Waya/Mzere/Ndodo ya Mu 49 (FeNi50) Wofewa wa Magnetic Alloy

Aloyi yachitsulo yofewa ya nickel yokhala ndi maziko a nickel yachitsulo yokhala ndi Co, Cr, Cu, Mo, V, Ti, Al, Nb, Mn, Si ndi zinthu zina za aloyi, ndiye aloyi yachitsulo yosinthasintha kwambiri, mtundu wa mitundu yambiri ndi mafotokozedwe, mlingo pambuyo pa pepala lachitsulo la silicon ndi chitsulo choyera chamagetsi. Poyerekeza ndi aloyi ena ofewa a maginito, aloyi yomwe ili mu gawo la geomagnetic ili ndi mphamvu yayikulu ya maginito komanso mphamvu yochepa yokakamiza, aloyi ena ali ndi rectangular hysteresis loop, kapena mphamvu yotsika kwambiri ya maginito yotsalira komanso mawonekedwe okhazikika a maginito ndipo ali ndi cholinga chapadera.
Mtundu uwu wa aloyi uli ndi mphamvu zabwino zotsutsana ndi dzimbiri komanso mphamvu zokonzera, mawonekedwe ndi kukula kwake zimatha kupangidwa kukhala zigawo zolondola kwambiri. Chifukwa mphamvu ya aloyi ndi yokwera kuposa chitsulo choyera ndi pepala lachitsulo la silicon, ndipo imakonzedwa mosavuta kukhala lamba woonda, kotero kuti pansi pa lamba woonda wa microns ochepa, ikani pa MHZ yochepa pafupipafupi.
Mphamvu yokhuta ya maginito yolowetsedwa ndi kutentha kwa Curie kwa aloyi ndi yokwera kuposa zida zofewa zamaginito za ferrite, mumakampani opanga ndege ndi mafakitale ena amagetsi kuti apange kukhudzidwa kwakukulu, kulondola kwa kukula, voliyumu yaying'ono, kutayika kochepa pafupipafupi, kukhazikika kwa nthawi ndi kutentha komanso kugwira ntchito kwa zida zapadera zamagetsi. Mu kulumikizana, zida, makompyuta amagetsi, kulamulira kutali, kuzindikira kutali ndi zina zotero zimagwiritsidwa ntchito kwambiri mu dongosololi.

Aloyi ofewa a maginito ali mu mphamvu yofooka ya maginito yokhala ndi mphamvu zambiri zolowera komanso mphamvu zochepa zokakamiza za aloyi. Mtundu uwu wa aloyi umagwiritsidwa ntchito kwambiri mu zamagetsi a wailesi, zida zolondola ndi zoyezera, zowongolera kutali ndi makina owongolera okha, kuphatikiza kumeneku kumagwiritsidwa ntchito makamaka posintha mphamvu ndi kukonza chidziwitso, mbali ziwirizi ndizofunikira kwambiri pachuma cha dziko.

Chiyambi
Mphamvu yakunja ya maginito yofewa ya aloyi ya maginito imachepa pang'onopang'ono pambuyo poti mphamvu ya maginito ya induction ndi maginito yachotsedwa.
Malo ozungulira a hysteresis ndi ang'onoang'ono komanso opapatiza, mphamvu yokakamiza nthawi zambiri imakhala pansi pa 800 a/m, kukana kwakukulu, kutayika kwa eddy current ndi kochepa, kutseguka kwakukulu, kulowetsedwa kwa maginito okwera kwambiri. Nthawi zambiri amakonzedwa kukhala mapepala ndi mzere. Kusungunuka kunakonzedwa. Amagwiritsidwa ntchito makamaka pazida zamagetsi, makampani olumikizirana m'magawo osiyanasiyana apakati (monga transformer core, relay iron core, choke coil, ndi zina zotero). Aloyi yofewa yamaginito yomwe imagwiritsidwa ntchito nthawi zambiri imakhala ndi chitsulo chamagetsi chotsika mpweya, chitsulo cha eminem, pepala lachitsulo la silicon, aloyi yofewa yamaginito, chitsulo, aloyi yofewa yamaginito ya cobalt, chitsulo cha nickel chitsulo cha silicon soft magnetic alloy, ndi zina zotero.

Pansi pa mphamvu ya maginito yakunja mosavuta pambuyo pa maginito, kupatula mphamvu ya maginito yolowetsa mphamvu (maginito) ndi kutha kwa aloyi ya maginito. Malo ozungulira a Hysteresis ndi ang'onoang'ono komanso opapatiza, mphamvu yokakamiza (Hc) pafupifupi yochepera 10 Oe (onani aloyi yolondola). Kumapeto kwa zaka za m'ma 1800 yopangidwa ndi injini yachitsulo chotsika cha kaboni ndi pakati pa transformer. 1900 pepala lachitsulo la silicon lapamwamba kwambiri linasintha mwachangu chitsulo chotsika cha kaboni, chomwe chimagwiritsidwa ntchito popanga zinthu zamagetsi zamagetsi. Mu 1917 aloyi ya Ni-Fe kuti igwirizane ndi zosowa zamakono za dongosolo la mafoni. Kenako aloyi ya Fe-Co yokhala ndi mphamvu zosiyanasiyana zamaginito (1929), aloyi ya Fe-Si-Al (1936) ndi aloyi ya Fe-Al (1950) kuti ikwaniritse cholinga chapadera. Mu 1953 China idayamba kupanga pepala lachitsulo la silicon lotentha. Kumapeto kwa zaka za m'ma 50 ndikuyamba kuphunzira aloyi ya Ni-Fe ndi aloyi yofewa yamaginito monga Fe, Co, pang'onopang'ono 60s idayamba kupanga zina mwa aloyi akuluakulu ofewa amaginito. Mu 70s kupanga aloyi yozizira yozungulira lamba wachitsulo cha silikoni.
Mphamvu ya maginito ya aloyi yofewa ya maginito makamaka ndi iyi: (1) mphamvu yokakamiza (Hc) ndi kutayika kochepa kwa hysteresis (Wh); (2) kukana (rho) ndikokwera, kutayika kochepa kwa eddy current (We); (3) kulowerera koyambirira (mu 0) ndi kukwera kwakukulu.

Mitundu ikuluikulu ya
Zingagawidwe m'magulu a chitsulo chamagetsi chotsika mpweya ndi chitsulo cha eminem, pepala lachitsulo la silicon, chitsulo cha nickel chofewa cha maginito, chitsulo, cobalt chofewa cha maginito, chitsulo, silicon aluminiyamu chofewa cha maginito, ndi zina zotero. Ponena za mafakitale amagetsi, amagwiritsidwa ntchito makamaka m'munda wamaginito wokhala ndi maginito ambiri komanso kutayika kochepa kwa aloyi. Mumakampani amagetsi, amagwiritsidwa ntchito makamaka m'munda wamaginito wotsika kapena wapakatikati wokhala ndi mphamvu zambiri komanso mphamvu zochepa za aloyi. Pafupipafupi kwambiri, mzere woonda kapena wotsutsa kwambiri wa aloyi uyenera kugwiritsidwa ntchito. Mapepala kapena mzerewu umagwiritsidwa ntchito nthawi zambiri.
