Yog titanium {-} nickel alloy hlau ib cov khoom siv hluavtaws
Hauv kev txiav - ntug teb, cov khoom siv ntse, thiab cov khoom muaj zog, cov khoom siv nickoy nyob ntsiag to. Nws tuaj yeem rov qab mus rau nws cov duab qub tom qab tau sib ntswg, tseem nyob ruaj khov nyob rau hauv ib puag ncig huab, thiab tuaj yeem cog rau hauv tib neeg lub cev ua lub zog kho mob tas mus li. Qhov no yog sci - fi cov khoom siv ib txwm muaj "tus ntsuj plig hlau" lossis cov khoom lag luam ntawm tib neeg? Cov lus teb nyob rau nws muaj pes tsawg leeg thiab cov txheej txheem tsim khoom lag luam -}}}}}}}}}}}}}}}}} econolization embody breakroughs nyob rau hauv cov ntaub ntawv science.
"Cov genethetic" ntawm titanium - ni ni alloy hlau
Titanium -} nickel alloy xaim yog {-}} muaj kab sib piv (ib txwm 1: 1). Qhov kev sib xyaw ua ke no tsis yog ib qho kev tshwm sim ib txwm muaj, tab sis cia li ua "cov qauv" ua tib zoo siv los ntawm cov kws tshawb fawb kev ua tau zoo.
Qhov kev xaiv rau kev xaiv cov khoom lag luam: Titanium lub teeb yuag, muaj lub zog siab, thiab corrosion tsis kam lees txais kev sib txawv thiab kev nco qab. Los ntawm kev kho cov feem sib piv ntawm ob, lub txheej txheem qib theem yuav tuaj yeem tswj tau qhov tseeb ntawm 37 degree), ua rau}}} thov deformation hauv kev mob tshuaj tiv thaiv kev tshuaj tiv thaiv kev tshuaj tiv thaiv mob.
Kev nyuaj siab ntawm cov txheej txheem hluavtaws: los ntawm smthates ntawm siab {{096%) thiab nrawm rau ntawm 99.8%) thiab nrawm nrawm rau thaum lub sij hawm nqus kos duab, txhua kauj ruam yuav tsum nruj dua rau cov qauv.
Kev ua tau surpasses uas ntawm ib tug neeg cov ntsiab: ntshiab Titanium ua lub zog ntawm qhov kub tsawg, thaum ntshiab npib tsis muaj qhov cim xeeb. Txawm li cas los xij, Titanium -}}}}}} xee xees xaim, los ntawm synthesis, ua tiav ib qho kev tawg: "{}}> 2." Nws cov superelasticity (nrog rau 8% -10% hom tsis muaj kev cuam tshuam nrog kev tsis sib haum xeeb) thiab nkees tsis kam (ua haujlwm tsis zoo<5% after millions of cycles) far surpass those of either metal alone.
Lub "SCHRHETCE kom tau zoo dua" ntawm Titanium - ni ecoy xaim
Raws li cov khoom siv hluavtaws, titanium -}}}}} ecloy hlau kev ua tau thiab ua kom zoo rau cov kev xaiv sib txawv hauv ntau thaj teb. "Transformers" hauv kev kho mob
Vascular stents: nickel - titanium xov hlau, woven rau hauv mesh, tau compressed ntawm tsawg kub thiab ntxig rau hauv ib txoj hauv kev. Ib zaug hauv cov nkoj mob, lawv tau nthuav dav rau hauv cov lus teb rau lub cev kub, txhawb txoj kev mob ntsws. Lawv lub superelasticity adapts rau vascular pulsation, txo kev rov qab los.
Orthopedic kev cog lus: Nickel - daim phiaj titanium yog siv los kho lub ntsej muag pob txha. Los ntawm "thermal - kev siv tshuab" kev cob qhia thaum muaj qhov txias rau cov pob txha yooj yim dua rau kev kho kom haum.
Cov lus qhia thiab occluders: 0.3 {- 0.6 hli npib tsib-titorewires, ua tsaug rau lawv elasticity, tuaj yeem hloov pauv cov kab me me. Cardiac occluders siv lawv cov duab nco txog kom muaj qhov tsis xws luag.
Ib qho "cua sov - tiv taus tub rog" hauv aerospace teb
Nitinol alloy xaim muaj qhov taw tes melted ntawm 1310℃thiab tswj nws cov nyhuv nco nyob rau hauv kub los ntawm -196℃rau 350 degree. Hauv lub dav hlau tshuab, nws yog siv los tsim cov ntsaws ruaj ruaj uas tswj hwm kom haum txawm nyob rau hauv cov dej sov thiab siv roj. "Tus kav hlau txais xov" hauv lub teb ntse
Los ntawm manipulating hloov theem hloov chaw ntawm nickel - titanium alloy hlau, nws tuaj yeem ua rau hauv cov xaim hluav taws xob, nws tuaj yeem ua rau hauv qhov ntsuas kub lossis ua haujlwm. Piv txwv li, hauv cov neeg hlau hluav taws, nickel - Cov hlau titortor, cia li sib cog lus thaum raug rau qhov kub thiab txias los ua lub tswb ceeb toom. Hauv cov tsom iav ntse, nws ua haujlwm ua pob khawm, ua rau lub rooj qhib thiab kaw cov tuam tsev.
Ob npaug -}} edged ntaj ntawm cov khoom siv hluavtaws
Txawm tias muaj kev ua tau zoo ntawm titanium -}}}} Cov xee hlau, nws cov hluavtaws hluav taws xob kuj tseem nthuav tawm ob txoj kev sib tw tseem ceeb:
Biosafety contrepety: npib tsib xee yog chav kawm kuv carcinogen. Txawm li cas los xij, kev kho mob oxidation (sib sau ua cov ntaub ntawv tuab Cov ntaub ntawv kuaj mob qhia tias kev kho mob-}}} titanium alloy tso tawm cov ntaub so ntswg
Tom qab 10 xyoo ntawm kev cog hniav yog tsawg dua 2%.
Kev ua cov nqi siab: los ntawm raw khoom purification kom laser engraving, tus nqi ib t ton- titanium alloy xaim yog ntau dua 50 zaug ntawm cov hlau dog dig. Txawm li cas los xij, nrog cov lus qhia ntawm 3D tshuab luam ntawv thev naus laus zis, kev tsim tawm ntawm cov nyom tau nce ntxiv los ntawm 40%, paving txoj hauv kev rau lawv cov ntawv thov loj- nplai.
Cov ntaub ntawv thov rov hais dua ntawm cov khoom siv hluavtaws hauv lawv lub peev xwm los defy qhov kev xav pom tias "ntuj yog qhov zoo tshaj plaws." Txhua qhov tsis zoo thiab rov qab ntawm lub titanium -}}}} Cov ntaub ntawv xov hlau, los ntawm kev tshawb fawb ntawm lub cev tab sis kuj nthuav ntawm cov ciaj ciam ntawm lub neej. Qhov no yog kab tias qhov tseem ceeb tshaj plaws ntawm cov khoom siv hluavtaws {}}} lawv tsis yog ib qho kev cia siab alloys "uas ua kom tib neeg los tshawb txog qhov tsis paub.
