Yakareruka Aluminium Alloy Nhare Kumira- Gadzirisa

Nickel-titanium memory wire

Nitinols anoshandiswa zvakanyanya mumidziyo yekurapa, aerospace, midziyo yemagetsi, uye maindasitiri emotokari uye anozivikanwa nemabasa awo akasiyana uye kuita kwakanakisa. Nickel-titanium alloy, inozivikanwawo sememory alloy, inorumbidzwa sekubudirira mune zvesainzi yezvekushandisa nekuda kwekuyeuka kwayo uye superelasticity.

Chekutanga, ndangariro mhedzisiro yenitinol waya inovabvumira kuti vadzoke kune preset chimiro kana ichipisa, chinhu chinonyanya kukosha mumidziyo yekurapa. Semuyenzaniso, mukushandiswa kwemastents emwoyo, nickel-titanium alloy stents inogona kudzvinyirirwa pane tembiricha yakaderera kuti ifambise kuisirwa mumuviri, yobva yadzokera kuchimiro chekutsigira tsinga dzeropa pakupisa kwemuviri, izvo zvinovandudza zvakanyanya budiriro yehuwandu. oparesheni uye kukurumidza kupora kwemurwere.

Chechipiri, iyo superelastic zvimiro zvenickel-titanium alloy waya inogonesa kupora nekukasira mushure mekushanduka pasina deformation zvachose. Ichi chivakwa chinoita kuti chirambe chakasimba uye chakavimbika mune aerospace uye zvemagetsi michina. Kunyanya munzvimbo dzepamusoro-vibration kana dzakakwirira-kudzvanywa, waya yeNiTi inogona kumira yakadzokororwa kutenderera kutenderera pasina kurasikirwa nemidziyo yavo.

Pamusoro pezvo, Nitinol ine biocompatibility yakanaka uye kurwisa ngura, zvichiita kuti ive yakakosha kushandiswa mundima yekurapa. Nitinol wire haigone kungobata biological tissue kwenguva yakareba pasina kurambwa asiwo kuchengetedza kushanda kwakadzikama munzvimbo dzine hunyoro uye dzinoparadza.

Muchidimbu, Nitinol waya, ine yakanakisa ndangariro mhedzisiro, super-elasticity, kusimba, uye biocompatibility, dzave sarudzo dzakanakira dzakasiyana siyana dzinoda maapplication uye dzakasimudzira budiriro uye hunyanzvi hwemaindasitiri mazhinji.

Memory effect

Chimiro chakakosha cheNitinol. Mhedzisiro iyi inobvumira iyo Nitinol chitubu kuti idzokere kune yakafanorongwa chimiro pamusoro peiyo chaiyo Memory maitiro mutembiricha renji. Semuyenzaniso, mukuvhiya kushoma, madhairekitori eNitinol uye stents anogona kuremara pakudziya kwakaderera uye kuiswa nyore nyore mumuviri. Kana tembiricha yemuviri yasvika, zvishandiso izvi zvinodzokera kuchimiro chazvo chepakutanga, zvichipa rutsigiro rwakakodzera kana kutungamira basa, zvakanyanya kuvandudza kurongeka uye kuchengetedzwa kwemaitiro.

hyperelasticity

Nitinol wire inogona kukurumidza kudzokera kumamiriro avo ekutanga mushure mekuremara kwakakura pasina deformation zvachose. Iyi ficha yakakosha munzvimbo dzepamusoro-vibration uye zvakanyanya-kushushikana. Muindasitiri yeaerospace, zvitubu zveNitinol zvinoshandiswa muzvikamu zvakakosha senge injini uye masisitimu ekudzora kuti arambe achidzokororwa kutenderera kutenderera uye kuve nechokwadi chenguva refu yekuvimbika system uye kugadzikana. Mumidziyo yemagetsi, nickel-titanium alloy zvitubu anoshandiswa mune yakakwirira-chaiyo yekubatanidza uye madiki switch kuti ipe kwenguva refu elastic kusimba uye kuve nechokwadi chekushanda kwemidziyo.

Biocompatibility uye corrosion resistance

Nitinol's yakanakisa biocompatibility inoita kuti ive yakanakira zvinhu zvekurapa. Izvo hazvizokonzeri kurambwa kwekudzivirira uye inovimbisa kuchengetedzwa kwekushandiswa kwenguva refu. Nitinol inokwanisawo kuchengetedza michina yayo uye kugadzikana munzvimbo dzine hunyoro uye dzinoparadza uye inoshandiswa zvakanyanya muinjiniya yemugungwa nemidziyo yemakemikari kuve nechokwadi chekushanda kwakavimbika munzvimbo dzakaoma.

Nickel-titanium alloy chitubu munzvimbo dzakasiyana dzekushandisa:

1. Cardiac stent:

Mukuvhiya kwemoyo, Nitinol inoshandiswa kugadzira moyo stents. Iyo stent inogona kuomeswa kusvika padiki diki pane tembiricha yakaderera, ichibvumira kuti iiswe nyore mutsinga dzeropa kuburikidza nekuvhiyiwa kushoma. Kana iyo stent ichipinda mumuviri wemunhu uye ichikanganiswa nekupisa kwemuviri, ndangariro ye nitinol inoita kuti idzokere kune yayo yakatambanudzwa fomu, nekudaro ichitsigira tsinga yeropa uye kuchengetedza tsinga yeropa yakavhurika. Kana ichienzaniswa neyakajairwa simbi stents, nickel-titanium alloy stents anowedzera kuchinjika uye anogona kuchinjika zviri nani kukufamba kwechisikigo kwetsinga uye kuderedza kuitika kwemashure ekuvhiya.

2. Orthodontics:

Nitinol inoshandiswa zvakanyanya mu orthodontics. Iyo nickel-titanium alloy archwire inoshandiswa mukurapa orthodontic inogona kutora mukana wekuyeuka kwayo uye super-elastic zvimiro kuti igadzirise otomatiki chimiro chayo zvichienderana nekushanduka kwetembiricha uye kushandisa inoenderera uye yakapfava kururamisa simba. Ichi chinyorwa chinoratidza kumira kwakanaka kwekuora munzvimbo yemuromo, uye kukwirira kwayo kwepamusoro kunoita kuti varwere vanzwe vakasununguka, inoderedza nguva yekurapa, uye inovandudza kugadzirisa.

3. Kuvhiyiwa kweziso :

Nitinol inoshandiswa mukugadzira intraocular lens suspensions. Panguva yekuvhiyiwa kwecataract, mudziyo unogona kuisirwa muziso uchishandisa maitiro mashoma. Iyo yekurangarira mhedzisiro ye nickel-titanium alloy inobvumira kuti iwedzere kuwedzera uye kugadzirisa lens kana tembiricha yachinja, kuve nechokwadi chekuvhiya kwakaringana uye kwakagadzikana. Iyo biocompatibility yezvinhu inovimbisa kuchengetedzwa kwayo kwenguva refu muziso.

4. Muchadenga :

Mundima yeaerospace, nickel-titanium alloy springs anoshandiswa muzvikamu zvakakosha senge injini dzendege uye masisitimu ekudzora. Nekuda kweNitinol's superelasticity, zvitubu izvi zvinogona kumirisana nepamusoro frequency vibrations uye yakakura deformation apo ichichengetedza zvivakwa zvavo zvepakutanga mushure mekutenderera kwakawanda kwekushushikana. Kuvimbika uku kunonatsiridza zvakanyanya hupenyu hwesevhisi uye kuchengetedzeka kwezvikamu zvendege uye kunoderedza mari yekugadzirisa uye kuderera.

5. Zvigadzirwa zvemagetsi :

Mumidziyo yemagetsi, nitinol zvitubu zvinoshandiswa kugadzira yakakwirira-chaiyo yekubatanidza uye micro switch. Yayo yakanyanya elasticity uye kusimba inovimbisa kuti chinongedzo chinogona kuchengetedza yakagadzikana yekubatanidza kuita pasi pekugara plugging uye unplugging uye yakakwirira-voltage nharaunda. Kunyanya mumafoni emafoni uye zvitubu zvinopfekwa, zvitubu zve nitinol zvinopa tsigiro yakavimbika yemakina uye kubatanidza magetsi, inosimudzira kuita kwese uye kusimba kwechishandiso.

6. Automobile industry :

Zvitubu zveNitinol zvinoshandiswa mumotokari kumiswa masisitimu uye zvikamu zveinjini. Yayo yakakwirira elasticity uye kuneta kuramba inogonesa mota kuti inyatso kubata vibrations panguva yekutyaira, kuvandudza kunakidzwa kwekukwira uye kutyaira kuchengetedza. Panguva imwecheteyo, Nitinol's corrosion resistance inovimbisa kugadzikana kwenguva refu kwezvikamu izvi munzvimbo dzakasiyana-siyana dzakaoma uye inowedzera hupenyu hwebasa remotokari.
