Daim ntawv thov ntawm Titanium Tubes

Titanium alloy muaj lub zog siab thiab qhov chaw ntom ntom ntom, cov kws kho kom zoo, cov khoom siv zoo thiab corrosion tsis kam. Tsis tas li ntawd, titanium alloys muaj kev ua haujlwm tsis zoo thiab nyuaj rau kev txiav. Thaum lub sijhawm ua haujlwm kub, lawv nquag nqus cov impurities xws li hydrogen, oxygen, nitrogen, thiab carbon. Kuj tseem muaj kev hnav tsis zoo thiab cov txheej txheem ntau lawm. Kev lag luam ntawm titanium pib hauv xyoo 1948. Txoj kev loj hlob ntawm kev lag luam aviation yuav tsum muaj kev lag luam titanium loj hlob ntawm qhov nruab nrab txhua xyoo kev loj hlob ntawm kwv yees li 8%. Tam sim no, txhua xyoo ntawm titanium alloy ua cov ntaub ntawv nyob rau hauv lub ntiaj teb no tau mus txog ntau tshaj 40000 tons, nrog ze li ntawm 30 titanium alloy qib. Feem ntau siv titanium alloys yog Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7), thiab muaj ntshiab titanium (TA1, TA2). , thiab TA3).
Titanium alloy feem ntau yog siv los ua compressor Cheebtsam rau lub dav hlau xyaw, ua raws li cov qauv ntawm cov foob pob ua ntxaij, missiles, thiab high-ceev aircraft. Nyob rau nruab nrab -1960s, titanium thiab nws cov alloys twb tau siv nyob rau hauv kev lag luam dav dav rau kev lag luam electrodes hauv kev lag luam electrolysis, condensers hauv fais fab nroj tsuag, cua sov rau roj av refining thiab seawater desalination, thiab ib puag ncig muaj kuab paug tswj cov cuab yeej. Titanium thiab nws cov alloys tau dhau los ua cov khoom siv corrosion-resistant. Tsis tas li ntawd, nws kuj yog siv rau kev tsim cov khoom siv hydrogen cia thiab cov duab nco alloys.
Tuam Tshoj pib tshawb fawb txog titanium thiab titanium alloys hauv xyoo 1956; Hauv nruab nrab -1960s, kev tsim cov khoom siv titanium pib thiab TB2 alloys tau tsim.
Titanium alloy yog cov khoom siv tseem ceeb tshiab siv hauv kev lag luam aerospace, nrog rau lub ntiajteb txawj nqus, lub zog, thiab kev pabcuam kub ntawm txhuas thiab hlau. Txawm li cas los xij, nws muaj lub zog tshwj xeeb thiab ua haujlwm zoo heev rau seawater corrosion thiab ultra-low kub ua haujlwm. Xyoo 1950, Tebchaws Meskas thawj zaug siv cov khoom tsis muaj kabmob xws li cov khoom siv hluav taws xob hauv qab, cov ntaub thaiv npog cua, thiab cov ntaub thaiv npog rau ntawm F-84 fighter bombers. Pib txij xyoo 1960, kev siv cov titanium alloy hloov los ntawm lub fuselage rear mus rau nruab nrab lub fuselage, ib nrab hloov cov qauv hlau los tsim cov khoom tseem ceeb load-bearing Cheebtsam xws li thav duab, kab teeb, thiab tis slides. Kev siv titanium alloy hauv cov tub rog dav hlau tau nce sai, nce mus txog 20% ​​mus rau 25% ntawm lub dav hlau qhov hnyav. Pib txij xyoo 1970, cov dav hlau pej xeem tau pib siv ntau ntawm titanium alloy, nrog Boeing 747 aircraft siv ntau tshaj 3640 kilograms ntawm titanium. Kev siv titanium hauv cov dav hlau nrog Mach cov lej tsawg dua 2.5 feem ntau yog los hloov cov hlau thiab txo qhov hnyav ntawm cov qauv. Piv txwv li, US SR -71 high-altitude high-speed reconnaissance aircraft (yas ntawm Mach 3 thiab qhov siab ntawm 26212 meters), nrog rau titanium accounting rau 93% ntawm lub aircraft tus qauv hnyav, hu ua "tag nrho cov titanium. " aircraft. Thaum lub thrust rau qhov hnyav piv ntawm cov tshuab dav hlau nce los ntawm 4-6 rau 8-10, thiab qhov hluav taws xob kub ntawm lub compressor sib raug nce los ntawm 200-300 degree C mus rau 500-600 degree C, qis -pressure compressor discs thiab cov hniav thaum chiv thawj ua los ntawm txhuas yuav tsum tau hloov nrog titanium alloy, los yog titanium alloy yuav tsum tau siv es tsis txhob ntawm stainless hlau los tsim high-pressure compressor discs thiab hniav, thiaj li yuav txo qhov hnyav ntawm cov qauv. Nyob rau xyoo 1970, tus nqi ntawm titanium alloy siv nyob rau hauv aviation cav feem ntau suav txog 20% ​​mus rau 30% ntawm tag nrho cov qauv hnyav, feem ntau yog siv los tsim cov khoom siv compressor xws li forged titanium kiv cua, compressor discs thiab hniav, cam khwb cia titanium compressor casings, nruab nrab. casings, bearing shells, thiab lwm yam. Spacecraft mas siv lub siab tshwj xeeb lub zog, corrosion kuj, thiab kub tsis kam ntawm titanium alloy los tsim ntau yam siab hlab ntsha, roj tso tsheb hlau luam, fasteners, ntsuas straps, thav ntawv, thiab foob pob ua ntxaij plhaub. Artificial Earth satellites, lunar modules, manned spacecraft, thiab chaw shuttles kuj siv titanium alloy phaj vuam Cheebtsam.
