Titanium thiab nws cov alloys yog hloov cov tsoos txhuas alloys hauv ntau daim ntawv thov aerospace. Niaj hnub no, kev lag luam aerospace siv txog 42 feem pua ntawm tag nrho lub ntiaj teb kev tsim khoom ntawm titanium cov ntaub ntawv, thiab txij li tam sim no mus rau 2010, qhov kev thov rau cov ntaub ntawv titanium yuav tsum tau nce ntxiv ntawm tus lej ob. Lub cim tshiab ntawm lub dav hlau yuav tsum ua kom tag nrho cov kev ua tau zoo los ntawm titanium alloy. Ob qho tib si kev lag luam thiab tub rog aircraft kev lag luam yog tsav qhov kev thov rau titanium alloy. Boeing 787, Airbus A380, F-22 Raptor fighter, F-35 Joint attack fighter (tseem hu ua xob laim II) thiab lwm cov qauv tshiab txhua tus siv ntau cov ntaub ntawv titanium alloy.
Qhov zoo ntawm titanium alloy cov ntaub ntawv
Titanium alloy muaj lub zog siab, siab tawg toughness, zoo corrosion kuj thiab weldability. Nrog rau kev siv cov ntaub ntawv sib xyaw ua ke hauv lub dav hlau dav hlau, qhov kev faib ua feem ntawm titanium raws li cov ntaub ntawv siv hauv lub dav hlau fuselage kuj yuav nce ntxiv, vim tias kev sib koom ua ke ntawm titanium thiab cov ntaub ntawv sib xyaw yog zoo dua li ntawm aluminium alloy. Piv txwv li, piv nrog aluminium alloy, titanium alloy tuaj yeem ua rau lub neej kev pab cuam ntawm lub fuselage qauv los ntawm 60 feem pua.
Lub zog siab heev / ceev piv ntawm titanium alloy (txog 20: 1, piv txwv li qhov hnyav txo qis rau cov neeg tsim qauv dav hlau. Tsis tas li ntawd, qhov muaj zog corrosion kuj ntawm titanium alloy (piv nrog hlau) tuaj yeem txuag tau tus nqi ntawm kev ua haujlwm txhua hnub thiab kev saib xyuas ntawm lub dav hlau.
Xav tau kev muaj peev xwm ua tau ntau dua
Vim tias nws nyuaj rau txheej txheem ntau dua li cov hlau alloy zoo tib yam, titanium alloy feem ntau suav tias yog ib qho nyuaj rau kev ua cov khoom siv. Cov hlau tshem tawm tus nqi ntawm cov titanium alloy feem ntau tsuas yog kwv yees li 25 feem pua ntawm cov hlau zoo tib yam lossis stainless hlau, yog li lub sij hawm yuav tsum tau ua cov titanium alloy workpiece yog li 4 npaug ntawm cov hlau.
Txhawm rau kom ua tau raws li qhov xav tau ntau ntxiv rau titanium alloy ua hauv kev lag luam aviation manufacturing, cov tuam txhab yuav tsum tau ua kom muaj peev xwm ntau lawm, yog li lawv yuav tsum nkag siab zoo dua cov txiaj ntsig ntawm titanium alloy ua cov tswv yim. Kev ua haujlwm ntawm titanium alloy workpiece pib los ntawm forging mus txog 80 feem pua ntawm cov khoom raug tshem tawm kom tau txais cov duab ua haujlwm kawg.
Nrog rau kev loj hlob sai ntawm kev lag luam aviation qhov chaw, manufacturers tau xav tias lawv tsis tuaj yeem ua qhov lawv xav tau. Tsis tas li ntawd, vim muaj kev xav tau ntau ntxiv vim qhov ua haujlwm qis ntawm titanium alloy workpieces, kev ua haujlwm muaj peev xwm ntawm titanium alloy yog pom tseeb hauv lub xeev nruj. Qee lub tuam txhab ua lag luam nyob rau hauv kev lag luam aviation manufacturing txawm qhib lo lus nug seb puas muaj peev xwm machining uas twb muaj lawm tuaj yeem ua tiav cov haujlwm ua haujlwm ntawm txhua qhov tshiab titanium alloy workpieces. Vim tias cov workpieces no feem ntau yog ua los ntawm cov alloys tshiab, nws yog ib qho tsim nyog los hloov cov txheej txheem ua thiab cov khoom siv.
