Vim li cas titanium alloys dav siv nyob rau hauv aircraft cav?
Cov tshuab dav hlau ua haujlwm nyob rau hauv cov xwm txheej xav tau heev, suav nrog kev sib hloov ceev, qhov kub siab, thiab cov huab cua tsis yooj yim. Cov xwm txheej no tso cai nruj rau kev ua haujlwm ntawm cov khoom siv. Cov ntaub ntawv yuav tsum muab lub zog siab thiab cov qauv kev ruaj ntseg thaum tseem ua kom tag nrho qhov hnyav kom tsawg li sai tau los txhim kho lub cav efficiency thiab kev ua haujlwm ntawm lub dav hlau. Titanium alloys ua lub luag haujlwm tseem ceeb hauv kev tsim dav hlau dav hlau vim lawv cov khoom zoo heev. Lawv tau dav siv nyob rau hauv compressor hniav, cav casings, thiab ntau yam structural Cheebtsam, muab ib tug txhim khu kev qha cov ntaub ntawv lub hauv paus rau ntev - lub sij hawm ruaj khov cav.
Siab zog - rau - Qhov hnyav piv
Ntau yam khoom siv hauv lub tshuab dav hlau ua haujlwm ntawm kev sib hloov ceev thiab yuav tsum tiv taus kev ntxhov siab tseem ceeb. Nyob rau tib lub sijhawm, hnyav hnyav yuav tsum zam. Titanium alloys muaj lub zog siab - rau - qhov hnyav piv, tso cai rau cov qauv muaj zog thaum txo qhov hnyav tag nrho.
- Lub zog muaj zog los tiv taus cov neeg kho tshuab loj
- Tsawg ntom pab txo cov khoom hnyav
- Txhim kho tag nrho lub cav efficiency
- Txhawb optimized engine structural tsim
Cov yam ntxwv no ua rau cov titanium alloys muaj txiaj ntsig zoo rau cov khoom siv cav.
Zoo Siab -Kev Ua Haujlwm Kub
Cov tshuab dav hlau tsim hluav taws xob tseem ceeb thaum lub sijhawm ua haujlwm, thiab qee cov khoom siv yuav tsum ua haujlwm tsis tu ncua hauv qhov kub thiab txias. Titanium alloys tuaj yeem tswj tau cov khoom siv kho tshuab zoo hauv qhov nruab nrab siab - qhov kub thiab txias.
- Khaws lub zog ruaj khov ntawm qhov kub siab
- Zoo tiv thaiv thermal qaug zog
- Tsis tshua muaj deformation tshwm sim los ntawm qhov kub thiab txias
- Haum rau cov khoom siv nyob rau hauv qhov kub siab dua ntawm lub cav
Qhov thermal stability no tso cai rau titanium alloys kom tau raws li qhov xav tau kev ua haujlwm ntawm cov tshuab dav hlau.
Zoo heev Corrosion Resistance
Thaum lub sijhawm ua haujlwm, cov tshuab dav hlau raug rau huab cua ntub, combustion los ntawm -cov khoom, thiab ntau yam roj gases, txhua yam uas yuav ua rau cov khoom siv corrosion. Titanium alloys pom muaj zog corrosion kuj nyob rau hauv cov cheeb tsam no.
- Ib txheej oxide ruaj khov ua rau ntawm qhov chaw
- Ua kom muaj tshuaj lom neeg ruaj khov hauv qhov chaw sib txawv
- Txo kev puas tsuaj los ntawm corrosion
- Pab kom ntev kev pab cuam lub neej ntawm lub cav Cheebtsam
Cov khoom no pab txhawb kev txhim kho lub cev muaj zog.
Zoo Fatigue Resistance
Cov tshuab dav hlau ua haujlwm rau lub sijhawm ntev thiab muaj kev hloov pauv ntau zaus. Yog tias cov khoom muaj kev qaug zog tsis zoo, cov kab nrib pleb thiab kev ua haujlwm tsis zoo yuav tshwm sim. Titanium alloys ua tau zoo nyob rau hauv cyclic loading tej yam kev mob.
- Muaj peev xwm tiv taus qhov kev ntxhov siab rov qab rau lub sijhawm ntev
- Txo qhov kev pheej hmoo ntawm kev tawg ntawm cov qauv
- Extens lub neej kev pab cuam ntawm cov khoom tseem ceeb
- Txhawb nqa ntev - lub sij hawm ruaj khov lub cav ua haujlwm
Raws li aviation technology txuas ntxiv mus, cov kev ua tau zoo ntawm cov khoom siv cav tau dhau los ua qhov xav tau. Titanium alloys muab kev sib xyaw ua ke ntawm lub zog siab, tiv thaiv tshav kub, thiab kev ruaj ntseg, ua rau lawv siv dav hauv ntau yam tseem ceeb ntawm cov tshuab dav hlau niaj hnub.
