Yadda za a kauce wa lalatawar maganadisu?

Idan aka kwatanta da ferrite da sauran kayan maganadisu na dindindin, magnet neodymium (NdFeB magnet) yana da kyakkyawan maganadisu kuma shine maɗaukakin ƙasa da aka fi amfani dashi.An yi amfani da shi sosai a cikin kayan lantarki, injin wuta, kayan aikin likita, kayan wasan yara, marufi, injinan hardware, sararin samaniya da sauran fannoni.Koyaya, maganadisu neodymium (magantattun NdFeB) suna da saurin lalacewa.Don haka ta yaya za a guje wa lalatawar neodymium magnet?Akwai hanyoyin gabaɗaya masu zuwa:
1. Phosphate
Phosphating tsari ne na sinadarai da halayen lantarki don samar da fim ɗin jujjuya sinadarai na phosphate.Phosphating yana da dalilai masu zuwa:
1. Kare tushe karfe daga lalata zuwa wani iyaka.
2. Ana amfani da shi azaman firamare kafin zanen don inganta mannewa da juriya na lalata fim.
3. Yana taka rawa na rage juzu'i da lubrication a cikin aiwatar da aikin sanyi na ƙarfe.
2. Electroplating
Electroplating shine tsari na sanya wani sirara mai sirara na wasu karafa ko gami a saman sauran karafa ta hanyar lantarki.Tsarin electroplating shine tsarin amfani da electrolysis don haɗa saman karafa ko wasu kayan zuwa fim ɗin ƙarfe, don hana iskar oxygenation na ƙarfe (kamar lalata), haɓaka juriya, haɓakawa, tunani, juriya na lalata da haɓaka tasirin kwalliya.
3. Electrophoresis
Ƙarƙashin aikin filin lantarki, ɓangarorin da aka caje suna motsawa zuwa ga electrode kishiyar wutar lantarki, wanda ake kira electrophoresis.Fasahar rarraba ɓangarorin da aka caje ta hanyoyi daban-daban na barbashi da aka caje a filin lantarki ana kiransa electrophoresis.Electrophoresis yana ɗaya daga cikin fasahar jiyya ta fuskar lalata da aka yi amfani da ita sosai a cikin sintered Nd-Fe-B da haɗin gwanon Nd-Fe-B na dindindin.A electrophoretic shafi ba kawai yana da kyau adhesion zuwa saman porous maganadiso, amma kuma yana da halaye na gishiri fesa, acid da alkali lalata juriya.
