Vim li cas cov titanium alloys tseem ceeb rau kev ua teb?
Aug 12, 2025
Titanium thiab aviation muaj kev sib cog lus inextricable. Xyoo 1953, titanium tau siv thawj zaug hauv lub cav nacelles thiab firewalls ntawm DC {2} Toplas Aircrace, khij qhov pib ntawm titanium txoj kev siv titanium. Txij thaum ntawd los, titanium tau siv rau hauv kev tsav dav hlau rau ib nrab xyoo. Titanium qhov kev siv dav dav siv hauv kev ua teb yog vim nws cov khoom muaj txiaj ntsig ntau rau cov ntawv thov cov dav hlau. Niaj hnub no, peb yuav tham txog vim li cas titanium alloys yog qhov tseem ceeb rau kev ua pa.
I. Taw qhia rau Titanium
Xyoo 1948, Dutront hauv Tebchaws Meskas tau pib ua haujlwm tons ntawm titanium daim txhuam cev siv cov txheej txheem magnesium Titanium alloys tau siv dav hauv ntau thaj teb vim lawv lub zog siab, zoo nkauj corrosion, thiab kub ua kom tsis kam.
Titanium yog cuaj feem ntau ntau cov hlau nyob hauv lub ntiaj teb crust, deb tshaj li ntau hlau xws li tooj liab, zinc, thiab tin. Titanium yog dav tam sim no hauv ntau lub pob zeb, tshwj xeeb yog cov xuab zeb thiab av nplaum. Ii. Titanium cov yam ntxwv
Lub zog siab: 1.3 lub sij hawm uas ntawm txhuas alloys, 1.6 lub sij hawm uas ntawm magnesium alloys, thiab 3.5 lub sij hawm uas ntawm stainless hlau, nws yog cov khoom siv muaj zog tshaj.
Siab kub ua zog: kev khiav haujlwm kub yog ntau pua degrees siab dua li cov neeg ua haujlwm ntev, tso cai ntev}} kev ua haujlwm ntev ntawm qhov kub ntawm 450-500 degree.
Zoo heev corrosion: resistant rau cov kua qaub, alkalis, thiab atmospheric corrosion, nws yog tshwj xeeb tiv thaiv pitting thiab kev ntxhov siab corrosion.
Zoo heev qis - kub kev ua tau zoo: Ta7, ib titanium alloy nrog cov ntsiab lus tsis tshua muaj me ntsis ntawm -253 degree.
Siab tshuaj lom neeg: heev nquag ntawm kev kub siab, nws tau yooj yim reacts nrog hydrogenities xws li oxygen thiab oxygen nyob rau saum huab cua, sib sau ib txheej tawv tawv.
Tsawg thermal conductivity thiab tsawg elastic modulus: nws thermal conductivity yog kwv yees li 1/4 uas ntawm cov hlau, thiab 1/14 uas yog txhuas. Lub thermal conductivity ntawm ntau titanium alloys yog kwv yees li 50% qis dua li ntawm titanium. Elastic modulus ntawm titanium alloys yog kwv yees li 1/2 tus hlau. III. Kev faib tawm thiab kev siv ntawm titanium alloys
Titanium alloys tuaj yeem raug faib ua ke rau hauv tshav kub {{{{{{{{{{{{{{{{- kub Alloys, thiab tshwj xeeb - lub hom phiaj alloys (xws li titanium {}}} {8} {8} {8} {}}}}}}}}}}}}}}}}}}}}}}}}}}}} tus kheej lub cim xeeb alloys).
Txawm hais tias titanium thiab nws cov alloys muaj keeb kwm luv luv ntawm daim ntawv thov, lawv tau txais ntau cov kev tsim qauv vim lawv cov khoom tshwj xeeb. Thawj ntawm cov no yog "chaw hlau." Nws lub teeb yuag, muaj lub zog siab, thiab siab- kub ua rau nws cov dav hlau tsim nyog ua rau kev tsim cov dav hlau thiab ntau lub nkoj. Tam sim no, kwv yees li peb {{4 4}} artters ntawm lub titanium thiab titanium alloys tsim thoob ntiaj teb siv hauv Aerospace kev lag luam. Ntau cov khoom sib piv yav dhau los ua los ntawm txhuas alloys tau hloov pauv mus rau titanium alloys.
IV. Aerospace cov ntawv thov ntawm titanium alloys
Titanium alloys feem ntau yog siv nyob rau hauv dav hlau thiab lub cav tsim, compressor disks thiab cov txheej txheem sib xyaw ua ke xws li cov teeb meem dav hlau thiab bulkheads. Spacecraft feem ntau siv titanium alloys 'lub zog muaj zog, thiab qis} cov roj tso tsheb hlau, cov hlua roj av, thav duab, thiab cov pob zeb ua pob zeb. Artificial Satellites, Lunar Modules, Manned Tshav Ntuj, thiab qhov chaw Shuttle Tag Nrho Siv Cov Ntawv Welanium Alloy.
Xyoo 1950, Tebchaws Asmeskas siv titanium alloy ntawm f- bearing {46} Pib thaum xyoo 1960, kev siv titanium alloy hloov pauv ntawm lub tsev fuselage, ib nrab fuselage xws li bulkheads, teeb liab, thiab flap ntsia. Pib thaum xyoo 1970, neeg thoob tebchaws pib siv titanium alloy ntau yam. Piv txwv li, Boeing 747 tus neeg caij dav hlau siv dhau 3,640 kilo ntawm titanium, suav nyiaj rau 28% ntawm lub dav hlau hnyav. Nrog kev nce qib ntawm kev ua thev naus laus zis, titanium alloys kuj tau siv ntau hauv Rockets, Satellites, thiab Huab Cua, thiab Huab Cua.
Qhov ntau tshaj lub dav hlau, cov ntau titanium yog siv. Teb Chaws Asmeskas F- 14A fighter siv titanium alloy rau kwv yees li 25% ntawm nws qhov hnyav; F-15A FIVER USES 25.8%; US-theem plaub FOLVIDE siv 400% titanium, thiab nws lub dav hlau uas muaj 39% yog vim li cas rau kev siv titanium ntau tshaj plaws hauv aviation nyob rau hauv aviation
Niaj hnub nimno dav hlau tau mus txog qhov nrawm tshaj plaws ntawm ntau dua 2.7 zaug lub suab nrawm. Xws li SuperSonic ya dav dav dav heev vim kev sib txhuam ntawm lub dav hlau thiab huab cua. Ntawm qhov nrawm tshaj 2.2 lub sij hawm ceev ntawm lub suab, alloys tsis tuaj yeem tiv taus qhov no. High - kub -} tiv taus titanium alloys yog qhov tseem ceeb.
Raws li lub thrust - -}}}}}}}}}}}} Txoj kev siv hluav taws xob tau nce los ntawm txhuas yuav tsum tau hloov nrog cov alloys alloys.
Xyoo tsis ntev los no, cov kws tshawb fawb tau ua tiav kev nce qib txuas ntxiv hauv kev tshawb fawb ntawm cov khoom ntawm titanium alloys. Qhov kev ua haujlwm siab tshaj plaws ntawm titanium alloys, xub thawj tsim ntawm titanium, yog 550-600 tsim cov khoom siv tam sim no tau nce nws qhov kev ua haujlwm siab tshaj plaws txog 1040 degree.
Siv cov titanium alloys tsis txhob siv cov hlau stainless rau high-} kub compressor disks thiab tuaj yeem txo cov teeb meem hnyav. Txhua 10% qhov hnyav txo qis hauv cov dav hlau cawm 4% hauv roj. Rau lub foob pob ua pob zeb, txhua 1KG qhov hnyav txo qis nws ntau yam los ntawm 15km.
VI. Kev tsom xam ntawm titanium alloy machining cov yam ntxwv
Ua ntej, titanium alloy muaj qhov tsawg thermal conductivity, tsuas yog 1/13 hais tias ntawm txhuas, thiab 1/25 uas tooj liab. Qhov cua sov no tsis txaus ntseeg los ntawm kev txiav cov kab kev txiav txim siab thermal sib npaug, ua rau cov cua sov tsis zoo thiab txias thaum lub sijhawm txiav. Qhov no yooj yim ua rau muaj qhov kub nyob hauv cov chaw txiav, ua rau muaj kev pom zoo thiab lub caij sov nyob hauv ib feem
Thib ob, Titanium Alloy Tsawg Thermal Bermal kev cob haum txiav kom tshav kub rau qhov cuab yeej me me nyob ze ntawm cov cuab yeej txiav, ua rau nws nyuaj rau dissipate. Qhov no nce kev sib txhuam ntawm lub sua taws ntsej muag, cuam tshuam chip tshem tawm thiab cua sov dissipation, nrawm dua kev hnav. Thaum kawg, titanium alloy yog siv tshuaj, thiab thaum ua tiav cov khoom siv kub, uas nws tau yooj yim, uas tuaj yeem ua rau cov cuab yeej sticking, hlawv, thiab lub cuab yeej tawg.
Lub tuam txhab khav ua cov khoom lag luam hauv tsev titanium ua ntau lawm, nrog rau:
