Cov khoom siv thiab cov khoom siv hlau 3D tshuab luam ntawv tau mus txog 1 billion US dollars nyob rau hauv lub ntiaj teb no. Txawm hais tias piv nrog cov yas 3D luam ntawv, tus nqi tso tawm tsuas yog kwv yees li 10 feem pua, nws xav tias hlau 3D luam ntawv yuav ncav cuag qhov ntsuas ntawm 10 billion los ntawm qhov kawg ntawm 2022. Yog li, titanium alloy 3D tshuab luam ntawv zoo li cas txawv ntawm thaj chaw ntawm hlau 3D luam ntawv? Qhov xwm txheej ntawm nws txoj kev tshawb fawb yog dab tsi? Yuav ua li cas txog daim ntawv thov kev cia siab nyob rau hauv aerospace thiab lwm yam teb?
Kev tshawb fawb ntawm titanium alloy 3D tshuab luam ntawv
Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob sai ntawm titanium alloy ncaj qha kev tsim thev naus laus zis xws li laser xaiv melting (SLM) kev tsim khoom thiab electron beam selective melting (EBSM) manufacturing, titanium alloy 3D printing manufacturing technology rau customized functional parts tau dhau los ua neeg paub tab. Cov molding, txheej txheem, thiab cov cuab yeej ntawm customized haumxeeb qhov chaw ntawm cov ntaub ntawv tau los ua ib tug kev tshawb fawb hotspot.
Selective laser melting SLM hais txog irradiating titanium alloy hmoov nrog ib tug laser beam nyob rau hauv kev tiv thaiv ntawm argon los yog nitrogen gas. Titanium alloy hmoov melts thiab solidifies sai sai tom qab muaj lub zog tsim kom muaj laser, thiab cov qauv ntom ntom, thiab siab-precision Titanium alloy ua haujlwm. Nws yog feem ntau siv titanium alloy 3D luam ntawv txoj kev rau kev tshawb fawb thiab kev tsim khoom hauv tsev thiab txawv teb chaws.
Kev siv hauv aerospace thiab lwm yam kev lag luam
Nyob rau hauv cov nqe lus ntawm daim ntawv thov teb ntawm titanium alloy 3D tshuab luam ntawv, titanium alloy 3D luam ntawv tau tsim sai heev nyob rau hauv lub aerospace thiab kev kho mob teb nyob rau hauv xyoo tas los. Cov xwm txheej siv dav tshaj plaws yog tsom rau hauv cov khoom siv dav hlau siab, kev kho hniav, thiab tib neeg pob txha. Cov ntaub ntawv feem ntau yog biomaterials nrog zoo sib xws nrog tib neeg cov ntaub so ntswg, xws li titanium alloy thiab stainless hlau. Tsis ntev los no, pab pawg kws tshaj lij phais mob ntawm lub Tsev Kho Mob Tsev Kho Mob Tsev Kho Mob Tsev Kho Mob Tsev Kho Mob tau ua tiav 3D luam tawm titanium alloy sternum tav, thiab tus neeg raug mob hnav titanium alloy "armor" los kho lub thorax tshiab.
Kev tsim khoom ncaj qha ntawm titanium alloy qhov chaw tab tom txhim kho sai hauv kev lag luam 3D luam ntawv. Kev siv cov hmoov hlau hmoov SLM cov khoom siv ncaj qha luam tawm thiab tsim cov titanium alloy qhov chaw daws cov teeb meem muaj tswv yim ntawm cov khoom me me thiab kev hloov kho hauv aerospace thiab lwm yam kev lag luam vim tias nws tuaj yeem ua cov txheej txheem ib txwm ua rau cov txheej txheem nyuaj uas nyuaj lossis txawm tias ua tsis tau, yog li nws muaj qhov tsis sib xws. zoo nyob rau hauv ncaj qha luam ntawv ntau lawm qhov chaw.
Vim tias qhov chaw hauv aerospace, aviation, kev kho mob, thiab lwm yam kev lag luam xav tau "high-precision", "high-quality" thiab "ultra-precision" cov yam ntxwv, cov kev xav tau siab dua tau muab tso rau ntawm qhov zoo ntawm titanium alloy 3D luam ntawv hmoov. Qhov zoo ntawm titanium alloy additive manufacturing qhov chaw yog ze ze rau cov khoom ntawm hlau hmoov, nrog rau cov hmoov particle loj, sphericity, fluidity, bulk ntom, thiab lwm yam.
Raws li JR kev soj ntsuam ntawm kev ua lag luam thiab mus sij hawm ntev titanium alloy 3D printing manufacturing xyaum, peb tshwj xeeb tshaj yog siv ultra-fine TC4 titanium alloy hmoov rau 3D printing thiab molding raws li qhov tshwj xeeb xav tau kev pab ntawm cov neeg siv ntev. Material manufacturing teb.
Cov khoom siv zoo heev ntawm titanium alloy 3D luam tawm cov khoom tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm aero-engines, thiab lawv lub zog tshwj xeeb thiab lub teeb yuag muab kev txhawb nqa rau cov hniav hnyav; cov khoom tiav lawm muaj siab thermal stability thiab oxidation tsis kam, uas yuav ncua lub neej ntawm cov hniav thiab lub sij hawm soj ntsuam; Nyob rau tib lub sij hawm, lub sab hauv ntawm ib feem txais ib tug hollow qauv, uas muaj ib tug loj tsim qhov chaw thiab muaj peev xwm paub ntau haiv neeg cov duab kom tau raws li cov kev xav tau ntawm ntau yam scenarios.
Titanium alloy 3D luam ntawv yog cov khoom tsim qauv siv dav hauv kev lag luam aerospace thiab kev kho mob. Tom qab cov khoom tsim los ntawm kev xaiv laser melting (SLM) cov cuab yeej tsim khoom siv ntxiv, cov khoom siv microstructure ntawm cov khoom tau txais yog sib xws thiab ntom thiab muaj cov yam ntxwv ntawm kev sib zog sai. Lub zog tensile, lub zog tawm los, thiab elongation ntawm cov khoom luam tawm yog kwv yees li 6-7 feem pua , 6-10 feem pua , thiab 55-60 feem pua siab dua cov ntawm cov khoom forged, feem. Cov khoom luam tawm muaj qhov raug siab sab hauv qhov tseeb, muaj zog tshwj xeeb, thiab cov khoom siv hluav taws xob kub siab, yog li cov khoom muaj peev xwm thauj khoom zoo thiab muaj peev xwm muaj kev ntxhov siab, uas ua tau raws li cov kev cai ntawm kev nyab xeeb-tseem ceeb xws li aerospace.
Yog li ntawd, daim ntawv thov kev cia siab ntawm titanium alloy 3D tshuab luam ntawv hauv aerospace thiab lwm yam kev lag luam yuav ci ntsa iab heev!
