Ozibuthe be-NdFeB, abaziwa nangokuthi omazibuthe be-neodymium, bangamazibuthe abangapheli abenziwe nge-alloy ye-neodymium, insimbi ne-boron.Baziwa ngezici zabo eziqinile kazibuthe, lawa mamagnet asetshenziswa kakhulu ezimbonini ezihlukahlukene, kuhlanganise ne-electronics, imoto namandla avuselelekayo.Kunezinhlobo ezahlukene zezidonsa ze-NdFeB, kufaka phakathiomazibuthe be-NdFeB ababoshiwe ngokwezifisofuthiizibuthe ze-neodymium ezihlanganisiwe.
Ozibuthe be-neodymium be-Sinteredziwuhlobo oluvame kakhulu lwezibuthe ze-NdFeB.Zenziwa ngenqubo ebizwa ngokuthi i-sintering, lapho izinto ezingavuthiwe zincibilikiswa esithandweni bese zipholiswa ukuze zakhe izinto eziqinile.Ozibuthe abakhona banamandla ensimu ephezulu futhi bangasetshenziswa ezinhlelweni ezidinga izizibuthe ezinamandla, njengamamotho kagesi, amajeneretha kanye nezihlukanisi kazibuthe.
Ngakolunye uhlangothi, omazibuthe be-NdFeB ababoshelwe ngokwezifiso, benziwa ngokuxuba impushana ye-NdFeB nesibophezelo se-polymer bese becindezela ingxube ibe yisimo oyifunayo.Inqubo ingakhiqiza omazibuthe abanobumo nobukhulu obuyinkimbinkimbi, okubenza bafanelekele uhla olubanzi lwezinhlelo zokusebenza.Omazibuthe be-NdFeB ababoshwe ngokwezifisozivame ukusetshenziswa ezimbonini lapho ukuguquguquka komklamo kanye nokusebenza kahle kwezindleko kubalulekile, njengezinzwa, ama-actuator kanye nezingxenye kazibuthe.
Kokubili omazibuthe be-neodymium abane-sintered kanye nozibuthe be-neodymium ababoshwe ngokwezifiso banezinzuzo zabo kanye nokubi.Ozibuthe be-Sintered neodymium baziwa ngamandla abo kazibuthe aphezulu kanye nokumelana nokukhishwa kazibuthe, okubenza bafanelekele izinhlelo zokusebenza ezinzima.Kodwa-ke, zibuye zibe brittle futhi zingenwe kalula ukugqwala, zidinga ukumbozwa okukhethekile ukuze zivikeleke ezintweni zemvelo.
Ngakolunye uhlangothi, omazibuthe be-NdFeB ababoshelwe ngokwezifiso bavumelana nezimo futhi bangakhiqizwa ngamavolumu aphezulu ngezindleko eziphansi.Futhi banokumelana nokugqwala okungcono futhi bangasetshenziswa ezinhlelweni laphoizibuthe ze-neodymium ezihlanganisiweingase ingafaneleki.Nokho, amandla azo azibuthe aphansi uma kuqhathaniswa nozibuthe be-sintered neodymium futhi angase angalungeli izinhlelo zokusebenza ezisebenza kahle kakhulu.
Kafushane, omazibuthe be-NdFeB abasikiwe kanye nozibuthe be-NdFeB abahlanganisiwe bayizinhlobo ezimbili ezihlukene zozibuthe be-NdFeB, ngayinye inezici zayo ezihlukile kanye nezinhlelo zokusebenza.Ozibuthe be-Sintered neodymium baziwa ngamandla abo kazibuthe aphezulu kanye nokumelana ne-demagnetization, okubenza bafanelekele izinhlelo zokusebenza ezinzima, kuyilapho.omazibuthe be-NdFeB ababoshiwe ngokwezifisonikeza ukuguquguquka komklamo kanye nokusebenza kahle kwezindleko.Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili zozibuthe be-NdFeB kubalulekile ekukhetheni uzibuthe ofanele wohlelo oluthile.
