Ibigize AlNiCo
Imashini ya Alniconi kimwe mubintu byambere byateje imbere ibikoresho bya magneti bihoraho, ni umusemburo ugizwe na aluminium, nikel, cobalt, icyuma nibindi bikoresho byuma. Alnico ibikoresho bya magneti bihoraho byakozwe neza muri 1930. Mbere yo kuvumbura isi idasanzwe ya magneti ihoraho mu myaka ya za 1960, aluminium-nikel-cobalt alloy yamye ari ibikoresho bikomeye bya magnetiki bihoraho, ariko kubera guhimba ibyuma byingenzi bya cobalt na nikel, bikavamo ibiciro byinshi, hamwe no kuza kwa ferrite ya magneti ihoraho hamwe nubutaka budasanzwe magnet, aluminium-nikel-cobalt mubikoresho byinshi byasimbuwe buhoro buhoro. Ariko, mubushuhe bwo hejuru bwo gusaba hamwe narukuruziibisabwa bihamye, magnet aracyafite umwanya utajegajega.
Ibikorwa bya Alnico nibikorwa
Alnico rukuruziKugira inzira ebyiri zo gukina no gucumura, kandi inzira yo gukina irashobora gutunganywa mubunini no muburyo butandukanye; Ugereranije nuburyo bwo gukina, ibicuruzwa byacumuye bigarukira ku bunini buto, kwihanganira ingano yubusa byakozwe ni byiza kuruta ibicuruzwa byashizwemo ubusa, umutungo wa magneti uri munsi gato ugereranije n’ibicuruzwa, ariko imashini ni byiza.
Igikorwa cyo kubyaza umusaruro aluminium nikel cobalt ni ugupima → gushonga → guta → kuvura ubushyuhe → gupima imikorere → gutunganya → kugenzura → gupakira.
Icuma cya aluminium nikel cobalt ikorwa nifu ya metallurgie, inzira yumusaruro irategura → ifu ikora → gukanda → gucumura treatment kuvura ubushyuhe → gupima imikorere → gutunganya → kugenzura → gupakira.
Imikorere ya AlNiCo
Ibisigisigi bya magnetiki bisigaye by'ibi bikoresho ni byinshi, bigera kuri 1.35T, ariko imbaraga zabo zo mu nda ni nkeya cyane, ubusanzwe munsi ya 160 kA / m, umurongo wa demagnetisation ni impinduka zidafite umurongo, kandi nikel ya aluminium nikel cobalt ihoraho ya magneti ntago ihura hamwe na demagnetisiyonike, bityo rero hagomba kwitonderwa umwihariko wacyo mugihe cyo gushushanya no gukora uruziga rukuruzi rwibikoresho. Imashini ihoraho igomba guhagarara mbere. Kurugero rwa anisotropic intera hagati ya AlNiCo alloy, ibigize Alnico-6 ni 8% Al, 16% Ni, 24% Co, 3% Cu, 1% Ti, naho ibindi ni Fe. Alnico-6 ifite BHmax ya 3.9 megagauss-oesteds (MG · Oe), agahato ka 780 oersted, ubushyuhe bwa Curie bwa 860 ° C, n'ubushyuhe bwo hejuru bwa 525 ° C. Ukurikije imbaraga nke za magneti ya Al-Ni-Co ihoraho, birabujijwe rwose guhura nibikoresho byose bya ferromagnetiki mugihe cyo kuyikoresha, kugirango bidatera demagnetisation yaho idasubirwaho cyangwa kugorekarukuruzigukwirakwiza ubucucike.
Byongeye kandi, kugirango ushimangire imbaraga zayo zo kurwanya demagnetisiyonike, ubuso bwa magnetiki ya Alnickel-cobalt ihoraho akenshi iba ikozwe ninkingi ndende cyangwa inkoni ndende, kubera ko ibikoresho bya magnetiki ya alnickel-cobalt bihoraho bifite imbaraga nke zubukanishi, ubukana bwinshi nubukonje, bikavamo mumashini idahwitse, ntabwo rero ishobora gushushanywa nkigice cyubatswe, kandi umubare muto gusa wo gusya cyangwa EDM urashobora gutunganywa, kandi guhimba nibindi gutunganya imashini ntibishobora gukoreshwa. Hangzhou Magnet Power Technology Co., Ltd. ifite ubushobozi bwo gusya neza bwibicuruzwa, gutunganya neza birashobora kugenzurwa muri mm +/- 0.005, kandi bifite ubushobozi bwo gukora no gutunganya ibicuruzwa bidasanzwe, byaba ibicuruzwa bisanzwe cyangwa ibicuruzwa bidasanzwe-byihariye, dushobora gutanga inzira na gahunda ikwiye.
Ahantu ho gukoreshwa muri Alnico
Ibicuruzwa bya aluminium-nikel-cobalt bikoreshwa cyane mugupima, imashini zikoresha ibikoresho, ibice byimodoka, amajwi yo mu rwego rwo hejuru, ibikoresho bya gisirikare hamwe nindege nizindi nzego. Icuma cya aluminiyumu nikel cobalt ikwiranye no gukora ibicuruzwa bigoye, byoroheje, binanutse, bito, cyane cyane bikoreshwa mu itumanaho rya elegitoronike, ibikombe bya magneti bihoraho, ibyuma bya magnetoelectric hamwe na sensor zitandukanye Ibicuruzwa byinshi byinganda n’abaguzi bigomba gukoresha magnesi zihoraho, nka moteri, amashanyarazi ya gitari yamashanyarazi, mikoro, disikuru zikoresha sensor, ingendo zingendo zingendo, (cowmagnet) nibindi. Bose bakoresha aluminium-nikel-cobalt. Ariko ubu, ibicuruzwa byinshi birahinduka kugirango bikoreshe isi idasanzwe, kubera ko ubwoko bwibintu bushobora gutanga Br ikomeye na BHmax yo hejuru, bigatuma ibicuruzwa bito bito.
