Qhov ceev ntawm lub dav hlau niaj hnub tau mus txog ntau dua 2.7 npaug ntawm lub suab nrawm.Xws li lub davhlau nrawm nrawm yuav ua rau lub dav hlau rub tawm tsam huab cua thiab tsim kom muaj cua sov ntau.Thaum lub davhlau ceev nce mus txog 2.2 npaug ntawm lub suab nrawm, aluminium alloy tsis tuaj yeem sawv ntsug.Kub kub resistant titanium alloy yuav tsum tau siv.Tom ntej no, Kws Tshaj Lij los ntawm RSM Technology Department yuav qhia qhov laj thawj yog vim li cas titanium alloy lub hom phiaj tseem ceeb hauv kev lag luam aviation!
Thaum lub thrust rau qhov hnyav piv ntawm aeroengine yog nce los ntawm 4 mus rau 6 mus rau 8 mus rau 10, thiab lub compressor qhov hluav taws xob qhov hluav taws xob kub yog sib npaug los ntawm 200 mus rau 300 ℃ mus rau 500 mus rau 600 ℃, lub compressor tsis tshua muaj siab compressor disk thiab hniav Ameslikas tsim los ntawm aluminium yuav tsum tau hloov nrog titanium alloy.
Nyob rau hauv xyoo tas los no, cov kws tshawb fawb tau ua tiav tshiab hauv kev tshawb fawb ntawm cov khoom ntawm titanium alloys.Tus thawj titanium alloy tsim los ntawm titanium, aluminium thiab vanadium muaj qhov kub thiab txias ua haujlwm ntawm 550 ℃ ~ 600 ℃, thaum lub tshuab tshiab tsim aluminium titanate (TiAl) alloy muaj qhov siab tshaj plaws ua haujlwm kub ntawm 1040 ℃.
Siv titanium alloy es tsis txhob stainless hlau los ua kom muaj zog compressor disks thiab cov hniav tuaj yeem txo qhov hnyav ntawm cov qauv.Roj tuaj yeem txuag tau los ntawm 4% rau txhua 10% txo qis hauv dav hlau hnyav.Rau lub foob pob hluav taws, txhua 1kg txo tuaj yeem nce qhov deb ntawm 15 km.
Nws tuaj yeem pom tias titanium alloy ua cov ntaub ntawv yuav raug siv ntau thiab ntau dua hauv aviation, thiab cov tuam txhab loj titanium alloy yuav tsum mob siab rau lawv tus kheej rau kev tshawb fawb thiab kev tsim kho thiab tsim cov khoom siv high-end titanium alloys los xyuas kom meej qhov chaw hauv titanium alloy lag luam.
