Pab Cov Teb Chaws Loj Tshaj Tawm - Kev Tshawb Fawb titanium Alloy
Chongqing Science thiab Technology Innovation Center ntawm Northwestern Polytechnical University yog nyob rau ntawm ntug dej ntawm Mingyue Lake thiab tau raug nthuav tawm thaum lub Plaub Hlis 2021. Tam sim no, pab pawg tshawb fawb txog kev tshawb fawb txog ze li ntawm 300 tus neeg tau tso tseg los ua kev tshawb fawb txog kev tshawb fawb nyob ib puag ncig titanium alloy cov ntaub ntawv rau kev siv aerospace. .
Xib fwb Li Jinshan concurrently ua tus thawj tswj hwm ntawm Lub Tsev Kawm Ntawv ntawm Cov Khoom Siv Science thiab Engineering ntawm Northwestern Polytechnical University thiab tus thawj kws tshawb fawb thiab tus thawj coj ntawm Chongqing Science thiab Technology Innovation Center ntawm Northwestern Polytechnical University. Nws feem ntau yuav tsum tau khiav thiab tawm tsam ob qhov kawg, thiab nws tuaj yeem hais tau tias nws lub sijhawm puv heev. Raws li kuv lub teb chaws tus kws tshaj lij hauv kev ua haujlwm ntawm titanium alloy cov ntaub ntawv, nws qhov kev tshawb fawb kev tshawb fawb yog ze rau kuv lub teb chaws "lub zog loj thiab riam phom tseem ceeb".
Li Jinshan tau hais tias, piv txwv li, titanium alloy diaphragm no yog tsim rau cov foob pob hluav taws. Ntawm cov foob pob hluav taws, satellites lossis qee yam riam phom, yog cov roj hmab siv rau kev sib khi, qhov kub thiab txias tsis dhau thiab nws yooj yim rau hnub nyoog, yog li no hom elastomer yog tsim. Lub thawv hlau membrane muaj kev sib khi zoo dua. Lwm qhov piv txwv yog kauv rivets. Ib lub dav hlau tuaj yeem muaj kaum tawm txhiab tus kauv rivets, uas tuaj yeem suav txog ntau dua 5% ntawm tag nrho qhov hnyav ntawm lub dav hlau. Keeb kwm tsim los ntawm cov hlau alloy steel, qhov no tau hloov mus rau titanium kom txuag tau qhov hnyav.
Dab tsi yog qhov zoo ntawm titanium alloys piv nrog cov khoom siv tsoos? Cov ntawv thov tseem ceeb yog dab tsi?
Li Jinshan: Nws yog cov khoom siv nrog lub zog tshwj xeeb tshaj plaws thiab nruj nruj ntawm tag nrho 89 cov ntaub ntawv hlau. Yog li ntawd, nws tau yug los ua aerospace. Raws li qhov chaw hlau, nws muaj kev cia siab zoo hauv thaj chaw aerospace. Qhov thib ob, nws muaj peev xwm loj heev hauv thaj chaw aerospace. Nws yog corrosion-resistant, yog li titanium alloys kuj siv rau pipeline li qub ntawm nkoj. Ib hom thib peb ntawm titanium alloy yog tshwj xeeb tshaj yog biocompatible. Nws kuj yog siv los ua biomaterial thiab muaj ntau yam kev siv hauv tib neeg lub cev. Txawm li cas los xij, qhov tsis zoo tshaj plaws ntawm titanium alloy yog tias nws muaj zog, cov txheej txheem tsim khoom yog qhov nyuaj heev, thiab nws yuav tsum muaj cov cuab yeej siv siab thiab thev naus laus zis.
Tam sim no, peb pab neeg muaj peev xwm ua tau li cas hauv titanium alloy manufacturing thiab R&D hauv tsev thiab txawv teb chaws?
Li Jinshan: Peb pab pawg tshawb fawb tshawb fawb hauv Tsev Kawm Ntawv ntawm Cov Khoom Siv, Northwestern Polytechnical University, tau nyob rau hauv kev tshawb fawb thiab ua ntej ntawm lub teb chaws txij li thaum siv titanium alloys hauv kuv lub teb chaws.
Koj xav tias qhov tseem ceeb ntawm peb cov kev siv thev naus laus zis hauv cheeb tsam no yog dab tsi?
Li Jinshan: Ua ntej 2000, kuv lub teb chaws kev lag luam aerospace tau rov qab heev. Lub hauv paus yog qhov tsis muaj cov khoom siv siab heev. Yav dhau los, peb yuav tsum tau cia siab rau kev xa tawm txawv teb chaws los siv cov titanium alloys. Thaum lub sijhawm tseem ceeb, lawv yuav txiav tawm lossis tsis kam muab peb cov titanium alloys. Zoo, txij li xyoo 2000, nrog rau peb lub teb chaws kev nqis peev hauv kev lag luam tiv thaiv, tshwj xeeb tshaj yog nyob rau hauv cov khoom siv, peb tau ntsib kev loj hlob sai hauv kev lag luam titanium alloys. Lub sijhawm ntawd peb tsuas suav txog 1% ntawm lub ntiaj teb feem. Tom qab 20 xyoo ntawm txoj kev loj hlob, txoj kev loj hlob ntawm Tuam Tshoj, uas yog thawj nyob rau hauv lub ntiaj teb no thiab yog ib tug loj titanium tsim, tau enabled peb manufacturing kev lag luam, tshwj xeeb tshaj yog cov tub rog tsim kev lag luam, thiab cov khoom theem los tsim los ntawm leaps thiab ciam teb, vim hais tias tus nqi ntawm cov khoom. titanium siv tuaj yeem ntsuas qhov zoo ntawm titanium alloys. Lub cim tseem ceeb ntawm kev nce qib ntawm lub dav hlau.
Li Jinshan: Lub National Key Laboratory ntawm Solidification yog tsim los ntawm qee qhov tseem ceeb thiab tseem ceeb casting Cheebtsam ntawm titanium alloys lossis high-temperature alloys lossis aluminium alloys thiab magnesium alloys hauv kuv lub teb chaws cov khoom siv dav hlau loj. Nws xav tias muaj ntau lub teb chaws cov fwj tseem ceeb.
