Superelastic Nitinol Daim Ntawv

Superelastic nitinol ntawvtseem hu ua duab nco alloy. Lub high-temperature theem ntawm cov duab nco alloy muaj siab structural symmetry, feem ntau yog ib tug txiav txim cubic qauv. Hauv qab ntawm Ms qhov kub, qhov kub-kub theem nrog ib qho kev taw qhia ib leeg hloov mus rau hauv martensitic variant nrog txawv orientations. Thaum cov khoom deformed hauv qab qhov kub ntawm Ms los ua cov khoom, cov martensite variants nyob rau hauv cov khoom uas muaj qhov tsis zoo nyob rau hauv cov kev taw qhia kev ntxhov siab yog tsis tu ncua; cov nyob rau hauv ib tug haum txoj hauj lwm yog tas li loj hlob. Nws thiaj li hloov mus rau hauv ib feem ntawm kev txiav txim martensite nrog ib qho kev taw qhia. Yog hais tias nws yog rhuab saum toj no As taw tes dua, thaum lub qis-symmetry, ib leeg-orientation martensite undergoes thim rov qab transformation, lub yav dhau los ib leeg-orientation high-temperature theem yog tsim dua. Raws li qhov kev hloov pauv hloov pauv ntawm microstructure no, cov duab macroscopic ntawm cov khoom ntawm qhov kub thiab txias tau rov qab los, uas yog lub npe hu ua ib txoj kev nco. Lub cim xeeb ua tiav los ntawm qee cov txheej txheem tuaj yeem rov qab mus rau qhov zoo li qhov kub thiab txias thaum nws txias hauv qab Ms, uas yog hu ua ob txoj kev nco cov nyhuv ntawm superelastic nitinol alloy daim ntawv.

(1) Ib-txoj kev nco nyhuv

Cov duab nco alloys yog deformed ntawm qis kub thiab tuaj yeem rov qab tau lawv cov duab tom qab cua sov. Qhov zoo li lub cim xeeb tshwm sim uas tsuas muaj thaum lub sij hawm cua sov yog hu ua ib txoj kev nco nyhuv.

(2) Ob txoj kev nco ua haujlwm

Qee cov alloys rov qab kho qhov kub-kub theem zoo thaum rhuab, thiab tuaj yeem rov qab tau cov theem qis qis thaum txias, uas yog hu ua ob txoj kev nco.

(3) Cov nyhuv nco tag nrho

Thaum rhuab, qhov kub-kub theem zoo yog rov qab los, thiab thaum txias, nws dhau los ua qhov qis-kub theem zoo nrog tib cov duab thiab opposite orientation, uas yog hu ua tag nrho cov txheej txheem nco nyhuv.

Cov duab nco alloys uas tau tsim ua tiav suav nrog TiNi-raws li cov duab nco alloys, tooj liab-raws li cov duab nco alloys, thiab hlau-raws li cov duab nco alloys.

• Lub cim xeeb zoo: Tom qab tau khoov lossis twisted, nws tuaj yeem ploj mus los ntawm kev ua kom sov thiab rov qab mus rau nws cov duab qub, uas yog, nws muaj lub cim xeeb zoo.
• Superelasticity: Daim duab nco nitinol daim ntawv muaj superelasticity, thiab nws cov elastic modulus yog li ntawm 10 npaug ntawm cov hlau, uas tuaj yeem tiv taus qhov loj deformation thaum tuav cov elasticity zoo.
• Corrosion tsis kam: Nws muaj kev tiv thaiv corrosion zoo, tuaj yeem siv rau hauv qhov kub thiab txias, kev kub siab, thiab qhov chaw ntub dej, thiab tsis yooj yim cuam tshuam los ntawm ib puag ncig sab nraud.
• High-temperature stability: Cov duab nco nitinol phaj tseem muaj cov khoom siv zoo ntawm qhov kub thiab txias, thiab nws cov duab nco muaj nuj nqi thiab superelasticity tseem muaj.
• Machinability: Nws tuaj yeem ua tiav rau hauv cov duab sib txawv thiab siv rau hauv ntau qhov chaw, xws li cov khoom siv kho mob, qhov chaw pib, aerospace, thiab lwm yam.

Feem ntau, nws muaj qhov zoo ntawm cov duab nco, superelasticity, corrosion resistance, high-temperature stability, thiab processability, thiab tau dav siv nyob rau hauv ntau lub teb.

Nws yog ib daim ntawv hlau nrog cov khoom zoo, nws cov ntawv thov tseem ceeb suav nrog:

1) Cov cuab yeej kho mob: Nws tuaj yeem siv los ua cov cuab yeej kho mob xws li stents, clamps, thiab catheters rau kev phais thiab kev kuaj mob thiab kev kho mob, xws li vascular stents, lub plawv valve stents, endoscopic clips, thiab lwm yam.

2) Aerospace: Nws tuaj yeem siv los ua cov khoom siv hauv aerospace, xws li cov cav ntoo, cov khoom siv dav hlau, cov khoom siv hluav taws xob thermal, thiab lwm yam.

3) Kev tsim tsheb: Nws tuaj yeem siv rau hauv kev tsim cov khoom pib, xws li nres calipers, cav li qub, clutch siab daim hlau, thiab lwm yam.

4) Kev tsim kho tshuab: Nws tuaj yeem siv los tsim ntau yam khoom siv kho tshuab, xws li li qub, lub cev twj tso kua mis, cov dej ntws, thiab lwm yam.

Superelastic nitinol daim ntawv tseem tuaj yeem siv rau hauv kev tsim khoom ntawm cov khoom siv hluav taws xob, kev sib txuas lus, kev tsim kho, thiab textiles.
