Ferrite / Ceramic
Va'aiga lautele:
Maneta ferrite tumau, lea e lauiloa foi o le maneta malosi, o se mea e le-metallic maneta material.In 1930, Kato ma Wujing maua se ituaiga o spinel (MgA12O4) maneta tumau, o le prototype o ferrite faaaogaina lautele today.Ferrite maneta e tele lava faia. o le SrO poʻo le Bao ma le Fe2O3 e fai ma mea mata e ala i le sima (muamua fana, tuʻimomomoina, pulverizing, oomi, sintering ma olo).O loʻo i ai uiga o le lautele hysteresis loop, maualuga faʻamalosi malosi ma maualuga remanence.O se ituaiga o mea aoga e mafai ona taofia le maneta faifai pea pe a maneta.O lona mamafa e 4.8g/cm3.E tusa ai ma faiga eseese gaosiga, ferrite maneta e mafai ona vaevaeina i ni ituaiga se lua: sintering ma fusi.Sintering e mafai ona vaevaeina i le oomi mago ma susu oomi, ma e mafai ona vaevaeina le fusia i extrusion, compression ma tui tui.O le maneta vaivai, mausi ma mimilo e faia i le pa'u ferrite fusifusia ma le pa'u gaosia e ta'ua foi o le maneta pa'u.E tusa ai pe faʻaaogaina le maneta fafo pe leai, e mafai ona vaevaeina i le isotropic maneta tumau ma anisotropic maneta tumau.
Faatusatusa i isi mea maneta
Fa'amanuiaga: Tau maualalo, fa'apogai lautele o mea mata'utia, maualuga le vevela (e o'o atu i le 250 ℃) ma le fa'afefe.
Fa'aletonu: Fa'atusatusa i oloa NdFeB, o lona fa'atumauina e matua maualalo lava.E le gata i lea, ona o le maʻaleʻale ma le maaleale o le fausaga o ana mea maualalo, o le tele o auala e faʻaogaina ai e faʻatapulaʻaina, e pei o le tuʻiina, eli, ma isi mea, o le tele o foliga o oloa e mafai ona faʻapipiʻiina e le limu, o le oloa. e le lelei le sa'o o le faapalepale, ma e maualuga le tau o le limu.
Ufiufi: Ona o lona tetee sili ona leaga, e le manaʻomia le puipuiga o le ufiufi.
Samarium cobalt
Samarium cobalt maneta o se ituaiga o maneta eleele seasea.O se ituaiga mea maneta meafaigaluega e faia i le samarium, cobalt ma isi uʻamea mea eleelea e le masani ai e ala i le faʻatusatusa, faʻafefeteina i mea faʻapipiʻi, tuʻimomomoina, oomi ma sintering.O lo'o i ai le maualuga o le malosi fa'amageta oloa ma matua maualalo le vevela coefficient.Ole maualuga ole vevela ole galuega e mafai ona oʻo ile 350 ℃, ma le vevela le lelei e le faʻatapulaʻaina.A oʻo atu le vevela galue i luga aʻe o le 180 ℃, o le maualuga o le gaosiga o le malosi maneta (BHmax) ma le faʻamalosi (co O le mautu o le vevela ma le mautu vailaʻau e maualuga atu nai lo NdFeB.
Alnico
Al Ni Co o se u'amea e aofia ai le alumini, nickel, cobalt, iron ma isi elemene elemene.O loʻo i ai le maualuga o le toe faʻaleleia, maualalo le faʻamalosi, lelei le faʻafefeteina, maualalo le vevela coefficient, maualuga le vevela o le vevela, faʻafefeteina o le susu, malosi faʻafefete, e le faigofie ona faʻamaʻi ma lelei le mautu o galuega.Sintered al Ni Co e gaosia e le pa'u u'amea.E faʻaaogaina lautele i vaega taʻavale, meafaifaʻaili, afi, electroacoustic, fesoʻotaʻiga, kilia magnetoelectric, masini, aʻoaʻoga ma le aerospace.
Maneta Pa'a Fe'avea'i
O maneta fe'avea'i e tutusa lelei ma maneta ua fa'a tui ae e gaosia i fasipepa ma pepa.O nei maneta e maualalo i le malosi maneta ma e matua fetuutuunai e faalagolago i mea na faʻaaogaina i totonu o le faʻaogaina ma le pauta maneta.Vinyl e masani ona faʻaaogaina i lenei ituaiga maneta e fai ma fusi.
