titanium puas tuaj yeem ua rau cov hlau ntes?
Hlau ntes, cov cuab yeej tseem ceeb hauv kev kuaj xyuas kev ruaj ntseg, archaeology, thiab kev soj ntsuam kev lag luam, ua haujlwm ntawm lub hauv paus ntsiab lus ntawm electromagnetic induction. Thaum cov khoom siv hlau nkag mus rau qhov sib nqus sib nqus uas tsim los ntawm lub tshuab ntes, cov nyhuv eddy tam sim no ua rau qhov rov qab sib nqus teb, ua rau lub tswb. Lub hauv paus ntsiab lus no hais tias tus ntes qhov rhiab heev rau cov hlau yog nyob ntawm cov khoom siv lub cev, xws li conductivity, magnetic permeability, thiab magnetic susceptibility. Titanium, cov khoom siv tshwj xeeb sib xyaw ua ke nrog lub zog siab thiab biocompatibility, yuav tsum muaj kev tshuaj xyuas zoo ntawm nws cov kev cuam tshuam nrog cov khoom siv hlau, xav txog ob qho tib si cov xwm txheej tshwj xeeb thiab cov khoom siv tus yam ntxwv.
Lub cev muaj zog ntawm titanium ua rau muaj qhov sib txawv tseem ceeb hauv nws cov lus teb rau cov hlau ntes. Txawm hais tias cov ntshiab titanium conductivity tsis muaj zog dua li cov hlau xws li hlau thiab tooj liab, nws tseem siab dua li cov khoom tsis yog- hlau. Nws qhov sib nqus permeability (1.00004) yog ze rau ntawm lub tshuab nqus tsev ib puag ncig, cais nws raws li cov khoom siv tsis zoo. Cov yam ntxwv no txhais tau hais tias titanium tsis muaj zog txaus nyiam rau cov khoom sib nqus xws li ferromagnetic cov ntaub ntawv (xws li cov hlau tsis zoo tib yam) los yog tiv thaiv tag nrho los ntawm kev hloov pauv ntawm magnetic teb. Piv txwv li, titanium alloy porcelain crowns, tsis muaj ferromagnetic Cheebtsam, feem ntau tsis ua rau lub tswb thaum lub sij hawm kuaj hniav; thiab titanium alloy hniav nyiaj hniav kub feem ntau tso cai nyob rau hauv siab - ceev kev tsheb ciav hlau kev ruaj ntseg xyuas vim nws cov ntsiab lus hlau tsawg. Txawm li cas los xij, yog tias cov khoom siv titanium tuab lossis loj (xws li titanium alloy daim hlau), lawv cov khoom siv hluav taws xob tseem tuaj yeem raug kuaj pom los ntawm cov khoom siv, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas cov cuab yeej siv kev ruaj ntseg yog cov rhiab heev.
Kev kho mob cog yog ib qho xwm txheej uas titanium cuam tshuam nrog cov hlau ntes. Kev kho mob titanium alloy cov khoom xws li kev cog hniav hauv tsev menyuam thiab cov pob qij txha, uas yuav tsum tau nyob hauv lub cev ntev - lub sij hawm, yuav tsum tau xaiv cov khoom uas sib npaug biocompatibility thiab electromagnetic compatibility. Niaj hnub nimno kho mob titanium alloys, los ntawm optimized muaj pes tsawg leeg ratios (xws li ntxiv ntawm txhuas thiab vanadium), ntxiv txo magnetization, exhibiting stability nyob rau hauv MRI cov cuab yeej xws li 1.5T mus rau 3.0T, tsis hloov los yog tsim tshav kub vim magnetic teb. Txawm li cas los xij, nyob rau hauv kev ruaj ntseg scenarios, seb qhov kev cog qoob loo no ua rau lub tswb nrov nyob ntawm qhov ntsuas qhov ntsuas thiab qhov tuab ntawm cov titanium alloy: cov khoom siv kev ruaj ntseg hauv tshav dav hlau, uas yuav tsum tau kuaj xyuas cov khoom txaus ntshai xws li riam thiab phom, yog qhov rhiab heev thiab yuav ua rau cov lus teb me ntsis rau cov phaj tuab titanium alloy; thaum lub rooj vag kev ruaj ntseg hauv qhov chaw xws li siab - chaw nres tsheb ciav hlau ceev thiab chav kuaj xyuas tsis tshua muaj kev nkag siab thiab feem ntau tso cai rau titanium alloy hniav nyiaj hniav kub los yog cog me me hla. Txhawm rau kom tsis txhob ncua sijhawm, cov neeg mob tuaj yeem nqa cov ntaub ntawv kho mob uas qhia txog cov khoom siv thiab qhov chaw ntawm qhov cog.
Titanium cov khoom hauv kev lag luam thiab cov neeg siv khoom siv nthuav tawm ntau cov lus teb rau cov hlau ntes. Lub titanium alloy siab-cov plhaub tiv taus siv hauv qhov sib sib zog nqus- hiav txwv sojntsuam, yuav tsum tau tiv taus siab- qhov chaw siab, feem ntau yog 5 hli tuab, thiab lawv cov conductivity tej zaum yuav raug kuaj los ntawm cov cuab yeej rhiab heev. Txawm li cas los xij, lub teeb yuag titanium alloy tsom iav tsom iav, watches, thiab lwm yam khoom nyias, nrog rau lawv cov ntsiab lus hlau qis, tsis tshua muaj kev ceeb toom thaum lub sij hawm kuaj xyuas kev ruaj ntseg. Nws yog ib nqi sau cia hais tias qee cov khoom cuav titanium alloy muaj nyob rau hauv kev ua lag luam, uas tej zaum yuav tov nrog ferromagnetic hlau (xws li npib tsib xee thiab hlau), ua rau lawv cov lus teb tiag tiag txawv ntawm cov ntshiab titanium. Cov neeg siv khoom yuav tsum txheeb xyuas cov ntaub ntawv muaj pes tsawg leeg los ntawm kev tshaj tawm txoj hauv kev thaum yuav cov khoom titanium kom tsis txhob muaj kev ruaj ntseg tsis tsim nyog vim yog impurities.
Qhov tshwm sim ntawm titanium ntawm cov hlau ntes tsis yog qhov tseeb tab sis yog txiav txim siab los ntawm cov khoom siv, cov khoom zoo, thiab cov khoom ntes. Ntshiab titanium thiab titanium alloys, vim lawv cov khoom paramagnetic, feem ntau tsis muaj cov lus teb muaj zog thaum lub sij hawm niaj hnub kuaj xyuas kev ruaj ntseg, tab sis tuab - cov khoom siv phab ntsa lossis cov khoom sib xyaw nrog cov khoom siv ferromagnetic tseem tuaj yeem kuaj pom. Nrog rau kev nce qib hauv cov ntaub ntawv tshawb fawb, cov titanium tshiab, los ntawm kev ua kom zoo tshaj plaws thiab cov qauv tsim, ntxiv txo cov electromagnetic cuam tshuam, ua rau lawv cov kev siv hauv kev kho mob, aerospace, thiab tob - hiav txwv tshawb nrhiav kev nyab xeeb thiab txhim khu kev qha. Rau cov neeg siv niaj hnub, kev nkag siab txog cov khoom siv ntawm cov khoom siv titanium thiab cov qauv kev ua haujlwm ntawm cov cuab yeej tshuaj xyuas kev ruaj ntseg tuaj yeem txo cov kev nkag siab tsis zoo thiab ua kom muaj txiaj ntsig zoo.
