Nitinol Tube thiab Capillary

Nitinol Tube thiab Capillary Description

Nitinol, ib qho alloy ntawm npib tsib xee thiab titanium nrog kwv yees li tsib caug feem pua ​​​​nickel, yog cov hlau tsis ntev los no uas tau siv nws lub npe los ntawm nws cov muaj pes tsawg leeg thiab qhov chaw uas nws tau tsim (Nickel Titanium-Naval Ordnance Laboratory).

Txij li thaum nitinol kuj muaj lub peev xwm tshwj xeeb los hloov mus rau cov kab mob txawv txawv thiab sib haum nrog tib neeg lub cev nws tab tom nrhiav ntau daim ntawv thov hauv kev kho mob. Thaum kub siab dua, nitinol xav tias lub cubic crystal qauv hu ua austenite (tseem hu ua niam txiv theem). Ntawm qhov kub thiab txias, nws hloov pauv mus rau qhov nyuaj 'monoclinic' crystal qauv hu ua martensite. Qhov kub ntawm qhov austenite hloov mus rau martensite feem ntau hu ua qhov hloov pauv kub - tshwj xeeb tshaj yog, martensite pib tsim ntawm qhov hu ua Ms kub, thiab qhov kub ntawm qhov nws ua tiav yog hu ua Mf kub. Ob lub ntsej muag ntawm nws cov qauv-zoo li lub cim xeeb thiab cov khoom siv superelastic- tso cai rau nitinol los nthuav tawm cov lus teb rov qab mus rau qhov kev ntxhov siab uas nws tus kheej yog tshwm sim los ntawm kev hloov pauv theem ntawm austenitic thiab martensitic theem ntawm cov siv lead ua.

Qhov tseem ceeb rau nitinol cov khoom yog ob qho tseem ceeb ntawm kev hloov pauv theem no. Ua ntej yog tias qhov kev hloov pauv yog 'rov qab', lub ntsiab lus tias cua sov saum toj no qhov kev hloov pauv kub yuav rov qab cov qauv siv lead ua mus rau theem yooj yim austenite. Lub ntsiab lus tseem ceeb thib ob yog qhov kev hloov pauv ntawm ob qho kev qhia yog instantaneous.

Martensite tus qauv siv lead ua muaj qhov tshwj xeeb muaj peev xwm ua rau muaj kev txwv tsis pub deformation yam tsis muaj kev cuam tshuam atomic bonds. Hom kev deformation no yog hu ua twinning, uas muaj cov kev hloov kho ntawm cov dav hlau atomic yam tsis ua rau lub cev deformation mus tas li. Nws muaj peev xwm dhau mus txog 6-8 feem pua ​​​​ntawm cov kab mob no.

Thaum martensite raug xa rov qab mus rau austenite los ntawm cua sov, tus qauv austenitic qub raug xa rov qab, tsis hais seb lub sijhawm martensite puas tau deformed. Yog li lub npe 'zoo li lub cim xeeb' yog hais txog qhov tseeb tias cov duab ntawm lub siab kub austenite theem yog 'nco', txawm tias cov alloy yog deformed loj heev ntawm qhov kub thiab txias.

Nitinol raj kuj tseem siv rau hauv kev kuaj ntshav, kuaj ntshav, thiab orthopedics, nrog rau lwm yam kev siv. Qhov zoo tshaj plaws paub daim ntawv thov ntawm nitinol raj yog ua rau nws tus kheej nthuav stents ntawm laser txiav. Nws yog ib qho kev xaiv nrov hauv peripheral vascular daim ntaub ntawv. Stents tuaj yeem tsim los ntawm lub cev kub, deformed lossis folded me me ntawm lwm qhov kub, ces muab tso rau hauv cov hlab ntsha uas nws yuav rov qab mus rau nws qhov kub thiab txias thiab rov qab yog qhov qub. Kev hloov pauv theem kuj tso cai rau lub cuab yeej kom rov zoo tag nrho tom qab nws tau khoov mus rau tus nqi siab (txog 7 feem pua). Concentricity tswj thiab zoo nto tiav ntawm lub raj sab hauv txoj kab uas hla yog qhov tseem ceeb rau cov txiaj ntsig zoo thaum ua stents.

SSC tshwj xeeb hauv kev tsim cov nitinol raj thiab capillary rau ntau daim ntawv thov.
