Kev xaiv thiab kev txhim kho cov khoom siv aeronautical yog qhov tseem ceeb rau kev tsim cov nqi thiab tag nrho cov kev ua tau zoo ntawm cov dav hlau lub cev qauv. Saib rov qab rau ntawm keeb kwm, Tuam Tshoj tsuas yog tso siab rau kev ua yeeb yam hauv thaj teb ntawm cov khoom siv aviation nyob rau thaum ntxov, thiab yog li feem ntau ntawm cov txheej txheem ua raws cov qauv txawv teb chaws. Txawm li cas los xij, nyob rau hauv xyoo tsis ntev los no, Suav tau ua rau kev siv tshuab Aerospace tshiab, tab sis tseem yuav tau ntsib qhov sib txawv nrog qib kev nce qib hauv ntiaj teb.
I. Titanium Alloy: Tus "Universal Hlau" hauv Kev Ua Teb Aviation.
Titanium alloy tau siv dav hauv kev teb ib qho chaw vim nws lub ntiajteb txawj qis thiab muaj zog tshwj xeeb. Nyob rau hauv xyoo tsis ntev los no, titanium alloy tsis tau muaj npe nrov nyob rau hauv kev ua lag luam ntawm kev ua tub rog xws li kev lag luam chemical, metallurgy, kev kho mob thiab kev ua si.
Thoob ntiaj teb, tshaj titanium alloys xws li high-kub titanium alloys thiab nplaim taws-retaircy allots tau siv dav hauv cov dav hlau qauv thiab lub cav sib xyaw. Piv txwv li, qhov kev kub siab titanium alloys ti {4}} s thiab bt36 los ntawm Tebchaws Russia, tau pom zoo heev hauv kev ua haujlwm siab.
Nyob rau hauv Suav teb, tus neeg tsim nyog tau tsim ti -60 alloy yog ib tug 600 degree siab-kub titabital stability thiab high-kub creep muaj zog. Tsis tas li ntawd, High-lub zog Txheej Txheem Titanium Alloys tsim los ntawm Tuam Tshoj thaum pib ntawm-beta titanium alloy Ti-B20, tau mus txog qib siab ntawm lub zog tensile. Tuam Tshoj tau kuj tau ua kom zoo tshaj plaws hauv cov nplaim taws titanium alloys, xws li tus nplaim taws thiab muaj cov khoom siv hluav taws xob zoo thiab tau tsim mus rau ib nrab kev lag luam nplai.
Txawm li cas los xij, txawm hais tias cov kev ua tiav no, Tuam Tshoj Trentane Alloy Kev Lag Luam tseem ntsib yooj yim qee qhov kev cov nyom. Piv txwv li, High-xaus titanium alloy cov khoom tseem feem ntau yog imitated, nrog qib qis ntawm cov ntaub ntawv kev txhim kho thiab ntau yam ntawm cov ntawv thov. Nyob rau tib lub sijhawm, cov xim hlau tsis ruaj khov yog tsis ruaj khov, nrog tsawg dua ntau yam thiab cov kev tshawb fawb tsis tiav, thiab cov kev tshawb fawb ntawm kev txhawb nqa kev txhawb nqa tau qeeb.
Thib ob, high-kub alloys: cov ntaub ntawv tseem ceeb rau cov tshuab hluav taws xob
Kev kub-alllo yog hom tshwj xeeb alloy uas tuaj yeem ua haujlwm ntawm thaj chaw muaj zog tshaj li 600 degrees hauv thaj chaw kub lub zog xws li lub cav. Raws li cov txheej txheem cov txheej txheem sib txawv, npib tsib xee-reflection high-kub alloys hauv qhov kev kub siab, cov khoom siv nyiaj ntau rau 80%.
Kev kub nyhiab alloys tau siv dav hauv Aero-tshuab, feem ntau yog rau kev tsim khoom ntawm plaub qhov kev sib xyaw ua ke, cov lus qhia, tshuab luam yeeb thiab tshuab luam yeeb. Cov theem kev ua tau zoo ntawm cov khoom siv no ncaj qha txiav txim siab qhov kev ua tau zoo tag nrho ntawm lub cav. Yog li ntawd, kev tshawb nrhiav thiab kev txhim kho thiab kev siv ntawm cov kev kub siab yog qhov tseem ceeb rau kev txhim kho kev ua haujlwm ntawm Aero-tshuab.
Hauv Suav teb, lub high-kub alloy kev lag luam tseem nyob hauv lub sijhawm loj hlob, thiab kev lag luam saw kev lag luam muaj qhov dav dav rau kev txhim kho yav tom ntej. Txawm li cas los xij, piv nrog Tebchaws Asmeskas thiab lwm lub tebchaws tsim khoom, tus naj npawb ntawm Suav high-high-alloy alloy ntau lawm tsim kev lag luam thiab cov qib kev tsim khoom tseem yuav tau txhim kho.
Txhawm rau muab cov ntsiab lus, Tuam Tshoj tau ua rau kev nce qib hauv kev ua teb cov ntaub ntawv siv thev naus laus zis, tab sis tseem yuav ntsib ntau yam kev cov nyom. Txhawm rau txhim kho kev ua tau zoo ntawm aviation, Suav yuav tsum txhawb nqa cov khoom siv R & Devers thiab txhawb nqa cov ntaub ntawv tshiab xws li AnnaS thiab kev kub ntxhov. Nyob rau tib lub sijhawm, nws kuj yuav tsum muaj zog sib pauv thiab kev koom tes nrog qib kev nce qib hauv ntiaj teb ua ke txhawb kev nce qib ntawm ntiaj teb aviation cov khoom siv tshuab.
