Nitinol hlau: cov khoom siv tshiab rau kev lag luam niaj hnub thiab tshuaj
2024-06-19 10:00:00 Nws
Nyob rau niaj hnub no txoj kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis, NiTi hlau, raws li ib yam ntawm cov khoom siv ntse ntse nrog cov khoom tshwj xeeb, maj mam tau txais kev mloog zoo. Nitinol hlau yog dav siv nyob rau hauv kev kho mob, aviation, automotive thiab lwm yam teb vim hais tias ntawm nws zoo heev zoo zoo nco alloy (SMA) zog thiab superelasticity.
Ntsiab tswvyim
●Daim duab nco effect:Ib qho ntawm cov khoom tseem ceeb tshaj plaws ntawm Nitinol hlau yog nws cov duab cim xeeb. Nws txhais tau hais tias tom qab ua tiav qee qhov kev hloov kho tshuab, los ntawm cua sov nws mus rau qhov kub thiab txias, cov hlau tuaj yeem rov qab mus rau nws qhov qub preset zoo yam tsis tau tawm mus tas li deformation. Cov nyhuv no yog vim qhov hloov pauv hloov pauv ntawm cov martensite thiab austenite cov qauv ntawm Nitinol alloys ntawm qhov kub sib txawv.
●Superelasticity:Ntxiv nrog rau cov teebmeem kev nco, Nitinol cov xov hlau kuj pom zoo superelasticity. Lub alloy khaws elasticity txawm nyob rau hauv loj deformation tej yam kev mob thiab muaj peev xwm sai thiab zoo rov qab mus rau nws tus qub zoo, ua rau nws tshwj xeeb tshaj yog tseem ceeb nyob rau hauv daim ntawv thov uas yuav tsum tau nquag deformation thiab siab elastic yuav tsum tau.
●Crystal qauv hloov:Cov khoom no ntawm Nitinol feem ntau yog nyob ntawm nws cov qauv siv lead ua nyuaj. Ntawm qhov kub thiab txias, cov hlau yog nyob rau hauv ib theem martensitic thiab muaj cov formability siab. Thaum qhov kub nce siab tshaj qhov tseem ceeb, nws hloov mus rau theem austenitic, yog li rov qab mus rau nws qhov qub.
Cov teeb meem xav tau kev saib xyuas
●Kev tswj qhov kub thiab txias:Cov duab nco nyhuv thiab superelasticity ntawm lub alloy nyob ntawm qhov kub thiab txias hloov. Yog li ntawd, qhov kub thiab txias yuav tsum tau tswj nruj me ntsis thaum siv los xyuas kom meej tias cov hlau tuaj yeem ua tau raws li qhov xav tau ntawm qhov kub thiab txias.
●Fatigue lub neej:Txawm hais tias Nitinol hlau qhia tau zoo heev elastic rov qab muaj peev xwm, nws tuaj yeem cuam tshuam rau nws lub neej qaug zog vim yog lub sij hawm ntev deformation thiab muaj kev ntxhov siab. Yog li ntawd, lub durability thiab ntev stability ntawm lub alloy yuav tsum tau txiav txim siab nyob rau hauv lub tsim thiab daim ntawv thov.
●Kev siv technology:Kev ua ntawm Nitinol yog qhov nyuaj. Txiav, vuam thiab tsim cov txheej txheem yuav tsum muaj cov cuab yeej tshwj xeeb thiab cov txheej txheem. Cov kev ntsuas no pab kom tsis txhob ua rau cov hlau tsis zoo thiab cov khoom puas.
Derivative khoom
●Cov cuab yeej kho mob:Hauv kev kho mob, Nitinol hlau yog dav siv hauv plawv plawv stents, kho hniav orthotics, phais sutures thiab lwm yam khoom siv. Lawv superelasticity thiab cov duab cim xeeb tso cai rau cov cuab yeej no hloov mus rau qhov chaw sab hauv thiab muab cov txiaj ntsig kho tau ntev.
●Aerospace:Hauv kev lag luam aerospace, Nitinol hlau yog siv los ua cov khoom siv rau lub zog siab, lub teeb yuag, xws li cov qauv kev txhawb nqa elastic thiab cov khoom siv dav hlau txuas. Cov ntawv thov no xav kom cov khoom siv ua haujlwm ruaj khov hauv ib puag ncig huab cua.
●Consumer electronics:Raws li kev siv thev naus laus zis, Nitinol xov hlau tau pib siv rau hauv cov khoom siv hluav taws xob siv hluav taws xob, xws li cov ntxaij vab tshaus khoov tau hauv cov xov tooj ntawm tes thiab cov khoom sib txuas yooj yim hauv cov khoom siv hnav. Cov ntawv thov no txhim kho cov kav ntev thiab cov neeg siv kev paub ntawm cov khoom.
●Industrial manufacturing:Nitinol hlau kuj tau siv dav hauv kev lag luam tsim khoom raws li cov khoom siv ntse, xws li sensors, actuators thiab automation khoom. Nws cov duab cim xeeb tso cai rau cov cuab yeej no ua haujlwm tau zoo thiab raug raws li kev ua haujlwm sib txawv.
Zuag qhia tag nrho, raws li cov khoom siv ua haujlwm siab heev, Nitinol hlau tsis tau tsuas yog hloov pauv kev siv thev naus laus zis ntawm kev lag luam niaj hnub thiab kev kho mob, tab sis kuj coj kev tsim kho tshiab thiab kev tsim kho tshiab rau ntau yam kev lag luam. Nrog rau kev nkag siab tob txog nws qhov kev ua tau zoo thiab daim ntawv thov, nws cia siab tias nws yuav muaj ntau dua thiab nthuav dav daim ntawv thov yav tom ntej.
