Super elastic nitinol hlauyog ib qho kev ua tau zoo alloy hlau cov khoom siv hauv kev tsim khoom siv kho mob, feem ntau siv hauv plawv stents, vascular implants, kho hniav, thiab lwm yam.
Nws yog ua los ntawm npib tsib xee-titanium (Ni-Ti) alloy, uas muaj peev xwm ua tau ntau yam ntawm strain yam tsis tas yuav deformation nyob rau hauv cov duab loj deformation, thiab muaj zoo elasticity thiab qaug zog, li no lub npe "Superelastic".
Ob leeg nitinol hlau thiab Shape nco nitinol hlau yog daim ntawv loj tshaj plaws ntawm qhov tshwj xeeb superelastic thiab cov duab nco alloy, ua lag luam nyob rau hauv nruab nrab -1980s. Superelastic nitinol hlau, tseem hu ua lub cim xeeb hlau hlau, yog ib qho hlau uas muaj cov nickel thiab titanium. Nws muaj nyob rau hauv ntau qhov ntau thiab tsawg, alloys, thiab tiav. Thiab, daim ntawv nco lossis daim ntawv superelastic yog ob qho tib si muaj. Nitinol xov hlau tau txais kev siv ntau ntxiv hauv kev lag luam khoom siv kho mob rau cov hniav nyiaj hniav kub, coj cov xov hlau, paraglider, iav ncej, kev kho mob, thiab lwm yam kev siv tseem ceeb.

Titanium thiab nickel atoms nyob rau hauv nitinol alloy hlau tsim ib tug tshwj xeeb lattice qauv uas ua rau nws ua tau zoo nco thiab superelastic zog. Ntawm qhov kub thiab txias, cov hlau yog nyob rau hauv lub xeev austenitic thiab nws yooj yim rau khoov thiab deformation. Raws li qhov kub thiab txias, cov hlau hloov pauv ntawm austenite mus rau martensite, nthuav tawm cov cuab yeej superelastic xav tsis thoob.
Super elastic nitinol hlau, superelasticity yog lub cim ntuj kev ua tau zoo ntawm Nitinol hlau. Lub npe hu ua superelasticity yog siab dua qhov kub ntawm AF vim nws yog qhov yooj yim mos los yog inelastic hauv qab AF kub, yog li nws muaj chav kub superelasticity (xws li AF=25 degree) thiab qis kub superelasticity (xws li AF{{ 3}} degree).
Nitinol yog ib qho zoo-nco alloy SMA yog ib qho hlau uas muaj cov yam ntxwv: cov yam ntxwv ntawm lub cim xeeb thiab yog super-elastic, SMA tuaj yeem "nco" nws cov duab qub thiab deformed rau nws cov duab ua ntej deformed thaum rhuab. Nickle 55% Titanium 45%. Muaj kev hloov me ntsis hauv cov khoom xyaw, thiab nws yuav cuam tshuam rau cov khoom siv.
4. Cov txheej txheem tsim khoom ntawm superelastic nitinol alloy hlau suav nrog cov kauj ruam tseem ceeb hauv qab no
1) Kev npaj cov khoom siv: Cov khoom siv tseem ceeb rau kev tsim cov nitinol hlau yog npib tsib xee thiab titanium, thiab qhov purity thiab piv ntawm cov ntaub ntawv yuav tsum tau ua kom meej.
2) Smelting alloy: Nickel thiab titanium yog yaj los ntawm arc melting los yog nqus induction melting tshuab, thiab sib tov ua Ni-Ti alloy.
3) Stretching: Ni-Ti alloy yog ua tiav rau hauv filaments los ntawm lub tshuab ncab. Thaum lub sijhawm txheej txheem no, kev ua haujlwm kub thiab ncab nrawm yuav tsum tau tswj xyuas kom ntseeg tau tias cov khoom zoo.
4) Kev kho cua sov: Cov khoom siv filamentary yog kho cua sov kom muab nws cov khoom xav tau superelastic.
5) Kev kho deg: Cov khoom siv filamentary tau raug kho rau saum npoo xws li polishing thiab tu kom ntseeg tau tias nws qhov chaw du thiab tsis muaj impurities.
Qhov kawg tsim superelastic nitinol alloy hlau yuav tsum muaj kev ua haujlwm siab thiab ruaj khov kom ntseeg tau tias daim ntawv thov cuam tshuam thiab kev nyab xeeb hauv cov khoom siv kho mob.
5. Daim ntawv thov teb
1) Cov khoom siv kho mob: siv los ua cov khoom siv kho mob xws li stents thiab li qub.
2) Automotive kev lag luam: siv rau lub tsheb yuam sij, tsheb tiv thaiv tub sab nyiag, thiab lwm yam.
3) Aerospace: siv los tsim cov plhaub thiab cov khoom siv nrog cov aerodynamics siab, kev coj ua kom muaj zog, siab zog, thiab kub siab.
4) Kev tsim kho kev lag luam: rau kev tsim cov txheej txheem elastic thiab cov khoom siv.
Cov saum toj no yog daim ntawv thov teb ntawm super elastic nitinol hlau.
6. Ntim Cov Lus Qhia
- Ntim nrog daim ntawv tsis muaj dej noo.
- Ntim nrog Carton.
- Ntim nrog ua npuas ncauj yas hauv txhua sab ntawm lub thawv.
