Aluminium alloy thiab titanium alloy, vim lawv lub zog qis dua thiab kev tsim kho hauv tsev, puas yog siv tshuab av, tshwj xeeb yog hauv kev lag luam aviation? cov ntaub ntawv tseem ceeb hauv kev lag luam aviation.
Titanium thiab txhuas yog ob qho tib si lub teeb, tab sis muaj qhov sib txawv. Txawm hais tias titanium yog kwv yees li ob feem peb hnyav dua li txhuas los ntawm qhov hnyav, nws lub zog muaj zog txhais tau hais tias tsawg dua tuaj yeem siv los ua kom tiav lub zog xav tau. Titanium alloys tau siv dav hauv cov dav hlau dav hlau dav hlau thiab ntau lub dav hlau, thiab lawv lub zog thiab qhov ntom ntom tuaj yeem txo cov nqi roj. Qhov ntom ntawm aluminium alloy tsuas yog ib feem peb ntawm cov hlau, thiab nws yog cov khoom siv dav siv ntau tshaj plaws thiab cov khoom siv hauv tsheb loj tshaj plaws nyob rau theem no. Cov kev tshawb fawb tau pom tias aluminium alloy tuaj yeem siv txog li 540kg hauv lub tsheb, nyob rau hauv rooj plaub no lub tsheb yuav poob 40% ntawm nws qhov hnyav, thiab tag nrho-aluminium lub cev ntawm Audi, Toyota thiab lwm hom yog ib qho piv txwv zoo.
Txij li thaum ob qho khoom siv muaj lub zog siab thiab qhov ntom ntom, lwm qhov sib txawv yuav tsum tau txiav txim siab thaum txiav txim siab siv cov alloy.
Lub zog / qhov hnyav: Hauv qhov xwm txheej tseem ceeb, txhua gram ntawm ib feem suav, tab sis yog tias xav tau qhov muaj zog ntau dua, titanium yog qhov kev xaiv zoo tshaj. Qhov no yog vim li cas titanium alloys yog siv nyob rau hauv kev tsim cov khoom kho mob / cog, complex satellite assemblies, fixtures thiab stents.
Tus nqi: Aluminium yog cov hlau zoo tshaj plaws rau machining lossis 3D luam ntawv; Txawm hais tias tus nqi ntawm titanium yog siab, nws tseem tuaj yeem txhawb nqa tus nqi dhia. Kev txuag roj ntawm cov khoom hnyav rau lub dav hlau lossis lub dav hlau yuav ua rau muaj txiaj ntsig zoo, thaum lub sijhawm ua haujlwm ntawm titanium qhov chaw ntev dua.
Thermal zog: Aluminium alloy muaj thermal conductivity thiab feem ntau siv los ua radiators; Rau cov kev siv kub kub, qhov siab melting point ntawm titanium ua rau nws tsim nyog, thiab aircraft xyaw muaj ib tug loj tus naj npawb ntawm titanium alloy Cheebtsam.
Corrosion tsis kam: Aluminium thiab titanium muaj kev tiv thaiv corrosion zoo heev.
Titanium qhov corrosion kuj thiab tsis tshua muaj reactivity ua rau nws yog biocompatible hlau thiab nws yog dav siv nyob rau hauv kev kho mob (xws li cov cuab yeej phais). Ti64 kuj tseem tiv taus cov ntsev ib puag ncig thiab feem ntau siv hauv Marine daim ntaub ntawv.
Aluminium thiab titanium alloys muaj ntau heev hauv kev siv aerospace. Titanium alloy muaj lub zog siab thiab tsis tshua muaj zog (tsuas yog hais txog cov hlau), thiab lub zog (muaj zog dua li lwm cov khoom siv ua kom muaj zog, zoo nkauj thiab lub teeb hnyav. Cov khoom siv dav hlau dav hlau, pob txha, tawv nqaij, fasteners thiab tsaws iav tuaj yeem ua los ntawm titanium alloy. Nws tau pom tias aluminium alloy tsim nyog rau kev ua haujlwm hauv ib puag ncig qis dua 200 degree C, thiab cov khoom siv txhuas siv nyob rau hauv lub fuselage ntawm Airbus A380 nyiaj ntau dua 1/3, thiab C919 kuj siv ntau cov pa ua haujlwm siab. aluminium alloy cov ntaub ntawv. Lub dav hlau daim tawv nqaij, spacer thav duab, tis tav, thiab lwm yam, tuaj yeem ua los ntawm aluminium alloy.
