Kugeza ubu, ibikoresho bisanzwe bya magnetiki bihoraho ni ferrite magnet,NdFeb, Imashini ya SmCo, Alnico magnet, rubber magnet nibindi.Ibi biroroshye kugura, hamwe nibikorwa bisanzwe (ntabwo byanze bikunze ibipimo bya ISO) guhitamo.Buri kimwe muri magnesi zavuzwe haruguru gifite imiterere yacyo hamwe nimirima itandukanye ikoreshwa, muri make yatangijwe nuburyo bukurikira.
Imashini ya Neodymium
NdFeb ni rukuruzi ikoreshwa cyane kandi igatera imbere byihuse.
Imashini ya Neodymium ikoreshwa cyane kuva ivumburwa kugeza ubu, ariko kandi imyaka irenga 20.Bitewe na magnetique yo hejuru hamwe no gutunganya byoroshye, kandi igiciro ntabwo kiri hejuru cyane, umurima wo gusaba uraguka vuba.Kugeza ubu, NdFeb yubucuruzi, ibicuruzwa byayo bikoresha ingufu za magneti birashobora kugera kuri 50MGOe, kandi ni inshuro 10 za ferrite.
NdFeb nayo ni ifu ya metallurgie yifu kandi itunganywa muburyo busa na samarium cobalt magnet.
Kugeza ubu, ubushyuhe bwo hejuru bwa NdFeb buri hafi dogere selisiyusi 180.Kubisabwa bikaze, mubisanzwe birasabwa kutarenza dogere selisiyusi 140.
NdFeb yangiritse byoroshye.Kubwibyo, ibyinshi mubicuruzwa byarangiye bigomba guhindurwa amashanyarazi cyangwa gutwikirwa.Ubuvuzi busanzwe burimo isahani ya nikel (nikel-umuringa nikel), isahani ya zinc, isahani ya aluminium, electrophorei, nibindi. Niba ukorera ahantu hafunze, urashobora kandi gukoresha fosifati.
Bitewe na magnetique yo hejuru ya NdFeb, mubihe byinshi, ikoreshwa mugusimbuza ibindi bikoresho bya magneti kugirango igabanye ibicuruzwa.Niba ukoresha magnite ferrite, ubunini bwa terefone igendanwa, mfite ubwoba ko butarenze igice cyamatafari.
Imashini ebyiri zavuzwe haruguru zifite imikorere myiza yo gutunganya.Kubwibyo, kwihanganira ibipimo byibicuruzwa nibyiza cyane kuruta ibya ferrite.Kubicuruzwa rusange, kwihanganira birashobora kuba (+/-) 0.05mm.
Samarium Cobalt
Magari ya Samarium cobalt, ibyingenzi byingenzi ni samarium na cobalt.Kuberako igiciro cyibikoresho gihenze, samarium cobalt magnet ni bumwe muburyo buhenze.
Imbaraga za rukuruzi za samarium cobalt magnet zirashobora kugera kuri 30MGOe cyangwa irenga.Byongeye kandi, samarium cobalt magnet ifite imbaraga nyinshi kandi zihanganira ubushyuhe bwinshi, kandi irashobora gukoreshwa mubushyuhe bugera kuri dogere selisiyusi 350.Kugirango bidasimburwa mubisabwa byinshi
Magari ya Samarium cobalt ni iy'ibicuruzwa byifu.Inganda rusange ukurikije ubunini nuburyo imiterere yibicuruzwa byarangiye bikenerwa, bigatwikwa mu buso bwuzuye, hanyuma ugakoresha icyuma cya diyama kugirango ugabanye ubunini bwibicuruzwa byarangiye.Kuberako samarium cobalt ikoresha amashanyarazi, irashobora gukata umurongo.Mubyukuri, camalt ya samariyumu irashobora gucibwa muburyo bushobora gucibwa umurongo, niba magnetisation nubunini bunini bidafatwa.
Imashini ya Samarium cobalt ifite imbaraga zo kurwanya ruswa kandi mubisanzwe ntisaba isahani yo kurwanya ruswa.Byongeye kandi, samarium cobalt magnette iroroshye, biragoye gukora ibicuruzwa mubunini cyangwa kurukuta ruto.
Alnico magnet
Alnico magnet ifite casting no gucumura inzira ebyiri zitandukanye.Imbere mu gihugu umusaruro mwinshi wa casting Alnico.Imbaraga za rukuruzi zikoreshwa na magnetiki ya Alnico irashobora kugera kuri 9MGOe, kandi ifite ikintu kinini nuko irwanya ubushyuhe bwinshi, ubushyuhe bwakazi bushobora kugera kuri dogere selisiyusi 550.Nyamara, magnet ya Alnico iroroshye cyane demagnetize mumashanyarazi adahinduka.Niba usunikishije inkingi ebyiri za Alnico mu cyerekezo kimwe (ebyiri N cyangwa ebyiri S) hamwe, umurima wa imwe muri magneti uzasubizwa inyuma cyangwa uhindurwe.Kubwibyo, ntibikwiriye gukorerwa mumashanyarazi ahindagurika (nka moteri).
Alnico ifite ubukana bwinshi kandi irashobora kuba hasi no guca insinga, ariko kubiciro byinshi.Isoko rusange ryibicuruzwa byarangiye, hari ubwoko bubiri bwo gusya neza cyangwa kutasya.
Magnite ya Ferrite / Ceramic
Ferrite ni ubwoko bwa magnetiki butari metallic, nabwo buzwi nka ceramics ceramics.Dutandukanya radio isanzwe, kandi amahembe ya mahembe arimo ni ferrite.
Imiterere ya magnetique ya ferrite ntabwo iri hejuru, ibicuruzwa bitanga ingufu za magneti (kimwe mubipimo byo gupima imikorere ya magneti) birashobora gukora 4MGOe gusa hejuru gato.Ibikoresho bifite inyungu nini zo kuba bihendutse.Kugeza ubu, iracyakoreshwa henshi mubice byinshi
Ferrite ni ceramic.Kubwibyo, imikorere yimashini isa niy'ububumbyi.Magnite ya ferrite irabumbabumbwa, iracumura.Niba bikenewe gutunganywa, gusya byoroshye birashobora gukorwa.
Bitewe ningorabahizi yo gutunganya imashini, kuburyo rero imiterere ya ferrite iroroshye, kandi kwihanganira ubunini ni binini.Ibicuruzwa bifite imiterere ya kare nibyiza, birashobora gusya.Kuzenguruka, muri rusange gusya indege ebyiri gusa.Ubundi kwihanganira ibipimo bitangwa nkijanisha ryibipimo byizina.
Kuberako magnite ya ferrite yakoreshejwe mumyaka mirongo, abayikora benshi bafite impeta ziteguye, kare hamwe nibindi bicuruzwa byuburyo busanzwe nubunini bwo guhitamo.
Kuberako ferrite ari ibikoresho byubutaka, mubyukuri ntakibazo kibora.Ibicuruzwa byarangiye ntibisaba kuvurwa hejuru cyangwa gutwikira nka electroplating.
