Puas yog cov ntaub hlau luam ntawv yuav tsum nqus plua plav cia?

一, cov khoom siv: cov khoom siv tau los cuam tshuam nrog kev nqus cov oxidation thiab noo noo.
Muaj ob yam tseem ceeb uas ib puag ncig rau cov ntaub ntawv luam ntawv hlau yuav tsum ua: Khaws cov txheej txheem oxidation los ntawm kev tshwm sim thiab tswj cov dej noo hauv huab cua. Ob yam ob yam no cuam tshuam li cas ruaj khov thiab hloov kho cov khoom siv.
1. Qhov kev phom sij cuam tshuam ntawm oxidation kev tawm tsam
Thaum cov hlau hlau los rau hauv kev sib cuag nrog huab cua, ib cov tshuaj oxide rau saum npoo sai sai. Piv txwv li, titanium alloy hmoov sib xyaw ua ke nrog oxygen ntawm qhov kub thiab txias ua rau tio ₂. Thaum kub siab, zoo li saum toj no 650℃nyob rau hauv lub electron nqaj melting txheej txheem, tus lej oxidation nce los ntawm ntau. Muaj peb lub ntsiab nyuaj uas tuaj yeem tshwm sim thaum muaj ib txheej oxide:
Tsawg fluity: kev sib sau ntawm oxidised hais ua kom cov hmoov lub particle loj muab faib rau cov hmoov kom loj dua. Kev ua lag luam 3D 3D ua tau qhia tau tias tom qab 72 teev ntawm kev sib txawv ntawm cov titanium alloy tej hmoov tuab mus los ntawm ± 35 μ m. Qhov no tau ua rau saum npoo ntawm cov khoom luam tawm 40% rougher.
Ntau melting flaws: Oxide txheej tawg cia thaum nws raug ntaus los ntawm laser lossis electron nqaj, uas tsim cov roj thiab pore flaws. Thaum luam tawm cov aviation cav, cov hmoov av titanium oxide hmoov 2.3 ntau lub ntsej muag tswj tau hauv lub tshuab nqus tsev, thiab nws lub neej qaug zog tau txiav los ntawm 60%.
Kev tsis txaus ntseeg ntawm cov khoom siv: Oxide txheej cuam tshuam rau txoj kev uas cov hlau muaju yog npaj, uas ua rau cov hlau tsis muaj zog. Lub zog tensile ntawm 316L stainless hlau hmoov poob los ntawm 680MPA rau 520MPA tom qab oxidation, thaum lub elongation tus nqi tawm ntawm 45% mus 28%.
2. Qhov ua tau ntawm kev nqus dej noo hauv cov saw hlau
Hmoov hmoov hlau yog qhov zoo heev ntawm so noo noo los ntawm huab cua vim tias lawv muaj tus qauv ntxig. Piv txwv li, txhuas - Cov ntsiab lus noo nyob hauv ib qho chaw nrog 24/xeb cov ntsiab lus tuaj yeem ncav cuag 0.15%, uas yog siab dua cov txheej txheem kev nyab xeeb txheem ntawm 0.05%. Peb qhov kev phom sij tseem ceeb los ntawm kev nqus dej noo:
Muaj peev xwm ntawm kev sib xyaw ua ke: Thaum ntub hmoov ntub tawm tsam ib yam dab tsi lossis raug rau cov nqi ntuj qub, nws tuaj yeem ntes hluav taws rau nws tus kheej. Xyoo 2023, muaj kev tawg ntawm titanium alloy hmoov nyob rau hauv kev lag luam 3D luam tawm hauv lub teb chaws Yelemees. Qhov kev tshawb nrhiav pom tias kev sib tsoo hmoov muaj feem pua ​​yaiab ntawm 0.22%, uas muaj ntau dua li qhov muaj kev nyab xeeb.
Tsis yog cov txheej txheem ruaj khov: Lub laser ua rau cov dej evaporate tam sim ntawd, uas ua rau lub pas dej Molten nteg txaws. Ib qho chaw muag khoom Automotive cov ntaub ntawv qhia tias thaum noo noo-} absor} absor} absor} absor} mus rau 0.3% rau 2.7%, thiab cov kab ntawv sib tw tau nce los ntawm 8 zaug.
Lub hydrogen co yam tshwm sim: thaum dej so, nws tso tawm hydrogen atoms uas tau nkag mus rau hauv cov hlau tawv hlau thiab ua kom nws muaj zog tsis muaj zog. Thaum luam tawm kev ua lag luam ua rau aviawers, cov pob txha lov toding ntawm lub noo noo {· m} · · m · · · ·, uas tsis muaj zog txaus kom dhau cov pa dav hlau kom txaus.
2, cov txheej txheem phom sij: Kev tswj cov saw hlau los ntawm kev cia khoom
Txoj kev siv hlau luam ntawv yog khaws cia muaj qhov cuam tshuam ncaj qha rau kev nyab xeeb thiab ruaj khov rau cov kauj ruam tom ntej. Los ntawm kev tsim qhov chaw kaw, Hoover Cia Tshuab Tswj Peb Cov Kev Pheej Yig Tseem Ceeb:
1. Kev tswj kev nyab xeeb uas yuav tsis muaj kev tawg
Hlau hmoov yog ib hom plua plav tsis muaj plua plav, thiab nws qhov qis qis tshaj txwv (LEL) yog ze ze rau qhov loj me ntawm cov pa thiab cov pa oxygen hauv huab cua. Piv txwv li, titanium alloy hmoov muaj qis lel ntawm tsuas yog 20g / m³ tshaj txhuas hmoov, uas muaj qhov ntau dua lel ntawm 60g / m³. Cov kev hauv qab no uas Hoover Cia cov kev pheej hmoo ntawm qhov kev pheej hmoo ntawm kev tawg:
Sau lub tshuab nqus tsev nrog nitrogen lossis argon roj kom ceev cov pa oxygen hauv qab 0.5%. Qhov no hu ua kev tiv thaiv roj av. Lub tuam txhab tub rog tau ua rau pom tias thaum cov roj oxygen poob ntawm 48 MPa rau 0.02 MPa kev nyab xeeb tau nce los ntawm 40 zaug.
Kev Tiv Thaiv Kev Tiv Thaiv Zoo Li Qub: Sab hauv ntawm lub tshuab nqus tsev cia lub thawv yog them rau hauv anti {{} cov khoom siv qub uas muaj tsawg dua 10 cm. Qhov no ua rau zoo li qub zoo li qub los ntawm kev tshwm sim thaum cov hmoov txhuam tawm tsam phab ntsa.
Kev tswj qhov kub thiab txias: Lub tshuab nqus tsev huab cua sov thermal kev sib cav, thiab thaum ua ke nrog cov tub yees-tub yees, nws ua rau lub tub yees tub yees, nws ua kom qhov chaw cia ntawm 15 thiab 25 degrees Celsius. Qhov no nres kub siab los ntawm kev nrawm oxidation kev tawm tsam.
2. Qhov kev ruaj ntseg ntawm cov txheej txheem tsis
Hlau Luam Ntawv yog rhiab heev rau cov hmoov ua haujlwm zoo, thiab nqus plua plav cia tuaj yeem ua cov ntsuas tseem ceeb:
Kev faib khoom ntawm qhov loj me me: Lub tshuab nqus tsev qhov loj ua rau D50 particle loj khov kho thiab nres cov hmoov los ntawm clumping ua ke. Kev ua lag luam kev kho mob hais tias cov qauv sib txawv ntawm cov roj me me kom tswj tau hauv lub tshuab nqus tsev tau ploj mus ntawm 0.8 μm. Cov qauv hloov pauv ntawm porosity rau cov ntawv sau tseg tau ploj mus ntawm 1.2% mus rau 0.5%.
Kev ceev ceev: Cov ntau ntawm kev hloov kho kom ntev ntawm lub tshuab nqus tsev ntawm lub tshuab nqus tsev {}}} 0. ± 0.05g / cm rau à 0.01g / cm. Qhov no ua kom paub tseeb tias cov hmoov tuab tuab yog qhov qub thoob plaws.
Kev Ua Ke: Thaum cov av noo hauv cov cua nyob hauv qab 5% rh, lub kaum sab xis ntawm repding {1 Qib rau 32 degree, uas ua rau lawv 40% kua ntau.
3, kev lag luam daim ntawv thov: muaj zog thov nyob rau hauv lub siab -}}}}}}}}}}}}}}}}}}}}}}}}} Kawg tsim kev lag luam
Nyob rau hauv high -}}}}}}}}}}}}}}} impl medical} medical medical medical impl impl, thiab lub zog hluav taws xob, thiab lub tshuab nqus tsev, thiab kev ua haujlwm nov los khaws cov ntawv luam tawm hlau.
1. Lub teb ntawm Aerospace
Thaum luam ntawv roj tsis muaj ge leap tshuab, cob cov chromium alloy hmoov khaws cia rau hauv ib lub tshuab nqus tsev ua haujlwm ua peb txoj kev nce qib loj:
Siv nyiaj ntev dua: Lub nozzle rau lub tshuab nqus tsev cia hmoov cov tshuab luam ntawv tau dhau 10,000 lub voj voog thoj kuaj thiab yuav kawg peb ntev dua li cov khoom siv.
Txhim kho efficiency: porosity mus los ntawm 0.8% mus rau 0.2%, thiab roj efficiency tau nce los ntawm 15%.
Cov nqi txuag tau: cov hmoov siv hmoov tau mus ntawm 75% rau 92%, thiab tus nqi ntawm ib daim nqes mus 28%.
2. Lub ncauj lus ntawm kev mob tshuaj kho mob
Hauv kev siv tshuaj tiv thaiv 3D luam tawm ntxaij titanium alloy unuster devices, nqus khoom cia thev naus laus zis loj:
Biocompatibility: lub tshuab nqus tsev - Cov hmoov khaws cia muaj tsawg dua 0.05% impurities (o, h), uas tau raws li ISO 13782 tus qauv.
Cov nyhuv ntawm cov pob txha tsim: tus nqi ntawm cov pob txha kev loj hlob ntau dua peb lub hlis tau nce mus rau hauv lub tshuab nqus tsev, thiab tus nqi muaj sia nyob ntau dua tsib xyoos nce li ntawm 85% mus rau 97%.
3. Lub teb ntawm nuclear lub zog
Thaum ua cov yeeb yaj kiab ntws tawm rau nuclear reactors, hmoov tsis zoo nyob rau hauv lub tshuab nqus dej: nyob rau hauv lub siab ib puag ncig ntawm 560 lub mm / xyoo rau 0.005 mm / xyoo.
Neutron Kev Ua Tau Zoo: Tus nqi ntawm cov neeg Boron nyob ntawm 1.2 wt%, uas muaj kev nyab xeeb rau kev siv nuclear.
