Ferrite / Ceramic
Isishwankathelo:
Imagnethi esisigxina yeferrite, ekwabizwa ngokuba yimagnethi enzima, yinto engeyiyo eyentsimbi.Ngo-1930, uKato noWujing bafumanisa uhlobo lwemagnethi esisigxina (MgA12O4) yi-prototype yeferrite esetyenziswa ngokubanzi namhlanje.Imagnethi yeFerrite yenziwa ikakhulu. ye-SrO okanye i-Bao kunye ne-Fe2O3 njengemathiriyeli ekrwada ngenkqubo ye-ceramic (ukudubula kwangaphambili, ukutyunyuzwa, ukucolwa, ukucofa, ukutshiza kunye nokusila).Uneempawu ze-hysteresis loop ebanzi, amandla okunyanzeliswa okuphezulu kunye nokugcinwa okuphezulu.Luhlobo lwemathiriyeli esebenzayo enokugcina imazibuthe engaguqukiyo xa sele yenziwe uzibuthe.Ubuninzi bayo yi-4.8g/cm3.Ngokweenkqubo ezahlukeneyo zemveliso, imagnethi ye-ferrite inokwahlulwa ibe ziindidi ezimbini: i-sintering kunye ne-bonding.I-Sintering inokohlulwa ibe yingcinezelo eyomileyo kunye nokucinezela okumanzi, kwaye i-bonding inokwahlulwa ibe yi-extrusion, i-compression kunye ne-injection molding.Imagnethi ethambileyo, enelastiki kunye nejijekileyo eyenziwe ngomgubo weferrite ebotshiweyo kunye nerabha yokwenziwa ikwabizwa ngokuba yimagnethi yerabha.Ngokubhekiselele ekubeni intsimi yangaphandle yamagnetic isetyenziswa okanye hayi, inokwahlulwa ibe yimagnethi esisigxina ye-isotropic kunye nemagnethi esisigxina ye-anisotropic.
Thelekisa nezinye izixhobo zemagnethi
Inzuzo: Ixabiso eliphantsi, umthombo obanzi wezinto eziluhlaza, ukumelana nobushushu obuphezulu (ukuya kuthi ga kwi-250 ℃) kunye nokuxhathisa ukubola.
Ukusilela: Xa kuthelekiswa neemveliso ze-NdFeB, ukuhlala kwayo kuphantsi kakhulu.Ukongeza, ngenxa yesakhiwo esithambileyo kunye nesithambileyo sezinto ezixineneyo eziphantsi, iindlela ezininzi zokucutshungulwa zikhawulelwe yiyo, njengokugqobhoza, ukugrumba, njl. njl., uninzi lwemilo yayo yemveliso inokucinezelwa kuphela ngundo, imveliso. ukunyamezela ukuchaneka kumbi, kwaye ixabiso lokungunda liphezulu.
Ukwaleka: Ngenxa yokumelana nokugqwesa okugqwesileyo, ayifuni ukukhuselwa kokugquma.
iSamarium cobalt
Umazibuthe weSamarium cobalt luhlobo lwemagnethi yomhlaba enqabileyo.Luhlobo lwesixhobo semagnethi esenziwe ngesamarium, cobalt kunye nezinye izinto zentsimbi ezinqabileyo zomhlaba ngomlinganiselo, ukunyibilika kwi-alloy, ukutyumza, ukucinezela kunye nokuntywila.Inemveliso yamandla emagnethi ephezulu kunye neqondo lobushushu elisezantsi kakhulu.Ubushushu obuphezulu bokusebenza bunokufikelela kwi-350 ℃, kwaye iqondo lobushushu elibi alinamda.Xa ubushushu bokusebenza bungaphezulu kwe-180 ℃, imveliso yayo ephezulu yamandla kazibuthe (BHmax) kunye nokunyanzeliswa (co Ukuzinza kweqondo lokushisa kunye nokuzinza kweekhemikhali ziphezulu kunezo ze-NdFeB.
Alnico
I-Al Ni Co yi-alloy eyenziwe nge-aluminiyam, i-nickel, i-cobalt, i-iron kunye nezinye izinto zentsimbi.Ine-remanence ephezulu, ukunyanzeliswa okuphantsi, ukuxhathisa okulungileyo kwe-corrosion, i-coefficient yobushushu obuphantsi, ukuxhathisa ubushushu obuphezulu, ukuxhathisa ukufuma, ukuxhathisa okuqinileyo kwe-corrosion, akukho lula ukwenza i-oxidize kunye nokuzinza okulungileyo kokusebenza.I-Sintered al Ni Co iveliswa ngumgubo wesinyithi.Isetyenziswa ngokubanzi kwiindawo zeemoto, izixhobo, iimoto, i-electroacoustic, unxibelelwano, iswitshi yemagnetoelectric, inzwa, imfundiso kunye ne-aerospace.
I-Flexible Rubber Magnet
Iimagnethi eziguquguqukayo ziyafana kakhulu neemagnethi ezibunjiweyo zenaliti kodwa ziveliswa ngemicu kunye namashiti.Ezi magnethi zisezantsi kumandla kazibuthe kwaye zibhetyebhetye kakhulu ngokuxhomekeke kwizinto ezazisetyenziswa kwikhompawundi kunye nomgubo wemagnethi.IVinyl isoloko isetyenziswa kolu hlobo lwemagnethi njengesibophelelo.
