Momwe Ma Magnet Coating Amakhudzira Magwiridwe A Ma Magnet a U Shaped Neodymium

Maginito a neodymium okhala ndi mawonekedwe a U amapereka mphamvu yapamwamba kwambiri ya maginito, koma amakumananso ndi zofooka zapadera chifukwa cha mawonekedwe awo komanso kuthekera kwa dzimbiri kwa zinthu za neodymium. Ngakhale kuti maziko a alloy amapanga mphamvu ya maginito, chophimbacho ndi gawo lofunika kwambiri loteteza, lomwe limatsimikizira mwachindunji magwiridwe antchito ake, chitetezo chake komanso nthawi yogwirira ntchito. Kunyalanyaza kusankha chophimbacho kungayambitse kulephera msanga, kuchepa kwa mphamvu kapena kusweka koopsa.

Udindo Wofunika Kwambiri wa Zophimba
Maginito a Neodymium amawonongeka mofulumira akakumana ndi chinyezi, chinyezi, mchere kapena mankhwala, zomwe zimapangitsa kuti mphamvu ya maginito isasinthe komanso kuti kapangidwe kake kakhale kolimba. Kapangidwe ka mawonekedwe a U kamawonjezera zoopsa izi: kupindika kwake kwamkati kumakhudza kupsinjika kwa makina, mawonekedwe ake ofooka amasunga zodetsa, ndipo ma curve ake ovuta amayesa kufanana kwa utoto. Popanda chitetezo champhamvu, dzimbiri lingayambe kupindika kwamkati, kuwononga mphamvu ya maginito ndikuyambitsa ming'alu yomwe ingayambitse maginito kusweka.

Zophimba Sizingoteteza Kudzimbiri
Zophimba zogwira mtima zimagwira ntchito ngati zotchinga zingapo zoteteza: zimapanga chotchinga chakuthupi ku zoopsa zachilengedwe, zimawonjezera kukana kukanda ndi kusweka pogwira ntchito, zimapereka chitetezo chamagetsi kwa ma mota/ma sensa, komanso zimasunga kumatirira pansi pa kutentha. Kuphimba kozama kwa ngodya ndikofunikira kwambiri pa maginito ooneka ngati U—mipata iliyonse idzafulumizitsa kuwonongeka kwa magwiridwe antchito m'malo omwe ali ndi nkhawa kwambiri.

Kuyerekeza kwa Zosankha Zovala Zofala
Kuphimba kwa Nickel-Copper-Nickel (Ni-Cu-Ni) ndikotsika mtengo ndipo kumapereka chitetezo chabwino komanso kukana kuwonongeka, koma pali chiopsezo cha ma porosity ang'onoang'ono komanso kuphimba kosagwirizana mu U-bend, kotero ndikoyenera kwambiri kugwiritsa ntchito mkati mouma.
Zophimba za epoxy zimapambana kwambiri m'malo ovuta—zophimba zawo zokhuthala komanso zamadzimadzi zimalowa mkati mwa khola, zomwe zimapangitsa kuti chinyezi/mankhwala azigwira bwino ntchito komanso kuti magetsi aziteteza, koma sizimakanda.
Parylene imapereka mamolekyulu obisika opanda mabowo ngakhale m'mipata yozama, zomwe zimapangitsa kuti ikhale yoyenera kwambiri pazochitika zoopsa (zachipatala, zamlengalenga), koma chitetezo chake chamakina ndi chochepa ndipo mtengo wake ndi wokwera.
Zinc ingagwiritsidwe ntchito ngati gawo lofunika kwambiri m'malo ofatsa kumene ndi yotsika mtengo, koma siikhala yolimba kwa nthawi yayitali.
Golide amatsimikizira kuti zinthu zamagetsi zamagetsi sizingagwere komanso kuti zinthuzo zisamayende bwino, koma amafunika kugwiritsidwa ntchito limodzi ndi nikeli kuti athandizire kapangidwe kake.

Zotsatira za Kusankha Kuphimba pa Magwiridwe Abwino
Zophimba zimatsimikiza mwachindunji kukhazikika kwa maginito—kudzikundikira kumachepetsa mphamvu ya Gauss ndi kukoka kwamuyaya. Zimalamulira kulimba kwa kapangidwe kake mwa kupewa ming'alu m'mapiko amkati osaphimbidwa. Zimateteza chitetezo mwa kuletsa zidutswa zofooka. Kuchokera pamagetsi, zophimba zimaletsa ma circuits afupi (epoxy/parylene) kapena zimathandizira kuyenda kwa magetsi (nickel/golide). Chofunika kwambiri, zophimba zosafanana zimalephera m'malo ovuta: maginito okhazikika a U-shaped nickel-plated amawonongeka mwachangu m'malo onyowa, pomwe maginito osaphimbidwa amatha kusokoneza zamagetsi apafupi.

Kusankha Chophimba Chabwino Kwambiri: Mfundo Zofunika Kuziganizira
Ikani patsogolo malo anu ogwirira ntchito: kuwunika chinyezi, kusinthasintha kwa kutentha, kuwonetsa mankhwala, ndi kugwiritsa ntchito mkati/kunja. Dziwani nthawi yofunikira yogwiritsira ntchito—mikhalidwe yovuta imafuna zokutira za epoxy kapena parylene. Dziwani zosowa zamagetsi: kutchinjiriza kumafuna zokutira za epoxy/parylene; conductivity imafuna zokutira za nickel/golide. Yesani momwe makina amagwirira ntchito: zokutira za nickel zimapirira kuvala kuposa zokutira zofewa za epoxy. Nthawi zonse gogomezerani zamkati zomwe zimapindika—ogulitsa ayenera kutsimikizira kufanana m'derali kudzera munjira zapadera. Kulinganiza ndalama ndi zoopsa: Njira zodzitetezera zosakwanira zingayambitse kulephera kokwera mtengo. Pa ntchito zofunika kwambiri, pemphani kuyesa kupopera mchere

Chitani njira zabwino kwambiri
Fotokozani momveka bwino mtundu wa chophimba ndi makulidwe ochepa muzofotokozera (monga, “30μm epoxy”). Funsani opanga kuti apereke umboni wolembedwa wa chophimba chozungulira. Gwirani ntchito ndi akatswiri odziwa bwino ntchito za maginito ooneka ngati U—njira zawo zophikira zimayesedwa kuti zigwirizane ndi mawonekedwe ovuta. Yesani zitsanzo zenizeni musanayambe kupanga zonse; ziwonetseni ku kutentha, mankhwala, kapena chinyezi kuti muwonetsetse kuti zikugwira ntchito bwino.

Kutsiliza: Zophimba ngati Alonda Anzeru
Pa maginito a neodymium okhala ndi mawonekedwe a U, zokutira si mankhwala ochizira pamwamba, koma ndi chitetezo chofunikira kwambiri kuti chikhale chodalirika. Kusankha zokutira za epoxy m'malo onyowa, zokutira za parylene kuti zigwiritsidwe ntchito bwino pa opaleshoni, kapena zokutira zopangira ma plating kuti zigwire ntchito bwino zimatha kusintha kufooka kukhala kulimba. Mwa kufananiza magwiridwe antchito a zokutira ndi zosowa za ntchito ndikutsimikizira chitetezo pamalo opindika kwambiri, mutha kuwonetsetsa kuti magwiridwe antchito apamwamba a maginito kwa zaka zambiri. Musamavutike ndi chitetezo cha zokutira: mphamvu yanu ya maginito imadalira pa izi.
