Dab tsi yog cov nquag siv hlau 3D luam tawm cov ntaub ntawv hauv kev lag luam?

1. Stainless Hlau: Qhov sib npaug zoo tshaj plaws ntawm kev tiv thaiv kom xeb thiab pheej yig
Stainless hlau yog cov khoom siv ua haujlwm tshaj plaws rau cov khoom lag luam 3D luam tawm. Xyoo 2024, 32% ntawm txhua tus hlau hmoov siv nyob rau hauv lub ntiaj teb yuav yog 316L hmoov. Nws cov txiaj ntsig tseem ceeb yog:
Zoo heev ntawm kev tiv thaiv corrosion: uas muaj tsawg kawg yog 10.5% chromium, ua rau nws tsis yooj yim sua hloov hauv petrochemicals thiab kev ua zaub mov noj. Ib qho Maritime platform valve chaw tsim tshuaj paus ua rau 316L stainless hlau valve siv 3D luam ntawv tshuab. Lub valve no yuav kav peb lub sijhawm ntev dua li cov qauv case castings hauv dej hiav txwv uas yog corrosive.
Qhov Txheej Txheem Siab Rau Cov Luam Ntawv: Qhov loj yaj teb pas dej muab hloov pauv hloov pauv ntawm laser zog, thiab nws muaj tus nqi ua tiav ntawm ntau tshaj li 98%. Ib qho chaw tsheb tshwj xeeb lub tuam txhab siv 12 - Laser sib tshuam tshuab los ua 12 kg ntawm stainless hlau seem hauv ib teev. Qhov no yog 8 zaug ntxiv tau txais txiaj ntsig dua ib lub tshuab ua ib-laser.
Tus tshaj tawm - Kev Ua Tshuaj Zoo yog zoo -}}}}}}}} Tsim. Piv txwv li, kev kho mob laus tuaj yeem ua rau muaj zog tso tawm, uas nce tensile lub zog ntawm 1700mpa rau 1300mpa. Ib lub pwm ruaj ruaj ua rau kev txhaj tshuaj pwm tawm ntawm cov khoom no, uas tau kawg 40% ntev dua li H13 steel steel pwm.
2. Titanium Alloy: cov khoom tseem ceeb rau lub aerospace thiab chaw kho mob
Titanium alloy ua txog 45% ntawm qhov siab-}}}}}}} end end metal ™ kev lag luam luam yeeb. Nws cov kev ntsuas thev naus laus zis feem ntau pom hauv:
TC4 (TiCO-6AL-4V) yog siv rau ntawm cov nplai loj: Koj tuaj yeem ua cov qauv sib xyaw ua ke, muaj cov muaju equatals thiab equiatals thiab equiatals los ntawm kev hloov kho lub ntsej muag kom zoo. Thaum ua ke nrog kub ostatic nias kev kho, qaug zog lub neej ntawm lub cav av muaj peev xwm ua tau 120% ntev dua li tus qauv forging. Ib yam pob zeb ua ntxaij siv cov ntsiab lus hloov tshiab Qhov no ua rau nws 35% sib zog dua thiab 28% pheej yig dua.
Kev tawg hauv biomedical cov ntaub ntawv kev tsim kho tshiab: vim tias nws yog biocompibic ntau, ntshiab titanium qib 2 hmoov tau siv hauv kev cog lus ntawm tus kheej orthopedic. Ib lub tsev kho mob tau ua ib lub duav sib koom ua ke prostheses electron nqaj melting (EBM) thev naus laus zis. Cov incthesis muaj lub porosity uas tau tswj hwm ntawm 65%%, uas ua kom nrawm nrawm ntawm kev tsim cov pob txha hlwb los ntawm peb zaug.
Ua ib qho tshiab Alloy System: Ntxiv 0.5% NB rau Kev Sib Tw Tial Intermetallic tau ua rau lawv muaj zog dua ntawm kev kub siab, mus txog 150 MPa. Qhov no ua rau lawv cov khoom siv zoo rau cov roj turbine hauv cov tshuab hluav taws xob. Siv cov phiaj xwm kev tshaj tawm (DED) thev naus laus zis thev naus laus zis tau ua rau muaj kev puas tsuaj rau ntug kev puas tsuaj rau qee hom tshuab hniav. Cov txheej kho thiab cov txheej txheem substrate muaj lub zog sib luag ntawm 420MPA.
3. Alloy Alloy: cov khoom siv uas tau pib lub teeb kev ncig
Peb qhov teeb meem tseem ceeb yog daws los ntawm aluminium alloy 3D tshuab luam ntawv tshuab:
Tshuab rau kev tswj cov kab nrib pleb kub: alsi10mg alloy muaj 6% rau 12% silicon hauv nws, uas ua rau nws tsim tsa eutsecic qauv. Qhov kev txo qis no tus naj npawb ntawm kub cov kab nrib pleb ntawm 35% kom tsawg dua 5%. Qee lub tuam txhab tshiab lub tuam txhab ua haujlwm tshiab ua haujlwm rau cov khoom siv roj teeb nkhaus. Piv rau cov qauv tuag - castting feem, cov phiaj xwm no yog 42% sib zog dua thiab 18% stiffer.
Tsim cov kab ke ua rau muaj lub ntiaj teb tsis tshua muaj zog: ntxiv 0.4% SC rau Al Mg SC ZR Alloy ua rau nws muaj zog dua 500mpa thiab me dua 1 μm. Ib lub tuam txhab Aerospace ua ib lub suab nkauj satellite tawm ntawm cov khoom no uas nyob ruaj khov hauv qhov loj ntawm -196℃thiab 200 degree.
Ib qho kev ua ntej loj hauv loj - teev tsim: ib lub tuam txhab ua luam ntawv tshuab los luam tag nrho A350 Aircraft qhov rai thav duab. Qhov kev txiav tawm no tau txiav los ntawm 22% piv rau cov kev sib tw ib txwm muaj thiab txiav cov sijhawm ntau lawm los ntawm 6 lub lis piam mus rau 72 teev.
4. Siab {{- kub alloys: tiv thaiv cov chaw hnyav
Nickel -} Raws siab- kub alloys ua kwv yees li 80% ntawm kev ua lag luam rau qhov kawg kub ntawm cov cav dav hlau. Lawv cov kev ntsuas thev naus laus zis pom ob txoj kev loj:
Tshuab rau kev tswj hwm microcacks: Peb muaj peev xwm txo qis tus nqi ntawm inconel 718 alloy los ntawm kev hloov lub zog laser hluav taws xob ntom (80-120 ³) thiab scaning spacing (0.08-0.12 hli). Ib lub tuam txhab roj turbine ua rau cov qauv siv hluav taws xob siv cov thev naus laus zis no. Cov discs no tuaj yeem kav ntev li 1000 teev ntawm 650℃thiab 350 mpa.
Cov Khoom Siv Gradient Cov Ntawv Luam Ntawv: Qhov chaw tshawb fawb tsim cov khoom siv gradient gradient phab ntsa mus los ntawm nicocaly txheej rau ib tug inconel 625 substrate nyob rau hauv txoj kev du. Qhov no ua rau cov khoom siv peb zaug tiv taus oxidation thiab muab nws lub voj thermal lub neej ntawm ntau tshaj 5000 zaug.
