Nyob rau hauv lub sijhawm thaum kev lag luam aerospace nthwv dej tau cheb lub ntiaj teb thiab qis - cov hnub qub nyob hauv lub ntiaj teb muaj kev sib koom ua ke, satellite lightweighting tau dhau los ua tus yuam sij tseem ceeb rau kev tawg los ntawm kev lag luam hauv lub cev. Los ntawm cov nqi tso tawm mus rau hauv- kev ua haujlwm ntawm lub voj voog, txhua 1 kilogram ntawm qhov hnyav txo tsis tsuas yog txuag tau 30,000 txog 50,000 yuan hauv cov nqi xa tawm, tab sis tseem tso chaw rau kev thauj khoom, ncua lub satellite hauv - orbit lifespan, thiab txhim kho kev ua haujlwm ntawm orbital deployment. Hauv no "kev sib tw rau qhov hnyav txo" hauv qhov chaw tshawb nrhiav,titanium alloy, nrog nws cov yam ntxwv tshwj xeeb ntawm "lub teeb thiab lub zog", tau dhau los ua cov khoom tseem ceeb uas tsav lub teeb pom kev zoo ntawm satellites. Nyob rau hauv daim ntawv ntawm "qhov chaw hlau", nws yog reshaping lub industrial toj roob hauv pes ntawm satellite manufacturing thiab chaw launches. Tuam Tshoj lub Beidou-3 navigation satellites, los ntawm lub teeb yuag tsim, tau nqa ntau meej navigation payloads, ua kom tiav cov teeb liab kev pab cuam thoob ntiaj teb thiab dhau los ua ib tug piv txwv ntawm ib lub teeb yuag.
Hauv kev xaiv cov ntaub ntawv rau satellite lightweighting, titanium alloy stands vim nws cov khoom tshwj xeeb. Nws qhov ceev tsuas yog 57% ntawm cov hlau, thaum nws lub zog tensile yog 1.26 npaug ntawm siab - lub zog steel, tiag tiag ua tiav qhov sib npaug ntawm "lub teeb thiab lub zog". Tsis tas li ntawd, titanium alloy muaj kev hloov pauv zoo ib puag ncig thiab tuaj yeem tiv taus ntev - lub sij hawm yaig los ntawm lub zog ultraviolet rays thiab cosmic rays nyob rau hauv lub ultra- qhov kub thiab txias qhov chaw nqus tsev vacuum ib puag ncig, tswj cov txheej txheem stability yam tsis muaj kev cuam tshuam los ntawm corrosion los yog aging thiab yog li tswj nws cov kev ua tau zoo.
Cov ntaub ntawv thov tiag tiag ntxiv ua kom pom qhov hnyav txo tus nqi ntawm titanium alloy: Tom qab siv TB2 siab-lub zog titanium alloy corrugated plhaub qauv rau cov kabmob raj lub khob ntawm cov xov tooj cua tshiab, qhov hnyav tau txo los ntawm ib nrab piv rau cov khoom siv ib txwm siv, thaum lub load- cov kabmob muaj peev xwm nce 80%; Cov qauv tseem ceeb ntawm Beidou-3 navigation satellite feem ntau siv cov khoom siv hauv tsev high-purity titanium alloy, txo qhov hnyav los ntawm ntau dua 15% piv rau cov qauv aluminium alloy, yog li tso qhov chaw muaj txiaj ntsig rau cov khoom siv tseem ceeb.
Nrog rau txoj kev loj hlob tob ntawm aerospace teb, qhov kev thov rau satellite lightweighting yuav tau upgraded tas li, thiab titanium alloys kuj zoo siab txais tos ib tug dav daim ntawv thov.
Cov khoom siv tshiab txav mus rau kev ua haujlwm siab dua. Cov ntaub ntawv tshiab titanium alloys nrawm nrawm ntawm kev tshawb fawb thiab kev loj hlob. Qhov ceev ntawm cov khoom tshiab tuaj yeem txo qis qis dua 4.0g / cm³, lub zog siab tshaj 1800MPa, thiab nws muaj ntau dua thermal kuj thiab hluav taws xob tsis kam. Nws yuav haum rau qhov xwm txheej loj ntawm kev tshawb nrhiav qhov chaw tob thiab lub hnub- synchronous orbits.
Daim ntawv thov tau nkag mus rau hauv txhua qhov chaw. Titanium alloys yuav nthuav dav los ntawm cov khoom siv rau kev tswj xyuas thermal, ntim hluav taws xob, cov khoom siv kho qhov muag, thiab lwm yam, thiab qhov feem pua ntawm tag nrho cov ntawv thov satellite yuav tsum nce mus rau 15% -20%. Nyob rau tib lub sijhawm, hauv micro-satellites thiab nano- satellites, kev sib xyaw titanium alloy qauv yuav dhau los ua lub hauv paus, ua tiav "tus qauv - muaj nuj nqi" kev tsim qauv, ua kom yooj yim rau kev teeb tsa satellite thiab txo qhov hnyav.
Ntsuab thiab qis-carbon, thiab kev rov ua dua tshiab tau dhau los. Kev siv thev naus laus zis thiab rov siv dua tshiab ntawm aerospace-qib titanium alloys yog maj mam loj tuaj. Cov khoom siv titanium alloy ntawm cov khoom siv satellites tuaj yeem ua kom huv thiab rov ua dua rau re-kev tsim khoom, txo cov khoom siv raw thiab siv zog, uas yog nyob rau hauv txoj kab nrog ntsuab thiab qis- carbon kev loj hlob kev taw qhia ntawm kev lag luam aerospace, thiab txo cov nqi lag luam ntxiv.
