1. Cov qib twg ntawm titanium yog qhov zoo tshaj?
Tsis muaj ib qeb "zoo tshaj plaws" ntawm cov kev xaiv zoo tshaj plaws yog nyob ntawm daim ntawv thov tshwj xeeb thiab nws cov cai. Titanium qib sib txawv hauv kev sib xyaw (cov khoom siv ntshiab, cov khoom siv kho mob corrosions, formability, thiab tus nqi, ua txhua yam rau kev siv cov neeg mob sib txawv.
Kev lag luam ntshiab (CP) Titanium (qib 1-4, 7, 11): Cov no tsis tau sau npe thiab muaj nqi rau tshwj xeeb corrosion tsis kam, biocompatibility, thiab formability. Qeb 1 yog qhov tseem ceeb tshaj plaws thiab yooj yim rau daim tab sis muaj lub zog qis tshaj plaws, ua rau nws zoo tagnrho rau kev ua yeeb yam lossis kev ua yeeb yam, tsis yog {2} cov qauv txheej txheem. Qeb 2, cov ntawv cp feem ntau, tsis muaj zog tshaj, corrosion tsis kam, thiab kev sib hloov cua sov, kev cog lus kev kho mob, thiab cov khoom siv hluav taws xob, thiab cov khoom siv marine. Qeb 4 muaj lub zog siab dua (vim yog cov ntsiab lus oxygen ntau dua) thiab yog qhov ntsuas ntawm cov txheej txheem uas yuav tsum muaj lub zog muaj zog nrog corrosion tsis kam.
Titanium alloys: Cov no muaj cov ntsiab lus, piv txwv li, vanadium, molybdenum) los txhim kho lub zog, tshav kub tawm, lossis lwm yam khoom. Ti - 6 Ntu {{}}- Lub zog muaj zog, ua kom muaj zog tshaj plaws, cov khoom siv dav hlau), cov khoom siv hluav taws xob zoo), khoom siv tsheb, thiab khoom siv kis las. Qeb 9 (ti-3al-2.5V) yog muaj nuj nqis rau nws cov weldability zoo heev thiab yog siv hauv aerospace tubing. Qib 12 (ti-0.8no-0.8ni) excrels intorsony tsis kam, haum rau kev ua yeeb yam thiab offshore roj applications.
Yog li, qib "zoo tshaj plaws" zoo tshaj plaws yog txiav txim siab los ntawm cov ntsiab lus zoo li lub zog xav tau, kev ua kom muaj kev xav tau, thiab muaj kev txwv tsis pub muaj nuj nqis.
2. Dab tsi yog cov qhab nia pheej yig tshaj ntawm titanium?
Ntawm cov qhab nia siab rau cov qib,Kev lag luam ntshiab (CP) Titanium qib 1feem ntau pheej yig tshaj. Nws tus nqi qis dua los ntawm ntau yam:
Muaj pes tsawg: Qib 1 yog cov ntaub ntawv ntshiab tshaj plaws ntawm CP Titanium, nrog qis tshaj ntawm alloy cov ntsiab (piv txwv li ntau dua lossis sib npaug lossis sib npaug nrog 0.20%). Qhov tsawg heev ntawm cov khoom kim kim (tsis zoo li titanium alloys) txo cov nqi tsim khoom.
Tab tom ua: Nws lub zog siab thiab lub zog qis ua kom yooj yim rau fabricate los ntawm kev ua haujlwm txias, uas yuav tsum muaj zog thiab cov cuab yeej tshwj xeeb piv rau muaj zog dua, ntau cov qhab nia.
Kev yuav tau: Thaum tsis yog raws li dav siv raws qib 2, qib 1 tseem tsim nyob rau hauv cov khoom tseem ceeb rau kev siv thiab corrosion resistance (es tsis tshua muaj zog) yog qhov tseem ceeb, kom muaj nqi zog thiab sib tw.
Uas tau hais tias, tus nqi tuaj yeem hloov raws li kev ua lag luam (piv txwv li, cov raj, thiab cov chaw muag khoom, tab sis yog ib qho ntawm cov feem ntau cov uas tsis muaj peev xwm xaiv. Qeb 2, txawm tias me dua me ntsis dua qib 1, feem ntau nyiam rau nws lub zog zoo dua {}} tus nqi kev lag luam zoo tshaj plaws rau ntau cov ntawv thov.
3. Dab tsi yog qhov kim tshaj plaws qib ntawm titanium?
Cov qhab nia tshaj plaws titanium feem ntauHigh - Kev Ua Tau Zoo Alloys Tsim rau cov chaw ib puag ncig heev lossis cov ntawv thov tshwj xeeb, qhov twg tshwj xeeb cov khoom (piv txwv li, ultra- lub zog siab, lossis biocompatibilities nrog cov nuj nqi siab tshaj plaws) pov thawj tus nqi. Piv txwv li:
Titanium -} Alloys Alloys (piv txwv li, Ti-6al-2Sn-4ZR-4V-2FE-2FE-3A): Cov no yog cua sov -} Cov khoom siv uas muaj zog, siv rau hauv lub zog ntawm lub zog, siv rau hauv lub zog ntawm lub zog, muaj zog) uas ua haujlwm ntawm nce qhov kub. Lawv cov lus sib xyaw ua ke (nrog ntau cov ntsiab lus kim heev xws li zirconium, molybdenum yuav tsum tau (los xyuas kom paub tseeb thiab kub tsis kam ua haujlwm.
Beta titanium alloys (piv txwv li, ti-15v-3cr-3C-3al): Cov alloks muaj cov formanity zoo tshaj, ua kom zoo tshaj plaws rau kev siv cov duab), thiab siab}} Kev ntxhov siab. Lawv cov tshwj xeeb tshwj xeeb (piv txwv li, vanadium, chromium) thiab cov txheej txheem kho cua sov nce ntau lawm.
Kev Kho Mob -} cov qib titanium alloys nrog kev txhim kho biocompatibility: Thaum cov qhab nia qauv zoo li Ti-6V-4V Eli (piv txwv li cov khoom siv kho mob tsis zoo lossis ua kom muaj kev ua haujlwm ntau ntxiv vim yog kev kuaj mob, kev coj ua, thiab kev tswj hwm kev ua raws.
Ntawm cov no,TI-6242 (Ti-6AL-2SN-4ZR-6MO)Thiab qhov siab zoo sib xws - kub iterospace ib feem ntau tau ua kom meej meej, thiab kev ua tshwj xeeb- txhua yam uas ua rau lawv tus nqi tus nqi nqi.
