Titanium muaj kev sib raug zoo nrog aviation. Xyoo 1953, kev siv cov khoom siv titanium hauv lub cav nacelles thiab firewalls ntawm DC-T dav hlau cav los ntawm Douglas Aircraft Company cim qhov pib ntawm titanium daim ntawv thov aviation. Txij thaum ntawd los, titanium tau siv nyob rau hauv aviation rau ntau tshaj ib nrab xyoo pua. Titanium siv dav hauv aviation yog vim nws cov yam ntxwv tseem ceeb uas zoo rau kev siv dav hlau. Niaj hnub no, TOPTITECH yuav delve rau hauv cov laj thawj vim li cas cov khoom siv dav hlau yuav tsum suav nrog titanium alloys.
Taw qhia rau Titanium
Nws tsuas yog nyob rau xyoo 1948 uas DuPont hauv Tebchaws Meskas tau pib tsim cov sponge titanium loj siv txoj kev txo magnesium. Qhov no tau cim qhov pib ntawm kev lag luam titanium ntau lawm. Titanium alloys, nrog rau lawv lub zog siab, zoo heev corrosion kuj, thiab siab kub kuj, tau dav siv nyob rau hauv ntau yam teb.
Cov yam ntxwv ntawm Titanium
Lub zog muaj zog: Titanium tshaj txhuas alloys los ntawm 1.3 npaug, magnesium alloys los ntawm 1.6 npaug, thiab stainless hlau los ntawm 3.5 npaug, sawv ua tus yeej ntawm cov khoom siv hlau.
Siab Thermal Strength: Titanium tuaj yeem ua haujlwm ntawm qhov kub ntau ntau pua degrees siab dua li cov aluminium alloys, tso cai rau kev siv ntev ntawm qhov kub ntawm 450 txog 500 degree.
Superior Corrosion Resistance: Titanium nthuav tawm tsis kam rau cov kua qaub, alkalis, thiab atmospheric corrosion. Nws muaj qhov tshwj xeeb tiv thaiv pitting thiab kev nyuaj siab corrosion cracking.
Kev Ua Haujlwm Kub Kub Zoo Tshaj Plaws: Titanium alloys nrog cov ntsiab lus me me, xws li TA7, khaws qee qib ntawm plasticity txawm nyob ntawm -253 degree .
Tshuaj Reactivity: Titanium nthuav tawm cov tshuaj lom neeg ua haujlwm siab ntawm qhov kub thiab txias, tuaj yeem koom nrog tshuaj lom neeg nrog impurities xws li hydrogen thiab oxygen hauv huab cua, ua rau tsim cov txheej txheem tawv.
Tsawg Thermal Conductivity thiab Elastic Modulus: Titanium cov thermal conductivity yog kwv yees li ib feem plaub ntawm cov npib tsib xee thiab ib feem tsib ntawm cov hlau, thaum ntau yam titanium alloys pom qhov txo qis ntawm kwv yees li 50 feem pua hauv thermal conductivity piv rau cov ntshiab titanium. Lub elastic modulus ntawm titanium alloys yog kwv yees li ib nrab ntawm cov hlau.
Aircraft Applications ntawm Titanium Alloys
Titanium alloys feem ntau pom daim ntawv thov hauv kev tsim cov dav hlau thiab lub cav, suav nrog forged titanium ntxuam hniav, compressor discs, cav casings, tso tshuab, thiab cov txheej txheem xws li tis kab teeb. Aerospace daim ntawv thov cia siab rau lub zog siab, corrosion kuj, thiab qis-kub kev ua tau zoo ntawm titanium alloys rau tsim cov hlab ntsha siab, roj tso tsheb hlau luam, fasteners, ntsuas pluaj, lub moj khaum, thiab foob pob ua ntxaij casings. Titanium alloy nplooj ntawv tau ua haujlwm nyob rau hauv cov khoom siv satellites, lunar modules, manned spacecraft, thiab chaw shuttles, yooj yim rau kev tsim kho ntawm cov rooj sib txoos.
