Neodymium Iron Boron Magnets nimwe mumasoko akomeye yubucuruzi ahoraho aboneka uyumunsi. Izi magneti zidasanzwe zisi zirashobora gukomera inshuro 10 kurenza magnetique ceramic ikomeye. Ububiko bwa NdFeB busanzwe bukorwa hifashishijwe kimwe mubice bibiri byuburyo rusange, magneti ahujwe (compression, inshinge, extrusion cyangwa kalendari molding), hamwe na magneti yacumuye (ifu ya metallurgie, inzira ya PM). Magnet ya NdFeB ikoreshwa mubicuruzwa bisaba magnesi zihoraho nka disiki ikomeye ya mudasobwa, moteri yamashanyarazi mubikoresho bitagira umugozi, hamwe na feri. Kubikoresho byubuvuzi porogaramu nshya ikoreshwa rya magnesi zikomeye ziragaragara. Kurugero, kugendana catheter, aho magnesi zishobora kwinjizwa mumutwe winteko ya catheter kandi ikagenzurwa na sisitemu yo hanze ya magnetiki yo kuyobora no gutandukanya ubushobozi.
Ubundi buryo bukoreshwa mubuvuzi burimo kwinjiza imashini ifungura magnetiki resonance yerekana amashusho (MRI) ikoreshwa mugushushanya no gushushanya anatomiya, nkubundi buryo bwa magneti arenze urugero busanzwe bukoresha ibishishwa byinsinga kugirango bibyare umurima wa rukuruzi. Ibindi byifashishwa mubikoresho byubuvuzi birimo, birebire kandi bigufi byatewe, hamwe nibikoresho byibasiye. Bimwe mubishobora kwibasirwa na neodymium fer boron magnet ni inteko ya endoskopi yinteko zitabarika zirimo; gastroesophageal, gastrointestinal, skeleton, imitsi hamwe ningingo, umutima-mitsi, na neural.
Magnite ya Ferrite, magnesi ya neodymium cyangwa se na magnetiki base ikoreshwa muburyo butandukanye muburyo bwikoranabuhanga, mu nganda ndetse no mubuvuzi. Harakenewe gutanga magnesi hamwe nubuso burinda ruswa, "coating" ya magnesi. Gushyira magneti ya neodymium ninzira yingenzi yo kurinda magneti kwangirika. Substrate NdFeB (Neodymium, Iron, Boron) izahinduka okiside vuba idafite urwego rukingira. Hasi nurutonde rwibisahani / ibishishwa hamwe namababa yabyo kugirango ubone.

Igicapo cya NiCuNi: Igikuta cya nikel kigizwe nibice bitatu, nikel-umuringa-nikel. Ubu bwoko bwo gutwikira ni bwo bukoreshwa cyane kandi butanga uburinzi bwo kwangirika kwa rukuruzi mu bihe byo hanze. Amafaranga yo gutunganya ni make. Ubushyuhe ntarengwa bwo gukora ni hafi 220-240ºC (ukurikije ubushyuhe ntarengwa bwo gukora bwa magneti). Ubu bwoko bwo gutwikira bukoreshwa muri moteri, generator, ibikoresho byubuvuzi, sensor, porogaramu zikoresha amamodoka, kugumana, uburyo bwo kubika firime yoroheje na pompe.
Nikel y'umukara: Imiterere yiyi kote isa niy'ikoti rya nikel, hamwe no gutandukanya ko habaho inzira yinyongera, inteko ya nikel yirabura. Ibyiza bisa nibisanzwe bya nikel; hamwe numwihariko ko iyi coating ikoreshwa mubisabwa bisaba ko ibintu bigaragara mubice bitagaragara.
Zahabu: Ubu bwoko bwo gutwikira bukoreshwa kenshi mubuvuzi kandi buranakwiriye gukoreshwa muguhuza umubiri wumuntu. Hano hari icyemezo cyatanzwe na FDA (Ubuyobozi bushinzwe ibiryo n'ibiyobyabwenge). Munsi ya zahabu hari sub-layer ya Ni-Cu-Ni. Ubushyuhe ntarengwa bwo gukora nabwo bugera kuri 200 ° C. Usibye urwego rwubuvuzi, isahani ya zahabu ikoreshwa no mu mitako no gushushanya.
Zinc: Niba ubushyuhe ntarengwa bwo gukora buri munsi ya 120 ° C, ubu bwoko bwo gutwikira burahagije. Ibiciro biri hasi kandi rukuruzi irinzwe kwangirika mukirere. Irashobora kwizirika ku byuma, nubwo igomba gukoreshwa idasanzwe. Ipitingi ya zinc irakwiriye mugihe inzitizi zo gukingira rukuruzi ziri hasi kandi ubushyuhe buke bwakazi bwiganje.
Parylene: Iyi coating nayo yemejwe na FDA. Kubwibyo, zikoreshwa mubikorwa byubuvuzi mumubiri wumuntu. Ubushyuhe ntarengwa bwo gukora bugera kuri 150 ° C. Imiterere ya molekile igizwe na hydrocarubone imeze nk'impeta igizwe na H, Cl na F. Ukurikije imiterere ya molekile, ubwoko butandukanye buratandukanye nka: Parylene N, Parylene C, Parylene D na Parylene HT.
Epoxy: Igifuniko gitanga inzitizi nziza irwanya umunyu n'amazi. Hano haribintu byiza cyane bifatanye nicyuma, niba magnet yometse hamwe nudusimba twihariye dukwiranye na magnesi. Ubushyuhe ntarengwa bwo gukora ni hafi 150 ° C. Ububiko bwa epoxy busanzwe bwirabura, ariko burashobora no kuba umweru. Ibisabwa birashobora kuboneka murwego rwamazi, moteri, sensor, ibicuruzwa byabaguzi nu rwego rwimodoka.
Magnets yatewe muri plastiki: cyangwa nanone yitwa kurenza urugero. Ikintu nyamukuru kiranga ni uburyo bwiza bwo kurinda magneti kutavunika, ingaruka no kwangirika. Igice kirinda umutekano kirinda amazi n'umunyu. Ubushyuhe ntarengwa bwo gukora buterwa na plastiki yakoreshejwe (acrylonitrile-butadiene-styrene).
Yakozwe PTFE (Teflon): Kimwe no gutera inshinge / plastike nayo itanga uburinzi buhebuje bwa rukuruzi kugirango itangirika, ingaruka no kwangirika. Magneti irinzwe kubushuhe, amazi n'umunyu. Ubushyuhe ntarengwa bwo gukora buri hafi 250 ° C. Iyi coating ikoreshwa cyane cyane mubikorwa byubuvuzi no mubiribwa.
Rubber: Igikoresho cya reberi kirinda neza kumeneka n'ingaruka kandi bigabanya ruswa. Ibikoresho bya reberi bitanga imbaraga zo kunyerera hejuru yicyuma. Ubushyuhe ntarengwa bwo gukora buri hagati ya 80-100 ° C. Magneti yinkono hamwe na reberi ni ibicuruzwa bigaragara kandi bikoreshwa cyane.
Duha abakiriya bacu inama zumwuga nibisubizo byuburyo bwo kurinda magnesi yawe no kubona uburyo bwiza bwa magneti. Twandikire natwe tuzishimira gusubiza ikibazo cyawe.
