Qhov sib txawv ntawm qib 1 titanium thiab qib 5 titanium
Titanium hlau coj tus yuam sij hauv aerospace, kho mob, kev sib kho nrog nws cov teb uas muaj kev ua haujlwm biocompatibility, corrosion tsis kam thiab muaj lub zog zoo. Txawm li cas los xij, Titanium cov ntaub ntawv tsis yog ntawm ib hom. Raws li qhov sib txawv ntawm kev coj dawb huv thiab tag nrho muaj pes tsawg leeg, cov qauv thoob ntiaj teb faib lawv mus rau qib 1 txog qib 5 titanium. Cov qhab nia sib txawv muaj qhov sib txawv tseem ceeb hauv cov khoom muaj pes tsawg leeg, cov khoom siv mechanical thiab kev thov cov xwm txheej. Nkag siab cov kev sib txawv no yog qhov tseem ceeb rau cov khoom xaiv thiab kev siv engineering.
Cov Khoom Siv Cov Khoom Siv: Gradient Tsim ntawm Purity thiab Alloy Ntsiab
Qib 1 titanium:Nrog kev ua tub ntxhais siab ua ke yog cov ntsiab lus titanium feem ntau yog nyob rau sab saud (oxygen, hydrogen, hlau) yog nruj me ntsis tswj ntawm qib qis heev. Cov qauv tsim no muab nws zoo tshaj plaws corrosion tsis kam, tshwj xeeb rau kev ua kom haum ib puag ncig muaj zog xws li muaj zog acids, muaj zog alkalis thiab dej hiav txwv. Nws cov yam ntxwv tsis loj kuj tseem ua kom biocompatibility, ua rau nws txoj kev xaiv zoo tshaj plaws rau kev cog hniav kho mob.
Qeb 4 Titanium:Nws belongs rau cov qeb ntawm kev lag luam ntshiab titanium, thiab cov kev txwv sab sauv ntawm cov ntsiab lus tsis huv yog nce mus rau 0.4%. Los ntawm kev ua haujlwm dhau los, nws lub zog yog ntau dua li ntawm qib 1 titanium, thaum tswj hwm kev ua kom zoo. Qhov kev tshuav no ua rau nws dav siv hauv cov xwm txheej uas yuav tsum muaj qee lub zog thiab corrosion tsis kam, xws li siv tshuaj chemical, thiab lwm yam.
Qeb 5 Titanium:Raws li ib txwm + hom titanium alloy, nws cov Cheebtsam tseem ceeb yog 90% titanium, 6% aluminium thiab 4% vanadium. Aluminium txhim kho lub zog los ntawm cov teeb meem txuag zog, thiab vanadium reepines franters los txhim kho kev nruj thiab txhim kho cov kev ua haujlwm kub. Qhov kev tsim qauv alloy ua nws muaj lub zog siab, muaj zog thiab cov khoom siv kub zoo, ua rau cov khoom siv uas nyiam tshaj plaws hauv cov nplooj ntawv qib siab.
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab: Kev sib koom tes ua kom zoo ntawm lub zog, kev ua nruj thiab cov khoom siv roj ua kom zoo nkauj
Muaj Zog Abient:Ntawm qib 1 titanium rau qib 5 titanium, lub tensile lub zog nce kev nthuav dav. Lub tensile lub zog ntawm qib 1 titanium yog 240-345mpa, thiab tensile lub zog muaj zog, thiab lub tensancium tuaj yeem ua haujlwm txias 1100mpa kom dhau ntawm kev kho cua sov. Qhov no muaj zog ua rau titanium alloy dhia los ntawm lub teeb yuag cov khoom siv rau cov khoom siv high-zog engineering.
Pob zeb nyuaj:Lub pob txha me ntawm qib 5 Titanium yog qhov zoo dua li ntawd ntawm ntshiab titanium, thiab nws tus nqi tuaj yeem ncav cuag li 300-400mpa · m (1/2) ntawm qib 1 titanium. Lub siab nruj ua rau nws tiv thaiv kev cuam tshuam cov thauj khoom thiab cov xwm txheej tsis txaus siab, thiab yog qhov haum rau cov xwm txheej nyuaj xws li lub dav hlau lub cav thiab nkoj transircers.
Kev ua phem:Lub zog nkees muaj lub zog ntawm qib 5 Titanium ncav 510MPA (10⁷ Cycles), thaum hais tias ntawm qib 4 titanium tsuas yog 300MPA. Qhov sib txawv no cov qauv los ntawm cov qauv nplej zoo thiab cov khoom faib tawm ntawm qib 5 titanium, uas ua rau nws tsis tshua muaj kev cuam tshuam rau hauv cov kev pab cuam lub neej ntawm cov khoom.
Elastic modulus:Elastic modulus ntawm txhua qib ntawm titanium yog nruab nrab ntawm tib neeg cov pob txha (10-30gpa) thiab qib 4 titanium yog 110gpa, thiab qib 5 titanium yog 113GPA. Qhov no "Intermediate Modulus" tus yam ntxwv tuaj yeem txo cov kev ntxhov siab ntawm cov nyhuv kev cuam tshuam thiab txhawb cov pob txha sib xyaw ua ke, thiab muaj qhov zoo sib xyaw ua ke.
Daim Ntawv Thov Kev Ua Haujlwm: Daim Ntawv Qhia Kev Them Nyiaj los ntawm kev lag luam los txiav cov thev naus laus zis
Qib 1 titanium:Tej zaum yog tsom rau corrosion-resistant cov xwm txheej kub, xws li nitric acid sov hloov pauv thiab chlor-alkali cov khoom siv ntau lawm hauv kev lag luam marine engineering. Nws cov kev ua haujlwm ntawm roj ntsha kuj ua rau nws xaiv thawj zaug rau kev siv kev kho mob tsis thauj khoom, xws li pob txha taub hau thiab cov vaj tse Pacemaker.
Qeb 4 Titanium:Nrog rau qhov sib npaug ntawm lub zog thiab tus nqi, nws yog dav siv hauv cov xwm txheej uas yuav tsum muaj qee yam peev xwm. Hauv kev lag luam tshuaj, nws yog siv los tsim cov khoom siab-resistant lub thawv ntim khoom thiab xov xwm; Hauv marine engineering, nws tau dhau los ua cov khoom siv rau nkoj propellers thiab cov chaw nres nkoj tob. Ntxiv rau, qib 4 titanium muaj kev ua tau zoo heev txias thiab tuaj yeem siv los tsim cov khoom ua cov txheej txheem xws li kiv thiab ncab ncab thiab ncab ncab.
Qeb 5 Titanium:Dominates lub high-end kev ua lag luam, tshwj xeeb tshaj yog nyob rau thaj chaw uas muaj cov cai nruj ntawm cov khoom ua tau zoo. Hauv Aerospace teb, nws yog siv los tsim cov qhov tseem ceeb xws li lub cav compressor discs thiab cov casings; hauv marine engineering, nws ua cov khoom tseem ceeb rau kev sib sib zog nqus-hiav txwv hone-resistant plhaub; Hauv cov teb kho mob, nws yog siv los tsim cov pob txha pob txha pob txha pob zeb ua kom cov rog siab thiab lub sijhawm ntev.
Kev Tshawb Fawb Kev Tshawb Fawb: Ib txoj kev yeej los ntawm cov ntshiab titanium rau kev siv
Kev txhim kho ntawm cov khoom siv titanium tau undergone qhov kev hloov pauv tseem ceeb los ntawm cov ntshiab titanium rau kev siv. Nyob rau hnub thaum ntxov, qib 1 titanium muaj siab heev thiab muaj zog corrosion tsis kam, tab sis tsis muaj zog siv tau nws daim ntawv thov ntau. Hauv xyoo 1950, kev loj hlob ntawm qib 5 titanium (ti-6al-4V) nce nws lub zog ntawm txhuas thiab vanadium, thaum tswj hwm zoo corrosion tsis kam. Nkag mus rau 21st caug xyoo, cov ntaub ntawv tshiab xws li cov khoom siv titanium-zirmonecs muaj ntxiv kom zoo tshaj plaws hauv chaw kho mob los ntawm kev txhim kho kev ua haujlwm Elastic thiab txhim kho kev ua haujlwm roj ntsha.
Qhov kev muab qhab nia ntawm cov ntaub ntawv titanium yog qhov tseem ceeb yog kev kos duab ntawm kev ntsuas kev ua tau zoo thiab tus nqi. Qib 1 Titanium muab kev txhim khu kev qha corrosion tsis kam ntawm tus nqi qis thiab haum rau cov xwm txheej tsis-cov kev sib tw; Qeb 4 titanium tawm ib qho sib npaug ntawm lub zog thiab kev khwv nyiaj txiag kom tau raws li nruab nrab load yuav tsum tau; Qeb 5 titanium dominates lub siab kawg-kawg airmerress teb nrog nws cov kws kho zoo heev cov khoom siv thiab kav ntev.
