Nitinol zoo li nco alloy(NiTi alloy), tseem hu ua nco alloy lossis nco alloy, yog cov khoom siv tshwj xeeb alloy nrog lub cim xeeb. Nws muaj peev xwm hloov cov duab raws li qhov kub thiab txias los yog sab nraud quab yuam thiab tuaj yeem rov qab mus rau nws cov duab memorized.
Kev siv tshuab
Kev siv thev naus laus zis ntawm NiTi cov duab nco alloy hlau yog qhov tseem ceeb rau kev ua haujlwm thiab qhov zoo ntawm cov khoom kawg. Nov yog qee qhov sib xws
1. rub
Kev kos duab yog ib txoj hauv kev uas cov nickel-titanium alloy blanks tau npaj rau hauv cov xov hlau los ntawm cov txheej txheem ncab. Los ntawm kev kho cov duab nrawm thiab qhov kub thiab txias, txoj kab uas hla thiab txhua yam ntawm cov hlau tuaj yeem tswj tau.
2. Kev kho cua sov
Kev kho cua sov yog ib txoj kev ua haujlwm uas txhim kho cov qoob loo ciam teb thiab cov khoom ntawm cov hlau los ntawm kev tswj qhov kub thiab lub sijhawm. Cov txheej txheem kev kho cua sov feem ntau suav nrog kev daws teeb meem, kev kho kev laus, thiab kev kho isothermal hysteresis.
3. Kev kho deg
Kev kho deg yog txhawm rau txhim kho cov khoom nto thiab zoo li cov nickel-titanium zoo nco alloy hlau. Cov kev kho saum npoo feem ntau suav nrog electrochemical polishing, electroplating, thiab txau.
4. Muaj feem cuam tshuam
Qhov zoo thiab kev ua tau zoo ntawm nickel-titanium zoo nco alloy hlau ua yog cuam tshuam los ntawm ntau yam:
5. Kub
Kev ua haujlwm kub muaj qhov tseem ceeb ntawm cov nplej loj thiab microstructure ntawm nickel-titanium zoo nco alloy hlau. Kev ua haujlwm ntawm qhov kub sib txawv ua rau muaj qhov sib txawv ntawm cov khoom siv thiab ua rau lub cim xeeb zoo.
6. Deformation tus nqi
Tus nqi deformation yog hais txog qhov ceev ntawm cov hlau yog stretched los yog compressed thaum ua. Tus nqi deformation ntau dua yuav ua rau muaj kev ntxhov siab ntau dua hauv cov khoom, yog li cuam tshuam rau cov khoom siv hluav taws xob ntawm cov hlau.
7. Alloy muaj pes tsawg leeg
Alloys nrog sib txawv muaj pes tsawg leeg muaj qhov sib txawv ntawm lub cim xeeb thiab cov khoom siv kho tshuab. Kev hloov kho rau cov alloy muaj pes tsawg leeg tuaj yeem hloov pauv cov hlau cov duab nco qhov kub thiab txias.
Hauv cov ntsiab lus, kev siv tshuab ntawmsiab zoo Nitinol zoo nco alloy hlauthiab nws cov txiaj ntsig cuam tshuam yog tus yuam sij rau kev ua tiav cov khoom zoo thiab txhim khu kev qha. Los ntawm kev ua kom zoo dua cov txheej txheem kev ua haujlwm thiab kev tswj hwm qhov cuam tshuam, nickel-titanium duab nco alloy hlau khoom nrog cov khoom zoo heev tuaj yeem tau txais.
