Puas yog Titanium alloys sib nqus?

Titanium alloys tau txais kev saib xyuas muaj txiaj ntsig zoo hauv ntau qhov kev lag luam vim lawv lub zog siab - rau - qhov hnyav piv, thiab biocompatibility. Ib lo lus nug uas feem ntau tshwm sim yog tias titanium alloys muaj sib nqus. Cov lus teb tsis ncaj raws li nws nyob ntawm ntau yam.

Cov hauv paus ntawm Magnetism
Ua ntej yuav hauv lub magnetism ntawm titanium alloys, nws yog qhov tseem ceeb kom nkag siab txog cov sib txawv ntawm cov hlau nplaum. Muaj peb hom tseem ceeb uas cuam tshuam rau cov hlau: Ferromagenetic, paramagnetic, thiab diamernetic. Ferrosnnetic cov ntaub ntawv, xws li hlau, npib tsib xee, thiab cob qhia, yog muaj zog nyiam ua ib qho sib nqus thiab tuaj yeem khaws lawv cov hlauetization txawm tias tom qab daim teb sab nraud tau raug tshem tawm. Paramagagetic cov ntaub ntawv tsis muaj zog nyiam rau ib daim teb sib nqus, thiab lawv cov hlauetizes ploj thaum lub teb sab nraud yog tshem tawm. Cov ntaub ntawv diamnetic, ntawm qhov tod tes, tsis muaj zog rickelled los ntawm kev sib nqus.

Titanium thiab nws cov alloy 'tus cwj pwm sib nqus
Ntshiab titanium yog paramagnetic. Qhov no txhais tau tias nws muaj lub zog nyiam ua kom muaj kev sib nqus. Lub paramagnetic xwm ntawm titanium yog vim muaj cov hluav taws xob tsis tau hauv nws cov qauv atomic. Thaum muab tso rau hauv daim teb sib nqus, cov neeg hluav taws xob tsis muaj hluav taws xob nrog cov teb, tsim lub sijhawm sib nqus tsis muaj zog.

Txawm li cas los xij, thaum titanium yog txuam nrog lwm cov ntsiab lus, cov khoom sib nqus muaj peev xwm hloov tau. Qee cov ntsiab lus tso tawm tuaj yeem txhim kho lossis tsim kev coj tus cwj pwm sib nqus ntawm lub txiaj ntsig. Piv txwv li:
- Kev sib txuas nrog cov ntsiab lus ferrigagnetic: Yog tias titanium yog txuam nrog cov tseem ceeb ntawm ferrigagnetic cov khoom xws li cov khoom siv hluav taws xob muaj peev xwm ua cov khoom siv hluav taws xob. Qhov sib ntxiv ntawm cov ntsiab lus qhia cov tshuab hluav taws xob tsis tuaj yeem ua kom haum rau kev sib haum xeeb, ua rau muaj zog teb. Piv txwv li, qee yam titanium - cov khoom siv hlau tuaj yeem muaj txiaj ntsig zoo hauv cov ntawv siv uas muaj zog, xws li hauv qee hom hluav taws xob sib nqus.
- Kev sib txuas nrog cov ntsiab lus tsis yog - sib nqus: thaum titraticitting nrog cov kev coj sib nqus, cov alloy yuav nyob nrog kev txo qis kev sib nqus. Qee cov ntsiab lus xws li txhuas, vanadium, thiab molybdenum yog feem ntau siv hauv titanium alloys. Cov ntsiab no tsis muaj cov khoom sib nqus muaj zog ntawm lawv tus kheej, thiab thaum ntxiv rau cov qauv sib nqus ntawm cov qauv hluav taws xob lossis hloov cov qauv hluav taws xob uas cuam tshuam. Piv txwv li, cov dav siv ti - 6 al {}} v alloy, uas muaj aluminium thiab vanadium, yog paramagnetic. Lub xub ntiag ntawm cov ntsiab lus alloy tsis hloov qhov tag nrho paramagnetic xwm ntawm cov alloy, thiab nws tseem muaj kev cuam tshuam tsis muaj zog nrog cov sib nqus.

Cov ntawv thov thiab txiav txim siab
Cov khoom sib nqus ntawm cov khoom sib nqus ntawm titanium alloys ua si ib lub luag haujlwm tseem ceeb hauv ntau yam kev siv. Hauv kev lag luam hauv Aerospace, qhov chaw uas tsis yog - cov ntaub ntawv sib nqus yog feem ntau nyiam kom tsis txhob cuam tshuam hluav taws xob thiab kev sib nqus typigic {{v yog dav siv. Lawv qhov tsis yog - ferromagnetic xwm kom ntseeg tau tias lawv tsis ua rau cov teb tsis txaus uas tuaj yeem cuam tshuam cov khoom siv ntawm onboard.

Hauv kev kho mob teb, cov khoom sib nqus ntawm cov an titanium alloys kuj tseem ceeb. Piv txwv li, hauv kev tsim ntawm Orthopedic kev cog lus, qhov tsis yog - ferromagnetic xwm ntawm feem ntau titanium alloys tau txais txiaj ntsig. Nws tso cai rau cov neeg mob kom yauv tsis muaj kev sib cav sib ceg (MRI) yam tsis muaj kev cuam tshuam loj thiab muaj peev xwm ua rau cov kev kuaj mob tsis raug.

Hauv kev xaus, cov khoom sib nqus ntawm cov khoom sib nqus ntawm cov khoom siv sib nqus ntawm alloys muaj ntau yam muaj ntau yam thiab nyob ntawm cov ntsiab lus ntawm kev sib cais thiab lawv cov ntau. Thaum ntshiab titanium yog paramagnetic, ntxiv rau ntawm cov sib txawv ntawm cov neeg sib txawv, los ntawm ferromagnetic los yog txawm nrog txo kev sib nqus. Nkag siab cov khoom sib nqus yog qhov tseem ceeb rau kev xaiv cov khoom siv hluav taws xob lossis kev kho mob, lossis cov khoom siv sib nqus rau cov ntawv thov tshwj xeeb engineering.
