Ukuqulunqwa kwe-AlNiCo
Alnico umazibutheyenye yezinto zokuqala eziphuhliswe yimagnethi esisigxina, yi-alloy eyenziwe nge-aluminiyam, nickel, i-cobalt, isinyithi kunye nezinye izinto zentsimbi. Imathiriyeli yemagnethi esisigxina yeAlnico yaphuhliswa ngempumelelo ngeminyaka yoo-1930. Ngaphambi kokuveliswa kwezinto ezinqabileyo zomhlaba ezisisigxina zemagnethi kwiminyaka yee-1960, i-aluminium-nickel-cobalt alloy ibisoloko iyeyona nto inamandla yemagnethi esisigxina, kodwa ngenxa yokwakheka kweentsimbi ze-cobalt kunye ne-nickel, okukhokelela kwiindleko eziphezulu, ngokufika kwe Imagnethi esisigxina yeferrite kunye nemagnethi esisigxina yomhlaba enqabileyo, izinto ze-aluminium-nickel-cobalt kwizicelo ezininzi zitshintshwa ngokuthe ngcembe. Nangona kunjalo, kwezinye izicelo eziphezulu zobushushu kunyehigh magneticiimfuno zozinzo, umazibuthe usahleli kwindawo engashukumiyo.
Inkqubo yemveliso ye-Alnico kunye ne-brand
Alnico imagnethizibe neenkqubo ezimbini zokuphosa kunye ne-sintering, kwaye inkqubo yokuphosa inokucutshungulwa kwiisayizi ezahlukeneyo kunye neemilo; Xa kuthelekiswa nenkqubo yokuphosa, imveliso ye-sintered inqunyelwe kubukhulu obuncinci, ukunyamezela ubungakanani bendawo engenanto eveliswayo ingcono kunemveliso ephosiweyo engenanto, ipropathi yamagnetic ingaphantsi kancinane kuneyemveliso ephosiweyo, kodwa ubugcisa ngcono.
Inkqubo yemveliso yokuphosa i-aluminiyam ye-nickel cobalt idibanisa → ukunyibilika → ukuphosa → unyango lobushushu → uvavanyo lokusebenza → umatshini → ukuhlola → ukupakishwa.
I-cobalt ye-aluminiyam ye-nickel e-sintered iveliswa ngumgubo we-metallurgy, inkqubo yokuvelisa i-batching → ukwenza umgubo → ukucinezela → i-sintering → unyango lobushushu → uvavanyo lokusebenza → umatshini → ukuhlola → ukupakishwa.
Ukusebenza kwe-AlNiCo
Ukuxinwa kwemagnethi okushiyekileyo kwesi sixhobo kuphezulu, ukuya kuthi ga kwi-1.35T, kodwa ukunyanzeliswa kwabo kwangaphakathi kuphantsi kakhulu, ngokuqhelekileyo kungaphantsi kwe-160 kA/m, ijika layo le-demagnetization ayitshintshi, kwaye i-aluminium nickel cobalt esisigxina yemagnethi loop ayihambelani. kunye nejiko le-demagnetization, ke ingqalelo ekhethekileyo kufuneka ihlawulwe kubunjani bayo xa kuyilwa kwaye kusenziwa isekethe yemagnethi yesixhobo. Umazibuthe osisigxina kufuneka uzinziswe kwangaphambili. Umzekelo we-alloy anisotropic ephakathi kwe-alNiCo, ukubunjwa kwe-Alnico-6 ngu-8% Al, 16% Ni, 24% Co, 3% Cu, 1% Ti, kunye nezinye ziyi-Fe. I-Alnico-6 ine-BHmax ye-3.9 megagauss-oesteds (MG·Oe), i-coercivity ye-780 oersted, i-Curie yokushisa ye-860 ° C, kunye neqondo lokushisa eliphezulu le-525 ° C. Ngokokunyanzeliswa okuphantsi kwe-Al-Ni-Co imathiriyeli yamagnetic esisigxina, kuthintelwe ngokungqongqo ukunxibelelana nayo nayiphi na imathiriyeli ye-ferromagnetic ngexesha lokusetyenziswa, ukuze ingabangeli ukuchithwa kweemagnethi okungenakuguqulwa okanye ukugqwethwa kwe-iron.imagnethiukuxinana kosasazo.
Ukongeza, ukomeleza ukuchasana kwayo ne-demagnetization, umphezulu we-alnickel-cobalt i-magnetic pole ihlala iyilwe ngeekholamu ezinde okanye iintonga ezinde, kuba i-alnickel-cobalt esisigxina yemagnethi inamandla omatshini aphantsi, ubunzima obuphezulu kunye nokuqina. kwi-machinability embi, ngoko ayinakuyilwa njengenxalenye yesakhiwo, kwaye kuphela inani elincinci lokusila okanye i-EDM inokucutshungulwa, kunye nokuqulunqa kunye nokunye ukuqhutyelwa komatshini. ayinakusetyenziswa. I-Hangzhou Magnet Power Technology Co., Ltd. inekhono lokusila elichanekileyo le mveliso, ukuchaneka kokucubungula kunokulawulwa ngaphakathi kwe-+/-0.005 mm, kwaye inokuvelisa kunye nokukwazi ukuvelisa iimveliso ezikhethekileyo, nokuba ziimveliso eziqhelekileyo okanye iimveliso ezikhethekileyo ezikhethekileyo, sinokunika indlela efanelekileyo kunye neprogram.
Iindawo zokusetyenziswa kwe-Alnico
Iimveliso zeCast aluminium-nickel-cobalt zisetyenziswa ikakhulu kumlinganiso, imagnethi yesixhobo, iinxalenye zemoto, i-audio ephezulu, izixhobo zomkhosi kunye ne-aerospace kunye namanye amasimi. I-aluminium ye-nickel ye-sintered ilungele ukuveliswa kwezinto eziyinkimbinkimbi, ezikhanyayo, ezincinci, ezincinci, ezisetyenziswa ikakhulu kunxibelelwano lwe-elektroniki, iikomityi zemagnethi ezisisigxina, ukutshintshwa kwemagnetoelectric kunye nezinzwa ezahlukeneyo Iimveliso ezininzi zemizi-mveliso kunye nabathengi kufuneka zisebenzise imagnethi eqinile, enjengeemoto; Imifanekiso yegitare yombane, iimakrofoni, izithethi zoluvo, iityhubhu ezihambayo zamaza, (i-cowmagnet) njalo njalo. Bonke basebenzisa iimagnethi ze-aluminium-nickel-cobalt. Kodwa ngoku, iimveliso ezininzi zitshintsha ukusebenzisa iimagnethi zomhlaba ezinqabileyo, kuba olu hlobo lwezinto eziphathekayo lunokunika i-Br enamandla kunye ne-BHmax ephezulu, evumela ukuba umthamo omncinci wemveliso.
