Cov khoom siv muaj yog haum rau 3D luam ntawv ntawm high- Lub zog allloy steel?

, Lub peev xwm ntawm kev siab siab - Lub zog alloyoL hlau los ua 3D luam tawm: kev sib xyaw ntawm cov khoom muaj txiaj ntsig thiab cov txiaj ntsig cov txiaj ntsig
Cov 3D luam tawm siv ntawm high- lub zog alloy) tshwm sim los ntawm lawv qhov txawv manloy metallurgical thiab syergistic txuas ntxiv tsim kev lag luam:
Txoj Kev Tswj Xyuas Ntawm Microstructure
3D luam ntawv tus "txheej los ntawm txheej melting ceev solidification" yuav pab tswj qhov loj thiab kev coj ua ntawm cov hlau nplaum. Piv txwv li, lub laser mel me me me me melting (slm) cov txheej txheem yuav ua rau cov nplej hauv 18NI300 martensitic hnub nyoog me me rau qib micrometre. Qhov no ua rau cov paib muaj zog 30% muaj zog dua li cov kev tsis pom zoo. Lub koom haum ntawm cov hlau ntawm Suav Academy ntawm kev tswj hwm cov txheej txheem kev kho cua sov zoo heev tuaj yeem nres cov txheej txheem cua sov zoo heev ntau dua 50% ntau tiv taus kev qaug zog. Hom no tseem tuaj yeem siv los txhim kho cov qauv nplej ntawm high- lub zog alloyoy.
Lub peev xwm los ua kom muaj kev nyuaj
Cov neeg feem ntau ua haujlwm siab siab - Lub zog alloy hlau los ua qhov chaw hnyav, cov pob hluav taws xob hnyav rau cov ntoo hluav taws xob thiab siab rau cov ntoo hluav taws xob nuclear. Yav dhau los, kev tsim khoom thiab vuam yuav tsum tau ua nyias. Nrog 3D luam tawm, tab sis, koj tuaj yeem ua kom cov duab nyols zoo li sab hauv thiab ua kom haum txias raws txhua lub sijhawm. NASA ntiav Inconel 718, ib npib tsib xee}}} reflect alloy nrog 18% molybdenum, los ua pob zeb cav nozzles nrog 3D luam ntawv. Cov Cheebtsam nyob hauv lub suab nrov ntawm cov kub ntawm 2000℃vim tias mus rau permeable txias channel tsim. Qhov no tsis tuaj yeem ua tau nrog uake uake.
Siv cov ntaub ntawv thiab cov nqi qis dua
Siv cov tsoos forging technology, tsuas yog 50% mus rau 70% ntawm cov khoom siv tau siv, tab sis 3D luam tuaj yeem siv ntau dua 90%. Piv txwv li, ARU tau siv 3D luam tawm los ua cov hlau uas tsis muaj pwm rau tsheb. Qhov no tau txiav qhov hnyav ntawm txhua feem ntawm 75%, tus nqi ntawm cov hlau siv los ntawm 30%, thiab kev ua haujlwm ntawm kev tsim khoom los ntawm 10 zaug. Rau siab - Lub zog Alloy Hlau Zoo li H13 pab rau ib phaus, siv cov khoom siv tsawg dua txhais tau tias cov nqi loj.
2, Cov Ntaub Ntawv Siv Tau Siv: Kev siv kev siv 3D luam kom muaj siab kom siab- lub zog alloyoy
1. Aerospace: ib qho kev sib tsoo ntawm lub teeb yuag thiab siab - lub zog dav dav cav. Platinum Lite ua lub siab - kub ecoy rau kev siv cov kev xav tau rau cov kev xav tau rau kev siv kub ntawm 1000 degree.
Qhov chaw ntawm lub nkoj huab cua tus qauv: Xib fwb zhang Haih pab pawg tau tsim "kev sib xyaw, Forging" 3D luam ntawv tshuab. Cov thev naus laus zis tau siab heev - Lub zog aluminium alloy qhov uas yog 500 cm ntev, suav nrog cov qauv tsaws ntawm C919 lub dav hlau. Cov thev naus laus zis no ua cov duab casting, Forging, thiab cov txheej txheem milling tib lub sijhawm. Qhov no ua rau seem ob zaug kom muaj zog tiv thaiv kev qaug zog thiab txiav lub sijhawm tsim khoom los ntawm 60% piv rau cov qauv ib txwm muaj.
2. Lub zog thiab tshuaj lom neeg kev lag luam: kev lav ntawm corrosion tsis kam thiab ruaj khov ntawm qhov kub siab
Cov cuab yeej siv hluav taws xob nuclear: cov cuab yeej sib koom ua haujlwm ua haujlwm nplaum nplaum kom 3D sau cov hlau hluav taws xob hlau (xws li sa}} alloy Cov Cheebtsam tuaj yeem tiv taus 360℃thiab 17.2 mpa tsis corroding, uas ua tiav ittm 923 cov qauv. Qhov no txhais tau tias cov khoom siv uas raug rau peb zaug tau ntev dua.
Roj thiab roj Extraction: Schlumberger ua haujlwm Electron Beaster Melting (EBM) Technology to 3D}}}}} hiav txwv drilling platform. Cov txuas yog ua los ntawm 4140 tsawg {{4 4}} moyoy mo} mohy bu discenities, uas yog roj thiab roj kev loj hlob hauv Arctic lub voj voog xav tau.
3. Automotive manufacturing: Txoj kev tshiab los ua tej yam lub teeb yuag thiab muaj txiaj ntsig
Hluav Taws Xob Tsheb Roj Teeb: Volvo Siv Cov Tshuaj Txias Txias Txau Hlau Hlau 3D Tshuab Luam Ntawv los ua cov roj teeb pob nkhaus. Lawv siv H13 cuab yeej hlau (uas muaj 5% CR thiab 1.5% v) thiab cov qauv kev tsim qauv biomimetic Latsis. Qhov cuam tshuam lub zog lub zog nqus tau muaj peev xwm tau nce, thiab qhov hnyav tau txiav los ntawm 35%. Qhov no ua tau raws li kev sib cav sib tsoo kev nyab xeeb rau hluav taws xob tsheb.
Cav nrog kev ua haujlwm siab: lub valve rooj rings ntawm bmw m ing}}}-series cav yog ua los ntawm titanium alloy (ti}}}}} 6v) uas tau yog 3D luam tawm. Lub rings ces coated nrog npib tsib xee-raws tungsten carbide los ntawm saum npoo laser cladding. Piv rau cov qauv hmoov metallurgy, feem yog plaub zaug tiv thaiv kev hnav ntawm 900℃thiab yim yim caum.
3, teeb meem cov kev daws teeb meem: teeb meem tseem ceeb uas yuav tsum tau daws ua ntej cov chaw ua haujlwm tuaj yeem dhau los ua cov Hoobkas
3D luam tawm ntawm high- Lub zog alloy hlau muaj ntau yam kev cog lus, tab sis tseem muaj peb qhov teeb meem tseem ceeb uas yuav tsum tau daws ua ntej nws tuaj yeem siv rau ntawm qhov loj loj:
Kev Tswj Cov Nqi thiab Luam Ntawv Npaum
Nws tseem siv sijhawm 6 txog 8 teev los luam ib qho loj, zoo li lub plhaub cav. Cov nqi ntawm cov khoom siv nyiaj rho tawm thiab cov hmoov ua tus nqi tsim khoom 3 txog 5 zaug siab dua cov hau kev dhau los. Lub Platinum Blt - s800 s800- Laser taub hau kev thev naus laus zis tuaj yeem txo tus nqi raw los ntawm 40%.
Tswj kev ntxhov siab thiab deformation
Thaum siab - Lub zog Alloy Steel txias nrawm nrawm, nws tuaj yeem ua rau muaj kev ntxhov siab, uas tuaj yeem ua rau seem los yog tawg. Addup thiab ECM pab pawg tau ua haujlwm ua ke los tsim cov kev kho cua sov uas muaj kev ntxhov siab rau hauv 0.1mm los ntawm kev kho mob stadaging rau 2 teev {
Nce tus lej thiab hom ntaub ntawv
Right now, there are only a little over ten mature 3D-printed high-strength alloy steels. These steels are hard to use in really harsh conditions, such very high temperatures (>1200 degree) thiab corrosion tseem ceeb (raws li nyob rau hauv damp H2S ib puag ncig). Kev tsim cov khoom siv hluav taws xob tshiab cov ntaub ntawv, xws li Tic - 18ni300, yog thawb cov kev txwv ntawm cov ntaub ntawv. Nws tuaj yeem tau txais nyuaj li HRC 65, uas yog 50% nyuaj dua li cov hlau ntshiab. Qhov no ua rau nws zoo rau kev ua ntu uas yuav tsis hnav tawm ntawm lub platform sib sib zog nqus.
