Qhov sib txawv ntawm Titanium Gr1 thiab Gr2
Nyob rau hauv high -}}} Cov Khoom Siv, Titanium Alloys tau dhau los ua lawv cov khoom siv, thiab corrosion {{2 {rawist cov khoom. Thaum ob pawg qib ntawm kev lag luam ntshiab Titanium, Gr1 (TA1 (TA2), yog cov qhab nia theem pib hauv kev sib xyaw, kev ua tau zoo, thiab cov xwm txheej ua tau zoo.
Tshuaj Muaj Tshuaj
Cov tub ntxhais sib txawv ntawm Gr1 thiab Gr2 Cov Qauv ntawm kev kho tau yooj yim hauv lawv cov tshuaj muaj pes tsawg leeg. Gr1, lub purest kev siv hluav taws xob ntshiab ntshiab rau 99.5% titanium, tsuas yog xaiv cov nyiaj ntawm cov impurities xws li nitrogen, oxygen, thiab hlau. Qhov kev coj dawb huv no imparts tshwj xeeb corrosion tsis kam, ua rau nws ruaj khov rau hauv kev txo me me acid thiab dilute sulfuric acid.
Gr2, txhim kho nws txoj kev ua tau zoo los ntawm "cov ntsiab lus titanium yog qis dua, nws tau sib xyaw nrog 0,25% Oxygen thiab tsawg dua 0.3% hlau. Oxygen, vim yog cov tshuaj-tov zog ntxiv dag zog, thaum hlau txhim kho kev ua tau zoo los ntawm kev ua kom zoo li cov noob nplej. Qhov no tsim qauv tsim no tso cai gr2 los tswj hwm corrosion ua kom tiav 20% -30% nce rau hauv lub zog piv rau Gr1.
Ib qho piv txwv: hauv cov khoom siv desalination, gr1, vim nws lub siab purity, yog siv los tsim cov cua sov ua kom zoo, tiv thaiv cov chloride ion corrosion. Gr2, ntawm qhov tod tes, feem ntau ua rau hauv siab lub nkoj zoo li vim nws lub zog, tso cai rau nws tiv thaiv cov kev ntsuas siab dua.
Cov Khoom Siv Neeg Kho Tshuab
GR1 cov cuab yeej siv neeg tuaj yeem piav qhia raws li "yoog tau los yog" Cov khoom no ua rau nws zoo tagnrho rau kev ua haujlwm txias- packing ua kom yooj yim thiab ncab} Cov txheej txheem du uas tau tshem tawm qhov xav tau kom muaj dua polishing.
Gr2, ntawm qhov tod tes, ua kom pom qhov "ua ke ntawm lub zog thiab hloov pauv tau ntau dua li 276 mpa, thaum tswj kev elongation ntau dua 20%. Nws lub zog siab dua ua rau nws haum rau cov ntawv thov yuav ua rau muaj kev thauj khoom zoo, uas yuav tsum tawm tsam centrifugal rog thaum muaj kev sib hloov ceev. Gr2 lub zog ua kom muaj kev nyab xeeb qauv, thaum nws cov kev nruj me ntsis tiv thaiv brittle fracture tshwm sim los ntawm kev ntxhov siab.
Cov ntaub ntawv sib piv: nyob tib tuab, gr2 kev ntsuas siab muaj 30% ntxiv kom tiv thaiv hluav taws xob li 15%
Cov yam ntxwv ua
GR1 kev ua kom tau zoo dua nyob rau hauv nws qhov qis qis rau nkag mus nkag: nws qis hardness (HB110) thiab kev ua kom zoo (HB110) thiab ua kom zoo rau nws tau txiav, weld, thiab tshuab. Piv txwv li, hauv kev kho mob teb, Gr1 tuaj yeem tsim ncaj qha los ntawm CNC Milling, ua tiav qhov kev sib ntsib saum npoo tsawg dua RA0.8μm, ntsib biocompatibility. GR1 kuj ua pov thawj zoo rau weldability, nrog weld zog tom qab Argon arc vuam ntau dua li 90% ntawm cov niam txiv cov khoom thiab tsis muaj kev sib tsoo thermal.
Ua Gr2 yuav tsum tau ceevfulous kom meej: thaum nws weldability yog sib piv rau cov kev xav tau ntau dua ntawm kev txua thiab machining. Thaum tig, gr2 generates 15% {-}} le kev siv ceev ntau dua gr1}}}}}}}}}}}}}}}. Milling yuav tsum tau qis - milling kom txo qis kev co. Txawm li cas los xij, Gr2 Cov hmoov metallurgy Technology pab tau ntau yam ntawm cov khoom siv dav hlau, muaj cov khoom siv dav hlau siv los ntawm 30%.
Kev Xyaum Tswj Kev Lag Luam: Ib qho chaw nres tsheb ntawm ntug kev siv hluav taws xob siv Gr2 Titanium alloy los tsim cov twj tso kua ntsha valve lub cev. Kub iSostatic nias (duav) tshem tawm sab hauv kev puas tsuaj, uas ua rau muaj kev kub ntxhov ntau yam piv rau Gr1.
Cov Kev Siv Raug Raug
Gr1 daim ntawv thov qhia tsom rau "Corrosion tsis kam thiab ua rau kev nthuav dav." Hauv kev lag luam tshuaj, reactors tau ua nrog nws tuaj yeem tiv thaiv Nitric acid corrosion hauv qab 60%. Hauv cov teb kho mob, lub clastic mapulus ntawm gr1 cuav sib koom tes (kwv yees li ntawm 100 GPA) yog ze rau ntawm tib neeg cov pob txha, txo cov kev tiv thaiv "kev ntxhov siab tiv thaiv cov nyhuv." Hauv cov neeg siv khoom siv hluav taws xob, qee hom ntawm siab {{}}}} Cov Midhocium, ua tiav thaum tseem ua tiav cov xim zoo nkauj los ntawm anodizing.
Gr2, ntawm qhov tod tes, tau dhau los ua cov lus ntuas nrog "lub zog siab thiab corrosion tsis kam." Hauv Aerospace, nws cov account rau ntau dua 60% ntawm lub titanium siv nyob rau hauv qee lub dav hlau neeg caij tsheb, qhov rooj, thiab lwm yam txheej txheem. Nyob rau hauv cov roj ntau lawm, Gr2 tho kav tuaj yeem ua haujlwm stables nyob rau hauv ib puag ncig hauv av ntawm 350℃thiab 50 mpa. Hauv kev lag luam marine, ib submarine siv gr2 titanium alloy siab Hulls, nce nws qhov kev dhia dej dhia ntev los 20%.
Kev tso tsheb ua lag luam hydrogen kev lag luam, thaum gr2, yog maj mam hloov cov stainless hlau hauv electrolyzer clippets.
Qhov sib txawv ntawm Gr1 thiab Gr2 cov lus dag nyob rau hauv cov lus teb meej ntawm cov khoom tsim qauv los thov cov cai. Rau cov ntawv thov uas xav tau huab corrosion tsis kam lossis ua txoj kev ua tiav, Gr1 yog cov kev daws teeb meem zoo tshaj plaws; Rau cov ntawv thov uas xav tau kev sib npaug ntawm lub zog thiab tus nqi, Gr2 muaj tus nqi ntau dua.
