Nitinol ntau npaum li cas
Nitinol nqi dab tsi?
Nitinol, txwv tsis pub hu ua Ni-Ti los yog lub cim xeeb sib xyaw, yog cov khoom siv nickel-titanium uas muaj peev xwm tshwj xeeb los "nco" nws cov duab tshwj xeeb thiab rov qab mus rau nws tom qab raug disfigured. Cov cuab yeej no nyob ntawm nitinol qhov kev txiav txim siab nto moo hauv ntau qhov kev lag luam, suav nrog biomedical, tsheb, aviation, thiab tshuab tshuab. Txawm li cas los xij, tus nqi ntawm nitinol yog nruab nrab siab sib piv nrog cov hlau sib txawv. Peb yuav tshawb xyuas cov teeb meem cuam tshuam nrog kev tsim cov nitinol thiab cov yam ntxwv uas ua rau nws tus nqi siab hauv kab lus no.
Puas yog nitrinol pheej yig?
Tsis yog, nitinol tsis yog me me, thiab cov nuj nqis tuaj yeem hloov pauv raws li tus neeg tsim khoom, tus neeg muab kev pabcuam, thiab ntau yam xws li qhov tsis zoo ntawm cov khoom siv thiab kev sib xyaw ua ke. Tus nqi ntawm nitinol feem ntau siab dua cov hlau sib txawv xws li cov hlau tawv tawv lossis titanium. Nitinol hlau, piv txwv li, tam sim no tus nqi ntawm $ 6 thiab $ 2 ib ko taw ntawm kev ua lag luam, whereas stainless hlau hlau tsuas yog nqi ntawm $ 1 thiab $ 10 ib ko taw.
Vim li cas nitinol thiaj li kim?
Ob peb qhov sib txawv ntxiv rau cov nuj nqis tseem ceeb ntawm nitinol, suav nrog nrog:
1. Unrefined khoom:Nitinolxav tau ib qho kev faib ua feem ntawm npib tsib xee thiab titanium, yog li kev siv tau thiab tus nqi ntawm cov hlau no tuaj yeem cuam tshuam tus nqi ntawm nitinol.
2. Fabricating Cycle: Nitinol yog tsim nyob rau hauv ntau theem, xws li melting, casting, dov, thiab cua sov kho. Cov theem no yog complex. Lub voj voog yuav tsum muaj cov khoom siv tshwj xeeb thiab muaj peev xwm, uas tuaj yeem ntxiv rau cov nuj nqis.
3. Kev Tswj Xyuas Zoo: Nitinol feem ntau siv rau hauv cov ntawv thov tseem ceeb, xws li kev cog lus kho mob, qhov twg cov khoom tsis ua haujlwm tuaj yeem muaj qhov cuam tshuam loj heev. Tom qab ntawd, kev ntsuas kev tswj xyuas kev ua tau zoo yog qhov tseem ceeb, uas tuaj yeem nthuav dav tus nqi.
4. Kev ua haujlwm tshiab: Kev nce qib ntawm cov khoom siv nitinol tshiab thiab cov ntawv thov yuav tsum muaj kev sim ua haujlwm tshiab, uas tuaj yeem ntxiv rau cov nuj nqis dav dav.
Puas yog nitrinol nyuaj ua?
Yog lawm, cov khoom tshwj xeeb ntawm nitinol ua rau nws nyuaj rau ua. Kev sib cuam tshuam suav nrog ob peb theem, suav nrog:
1. Melting: Cov nickel thiab titanium yog softened ua ke hauv lub tshuab nqus tsev vacuum kom ua tiav ib qho kev faib ua feem.
2. Casting: Lub softened ua ke yog projected rau hauv ingots los ntawm khoob nws mus rau hauv ib daim ntawv. Tom qab ntawd cov ingots yog txias thiab ntxuav.
3. Rolling: Cov ingots tau txav mus rau hauv cov ntawv los yog cov xov hlau ntawm qhov zoo tagnrho thickness thiab loj.
4. Kev kho cua sov: Cov nplooj ntawv lossis cov xov hlau tau kho cua sov kom ua tiav cov khoom zoo, zoo li cov duab nco thiab superelasticity.
Txhua theem xav tau cov iav tshwj xeeb thiab muaj peev xwm, thiab kev poob siab txhua lub sijhawm tuaj yeem ua rau deformities lossis irregularities thaum kawg tshwm sim.
Dab tsi yog qhov teeb meem nrog nitinol?
Thaum nitinol muaj ntau yam zoo, nws kuj tseem muaj ob peb qhov tsis zoo uas tuaj yeem muaj teeb meem rau cov neeg tsim khoom thiab cov neeg siv khoom kawg. Piv txwv li:
1. Kev daws teeb meem: Raws li tau hais los saum toj no, nitinol tau sim tsim vim nws cov khoom tshwj xeeb, uas tuaj yeem ua rau muaj kev hloov pauv ntawm qhov tshwm sim.
2. Cov khoom sov sov: Nitinol lub cim xeeb thiab cov khoom siv superelasticity yog qhov kub thiab txias, uas tuaj yeem txwv tsis pub siv rau hauv cov ntawv thov kub.
3. Consumption Opposition: Nitinol yog qhov yooj yim rau yaig nyob rau hauv tej yam kev mob, uas yuav cuam tshuam nws exhibition thiab lub neej ncua.
4. Biocompatibility: Thaum nitinol siv ntau zaus hauv kev siv tshuaj kho mob, cov neeg mob yuav muaj cov lus teb tsis zoo rau cov khoom siv.
Yuav ua li cas ua nitinol
Feem ntau, cov kauj ruam hauv qab no yuav tsum tau ua kom nitinol:
1. Melting: Hauv lub tshuab nqus tsev, cov titanium thiab npib tsib xee yog melted ua ke nyob rau hauv ib qho piv txwv.
2. Casting: Kev sib xyaw ua ke yog ua tiav cov duab los ua ib qho ingot.
3. Rolling: Lub ingot yog txav mus rau hauv cov ntawv los yog cov xov hlau ntawm qhov zoo tagnrho thickness thiab loj.
4. Kev kho cua sov: Cov nplooj ntawv lossis cov xov hlau raug kho cua sov kom ua tiav cov khoom zoo.
5. Fabrication: Cov nplooj ntawv nitinol lossis cov xov hlau tuaj yeem ua haujlwm ntxiv, xws li txiav, sib tw, lossis thav duab, kom ua tiav qhov kawg.
Xaus
Tag nrho hauv tag nrho, thaum nitinol tsis yog me me, nws cov khoom tshwj xeeb mus nrog nws qhov kev txiav txim siab paub zoo hauv ntau qhov kev lag luam. Nitinol tus nqi siab tuaj yeem raug ntaus nqi rau ntau yam, suav nrog cov txheej txheem tsim khoom, kev tswj xyuas zoo, thiab cov khoom siv raw. Kev tsim cov nitinol yog sim vim nws cov khoom tshwj xeeb, uas xav tau cov iav tshwj xeeb thiab kev txawj ntse. Nitinol muaj qee qhov tsis zoo, tab sis nws qhov zoo dua lawv nyob rau ntau qhov xwm txheej. Nrog rau kev ua haujlwm tshiab, nitinol txoj kev siv yog tej zaum yuav loj hlob ntawm no tawm mus.
