Qee qhov tseem ceeb ntawm kev siv titanium hauv kev lag luam aerospace:
Yuav ua li cas aerospace titanium siv nyob rau hauv dav hlau?
Vim tias nws lub teeb yuag thiab lub zog siab, titanium yog qhov tsim nyog rau kev tsim cov khoom sib txawv ntawm lub dav hlau, nrog rau lub cav rings, fasteners, tis tawv, tsaws iav, thiab lwm yam khoom siv.
Siab zog-rau-qhov hnyav piv
Ib qho ntawm qhov zoo tshaj plaws ntawm aerospace titanium alloys yog lawv qhov zoo tshaj plaws lub zog-rau-qhov hnyav piv. Titanium muaj zog npaum li ntau cov hlau tab sis tsuas yog 60% tuab li hlau. Cov cuab yeej no tso cai rau kev tsim cov khoom hnyav tsis tau muaj zog dav hlau, uas yog qhov tseem ceeb rau kev txhim kho roj efficiency thiab tag nrho kev ua tau zoo.
Corrosion kuj
Aerospace titanium alloys muaj zoo heev corrosion kuj. Qhov kev tiv thaiv ib puag ncig xws li ya raws thiab ntsev hauv huab cua ua kom lub neej ntev thiab kev ntseeg siab ntawm cov khoom siv dav hlau. Corrosion-resistant cov ntaub ntawv tseem ceeb tshwj xeeb tshaj yog rau cov dav hlau uas raug cuam tshuam los ntawm ntau yam huab cua.
Kev kub siab ua haujlwm
Titanium alloys khaws lawv cov cuab yeej cuab tam ntawm qhov kub siab, uas yog qhov tseem ceeb rau cov khoom siv ua haujlwm ntawm qhov kub siab heev uas tsim los ntawm cov tshuab dav hlau. Kev muaj peev xwm tiv taus qhov kub thiab txias yam tsis muaj kev cuam tshuam kev ua haujlwm tseem ceeb ua kom muaj kev nyab xeeb thiab ua haujlwm ntawm cov khoom tseem ceeb no.
Kev qaug zog
Titanium alloys paub txog lawv qhov qaug zog tiv thaiv, uas yog qhov txo qis hauv lub zog uas tshwm sim thaum cov khoom raug rau kev thauj khoom cyclic. Cov cuab yeej no yog qhov tseem ceeb rau cov khoom siv, xws li tsaws iav, uas raug kev nyuaj siab dua thaum txhua lub davhlau. Kev qaug zog tsis kam ntawm titanium alloys txhawb nqa tag nrho kev nyab xeeb thiab lub neej ntev ntawm lub dav hlau.
Dab tsi ntawm titanium yog siv nyob rau hauv dav hlau?
Ntau qib ntawm titanium yog siv nyob rau hauv kev lag luam aerospace, nyob ntawm seb cov kev cai tshwj xeeb ntawm kev cai titanium khoom tivthaiv lossis cov qauv. Ob qib feem ntau siv yog:
Qib 5 (Ti-6Al-4V)
Qib 5 titanium, tseem hu ua Ti-6Al-4V, yog cov titanium alloy feem ntau siv hauv aerospace. Nws yog tsim los ntawm 90% titanium, 6% aluminium, thiab 4% vanadium. Cov hlau sib txuas ua ke muaj zog, tiv thaiv corrosion, thiab tshav kub tsis kam.GR5 titanium ntawv feem ntau yog siv los tsim cov khoom siv dav hlau, cov khoom siv cav, thiab cov fasteners vim nws cov khoom zoo heev.
Qib 2 (Ti-CP)
Qib 2 titanium alloy, tseem hu ua Ti-CP (ua lag luam ntshiab titanium), yog cov ntshiab titanium alloy nrog cov ntsiab lus tsawg heev ntawm alloying ntsiab. Nws tau txais txiaj ntsig zoo rau nws cov kev tiv thaiv corrosion zoo heev thiab yog qhov zoo tagnrho rau kev tsim khoom ntawm cov khoom raug rau qhov chaw hnyav. Qib 2 titanium alloys, xws li GR2 titanium ntawv, feem ntau yog siv nyob rau hauv aircraft Cheebtsam uas corrosion yog ib qho teeb meem ntau, xws li fasteners, tsaws iav, thiab pa system.
