog qhov tseem ceeb rau kev xa hluav taws xob thiab cov teeb liab ntawm cov tshuab sib txawv thiab cov khoom siv hauv lub dav hlau. Ferrotungsten lub siab hluav taws xob conductivity thiab corrosion kuj ua rau nws muaj txiaj ntsig hauv kev tsim cov khoom no. Kev suav nrog ferrotungsten ua kom muaj txiaj ntsig zoo thiab txhim khu kev qha hluav taws xob sib txuas, txo cov teeb liab poob thiab tiv thaiv corrosion, txawm tias nyob rau hauv qhov chaw huab cua.
Hauv cov ntsiab lus, ferrotungsten plays lub luag haujlwm tseem ceeb hauv kev tsim khoom siv dav hlau. Nws siv nyob rau hauv cov tshav kub shields txhim khu lub spacecraft lub peev xwm los tiv thaiv lub kub hnyav thaum lub sij hawm atmospheric rov nkag. Tsis tas li ntawd, nws qhov kev suav nrog hauv cov khoom siv txhim kho lub dav hlau lub zog thiab kev nruj, ua rau nws tuaj yeem tiv taus lub zog thiab qhov kub thiab txias hloov pauv thaum lub sijhawm tso tawm, chaw mus ncig, thiab tsaws. Tsis tas li ntawd, ferrotungsten lub siab hluav taws xob conductivity thiab corrosion kuj ua rau nws muaj txiaj ntsig hauv kev tsim hluav taws xob thiab cov khoom sib txuas, kom ntseeg tau tias muaj zog thiab txhim khu kev qha thiab cov teeb liab xa mus rau hauv lub dav hlau.
