Titanium hlau fiber ntau yog qhov chaw tshiab hauv kev tsim cov khoom siv science. Tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam ntawm aircraft, petrochemical, lub teb chaws kev ruaj ntseg, thiab kev noj qab haus huv, cov kws tshawb fawb tau tsom ntau thiab ntau nyob rau hauv xyoo tas los no ntawm kev tsim thiab siv hlau fiber ntau.
Cov tshuaj fiber ntau ua los ntawm cov hlau hlau uas muaj qhov ntev-rau-inch piv yog hu ua hlau fiber. Nws tseem tuaj yeem nthuav dav nws cov kev siv ntau yam los ntawm kev siv fiber ntau, raws li kev xav tias nws tau txais txiaj ntsig zoo hauv cov khoom siv hlau nws tus kheej.
Titanium fiber ntau muaj cov txiaj ntsig zoo xws li kub tsis kam, tsis kub tsis kam, tiv thaiv corrosion, lub teeb yuag, thiab muaj peev xwm nqus tau lub zog zoo. Yog li ntawd, titanium fiber ntau thiab titanium fiber ntau ntxeem tau cov ntaub ntawv muaj ntau yam kev siv thiab muaj peev xwm tiv taus ib puag ncig hostile.
1. Cov khoom siv suab nrov
Thaum lub suab nthwv dej nkag mus rau hauv cov khoom nrog xoob thiab ntxeem tau cov qauv, ntawm ib sab, nws yuav ua kom khov tsis kam vim kev sib txhuam ntawm huab cua molecules, thiab ntawm qhov tod tes, nws yuav hloov lub suab lub zog rau hauv lub zog hluav taws xob los ntawm kev siv hluav taws xob, thiaj li ua tiav lub hom phiaj ntawm lub suab nqus. Cov khoom siv fiber ntau yog cov khoom siv suab nrov nrov heev. Qhov no yog vim muaj cov laj thawj hauv qab no: ntawm ib sab, nws muaj lub qhov sab hauv nrog ib qho los ntawm kev qhib uas tuaj yeem txhim kho qhov kev sib txhuam ntawm lub suab tsis muaj zog thiab huab cua molecules kom nce viscous resistance;
Ntxiv nrog rau cov khoom tseem ceeb ntawm cov khoom siv suab nrov, cov hlau fiber ntau muaj lub zog zoo, thermal conductivity, corrosion kuj, kub tsis kam, thiab nws kuj muaj qhov tshwj xeeb electromagnetic shielding peev xwm ntawm cov ntaub ntawv hlau, tso cai rau nws ua hauj lwm rau siab. kev siv kub thiab kub siab. Nws yog siv los ua cov khoom siv hauv acoustic rau high-pressure aeroengines, raws li cov khoom siv hauv qab dej tsis tshua muaj suab nrov, thiab lwm yam.
2. Cov khoom siv txhawb zog
Ib qho khoom siv engineering nkaus xwb txoj kev txhim kho kev ua tau zoo tsis tuaj yeem ua raws li cov kev xav tau ntawm kev ua haujlwm txuas ntxiv vim kev nce qib hauv kev tshawb fawb thiab thev naus laus zis. Yog li ntawd, cov ntaub ntawv sib xyaw ua ke hauv ib qho piv txwv thiab yam tam sim no tau dhau los ua qhov tseem ceeb ntawm kev tshawb fawb.
Vim nws qhov tshwj xeeb modulus, siab tshwj xeeb lub zog, siab kub lub zog, kub oxidation kuj, kub creep kuj, lub teeb yuag thiab lwm yam zoo. Txawm hais tias titanium aluminium alloy tau dhau los ua ib qho ntawm cov ntaub ntawv zoo tshaj plaws rau cov tiam tom ntej ntawm aero-engine Cheebtsam, nws yog nquag tawg thiab muaj zog tsawg. Qhov teeb meem ntawm chav tsev kub plasticity hnyav txwv kev siv titanium-aluminium alloy. Kev taw qhia ntawm titanium fiber ntau rau hauv titanium-aluminium alloy tuaj yeem tiv thaiv kev nthuav tawm thiab nthuav tawm ntawm cov kab nrib pleb hauv titanium-aluminium alloy matrix, thiab tuaj yeem txhim kho qhov tshwj xeeb lub zog thiab cov qauv tshwj xeeb ntawm cov matrix alloy, thiab tuaj yeem ua haujlwm intragranular thiab intergranular los ntawm absorbing deformation. . Deformation thiab toughening ntawm lub hauv paus alloy.
Titanium thiab titanium alloys yog cov khoom siv biomedical zoo heev vim muaj qhov zoo hauv qab no: (1) lub teeb yuag, ceev (20 degree)=4.5g/cm3, thiab txo lub nra ntawm tib neeg lub cev tom qab implantation. (2) Piv nrog rau lwm cov khoom cog, nws muaj qhov qis dua elastic modulus ze rau tib neeg cov pob txha, uas tuaj yeem txo qhov kev ntxhov siab tiv thaiv tib neeg cov pob txha mus rau txawv teb chaws cog. (3) Tsis yog-magnetic, tsis cuam tshuam los ntawm sab nraud electromagnetic teb, thiab lwm yam. (4) Non-toxic. (5) Raws li cov khoom siv hlau inert, nws muaj biocompatibility zoo nrog tib neeg cov pob txha, cov ntaub so ntswg ntawm tes, thiab ntshav, thiab tsis muaj kev fab tshuaj thiab tsis muaj kuab paug rau tib neeg. (6) Zoo mechanical compatibility.
Ntxiv rau qhov kev siv tau hais los saum no, titanium fiber ntau cov ntaub ntawv ntxeem tau kuj muaj lwm yam kev siv tshwj xeeb, xws li kev npaj cov khoom siv hluav taws xob zoo rau kev sib txuas ua haujlwm siab, pom kev tsom xam, electromagnetic shielding, thiab lwm yam kev lag luam los ntawm kev siv cov titanium fibers 'kub hloov. khoom.
Piv txwv li, cov ntaub ntawv titanium fiber ntau muaj ntau yam kev siv vim qhov zoo ntawm titanium hlau nws tus kheej thiab cov yam ntxwv ntawm cov ntaub ntawv fiber ntau, ua rau nws tuaj yeem siv rau qee qhov tshwj xeeb thiab hnyav, thiab yuav muaj peev xwm zoo rau yav tom ntej. . Kev tshawb fawb thiab kev loj hlob muaj peev xwm thiab muaj txiaj ntsig zoo.
