Neodymium maganadiso su ne mafi kyawun maganadiso da ba za a iya jurewa ba a kasuwa, a ko'ina cikin duniya. juriya ga demagnetisation lokacin da aka bambanta da ferrite, alnico har ma da samarium-cobalt maganadiso.
✧ Neodymium maganadiso VS na al'ada ferrite maganadiso
Ferrite maganadiso su ne marasa ƙarfe abu maganadiso bisa triiron tetroxide (kafaffen rabon ƙarfe oxide zuwa ferrous oxide). Babban rashin lahani na waɗannan maganadiso shine ba za a iya ƙirƙira su yadda aka so ba.
Neodymium maganadiso ba kawai yana da kyakkyawan ƙarfin maganadisu ba, har ma yana da kyawawan kaddarorin inji saboda haɗakar ƙarfe, kuma ana iya sarrafa su cikin sauƙi zuwa siffofi daban-daban don dacewa da buƙatu daban-daban. Rashin hasara shi ne cewa ƙarfe monomers a cikin neodymium maganadiso yana da sauƙi ga tsatsa da lalacewa, don haka saman kuma sau da yawa ana sanya shi da nickel, chromium, zinc, tin, da dai sauransu don hana tsatsa.
✧ Haɗin gwiwar neodymium maganadisu
Neodymium maganadiso ana yin su ne da neodymium, baƙin ƙarfe da boron waɗanda aka haɗa su tare, yawanci ana rubuta su azaman Nd2Fe14B. Saboda ƙayyadadden abun da ke ciki da ikon samar da lu'ulu'u na tetragonal, ana iya la'akari da maganadisu neodymium kawai daga mahangar sinadarai. 1982, Makoto Sagawa na Sumitomo Special Metals ya ƙera neodymium maganadisu a karon farko. Tun daga wannan lokacin, Nd-Fe-B maganadiso an cire sannu a hankali daga ferrite maganadiso.
✧ Yaya ake yin maganadisu neodymium?
MATAKI 1- Da farko, duk abubuwan da za a yi zaɓaɓɓen ingancin maganadisu ana sanya su a cikin tanderun shigar da injin tsabtace injin, mai zafi da narke don haɓaka samfuran gami. Ana sanyaya wannan cakuda don samar da ingots kafin a nika shi daidai cikin kananan hatsi a cikin injin jet.
MATAKI NA 2- sannan ana danna foda mai kyau a cikin wani mold kuma a lokaci guda ana amfani da makamashin maganadisu a kan mold. Magnetism yana fitowa ne daga naɗaɗɗen kebul wanda ke aiki azaman maganadisu lokacin da wutar lantarki ta wuce ta cikinsa. Lokacin da tsarin barbashi na maganadisu ya dace da umarnin maganadisu, ana kiran wannan maganadisu anisotropic.
MATAKI NA 3- Wannan ba ƙarshen hanya ba ne, a maimakon haka, a wannan lokacin abubuwan da aka haɗa da magnet ɗin sun lalace kuma tabbas za su sami magnetized daga baya yayin yin haka. Mataki na gaba shi ne kayan da za a yi zafi, kusan har zuwa lokacin narkewa a cikin hanyar da ake kira Ayyukan da ke gaba shine don samfurin ya yi zafi, kusan har zuwa lokacin narkewa a cikin hanyar da ake kira sintering wanda ke sa ƙwanƙwarar magnet ɗin foda ya haɗu tare. Wannan hanya tana faruwa a cikin rashin isashshen oxygen, saitin inert.
MATAKI NA 4- Kusan a can, kayan zafi yana yin sanyi da sauri ta hanyar amfani da hanyar da aka sani da quenching. Wannan saurin sanyaya tsari yana rage wuraren da ba daidai ba kuma yana ƙara aiki.
MATAKI NA 5-Saboda gaskiyar cewa Magnetic neodymium yana da wuyar gaske, yana sa su iya lalacewa da lalacewa, dole ne a shafe su, tsaftace su, bushewa, da kuma faranti. Akwai nau'ikan gamawa iri-iri da yawa waɗanda aka yi amfani da su tare da magneto na neodymium, ɗayan mafi yawanci shine haɗin nickel-Copper-nickel amma ana iya shafa su a cikin wasu ƙarfe da kuma roba ko PTFE.
MATAKI 6- Da zaran an ɗora kayan da aka gama, za a sake ƙara haɓakawa ta hanyar saka shi a cikin nada, wanda idan aka zagaya wutar lantarki ta cikinsa yakan haifar da filin maganadisu sau uku fiye da ƙarfin da ake bukata na magnet.
