Ukunyangwa koMphezulu weemagnethi
Unyango lomphezulu weiimagnethi ze-neodymiumidlala indima ebalulekileyo ekusebenzeni nasekuphileni ixesha elide. Imagnethi yeNeodymium, ekwabizwa ngokuba ziimagnethi zeNdFeB, zimagnethi ezinamandla kakhulu ezisisigxina ezenziwe ngealloy yentsimbi, boron, kunye neodymium. Unyango lomphezulu lubhekisa kwinkqubo yokufaka umaleko okhuselayo okanye ukutyabeka kumphezulu ongaphandle wemagnethi ye-neodymium. Olu nyango luyimfuneko ukuze kuthintelwe umazibuthe ekungcoleni kunye nokuphucula ukuqina kwayo kukonke. Ezona ntlobo zixhaphakileyo zonyango lomphezulu wemagnethi ye-neodymium ziquka i-NiCuNi plating, i-Zinc plating, kunye ne-Epoxy coating.
Esinye sezizathu eziphambili zokuba kutheni unyango lomphezulu lubalulekile kwiimagnethi ze-neodymium kukuchanabeka kwazo kumhlwa. Imagnethi ye-Neodymium yenziwe ikakhulu ngentsimbi, ethanda ukurusa xa ivezwe kukufuma kunye neoksijini. Ngokusebenzisa i-coating ekhuselayo, i-corrosion ingancitshiswa kakhulu, ikhulise ixesha lokuphila lemagnethi.
Esinye isizathu sonyango olungaphezulu kukuphucula ukusebenza kwemagnethi. Ukugquma kunokubonelela nge-smooth surface, ukunciphisa ukungqubuzana kunye nokuvumela iimpawu ezingcono zamagnetic. Unyango oluthile lomphezulu, olufana ne-nickel plating okanye igolide, lunokuphucula ukuxhathisa umazibuthe kumaqondo obushushu aphezulu, luyenze ilungele izicelo ezibandakanya ubushushu. Unyango lwakumphezulu lukwavumela imagnethi ye-neodymium ukuba ihambelane neemeko ezahlukeneyo kunye nokusetyenziswa. Umzekelo, i-epoxy coatings inokubonelela nge-insulation, evumela ukuba imagnethi isetyenziswe kwizicelo zombane ngaphandle kokujikeleza okufutshane. Iingubo zokwaleka zinokukhusela umazibuthe kwiikhemikhali okanye ukuqhawuka, ziyenze ilungele ukusetyenziswa kwindawo ezonakalisayo okanye kwizicelo apho kukho ukukhuhlana kunye nokunxiba.
Unyango lomphezulu luyimfuneko kwimagnethi ye-neodymium ukukhusela kumhlwa, ukomeleza ukusebenza, ukonyusa ukuqina, kunye nokuqinisekisa ukuhambelana nendawo ethile kunye nezicelo. Ngokusebenzisa unyango olufanelekileyo lomphezulu, ixesha lokuphila kunye nokusebenza kweemagnethi ze-neodymium kunokuphuculwa kakhulu.
Apha ngezantsi kukho uludwe lokutyabeka/ukwaleka kunye neentsiba zazo kwireferensi yakho.

Iintlobo zeengubo zeemagnethi
NiCuNi: Ingubo ye-nickel yenziwe ngamaleko amathathu, i-nickel-copper-nickel. Olu hlobo lokugquma lolona lusetyenziswa kakhulu kwaye lubonelela ngokhuseleko lokubola kwemagnethi kwiimeko zangaphandle. Iindleko zokulungisa ziphantsi. Ubushushu obuphezulu bokusebenza bumalunga ne-220-240ºC (kuxhomekeke kubushushu obuphezulu bokusebenza kwemagnethi). Olu hlobo lokwambatha lusetyenziswa kwiinjini, iijenereyitha, izixhobo zonyango, izinzwa, usetyenziso lweemoto, ukugcinwa, iinkqubo zokubeka ifilimu encinci, kunye neepompo.
