Jiyya na Magnets saman
A surface jiyya naneodymium maganadisuyana taka muhimmiyar rawa a cikin ayyukansu da tsawon rayuwarsu.Neodymium maganadiso, kuma aka sani da NdFeB maganadiso, suna da matuƙar ƙarfi na dindindin maganadiso da aka yi daga wani gami na baƙin ƙarfe, boron, da neodymium.Maganin saman yana nufin tsarin yin amfani da Layer na kariya ko rufi zuwa saman farfajiyar magnet neodymium.Wannan magani ya zama dole don hana maganadisu daga lalacewa kuma don haɓaka ƙarfinsa gabaɗaya.Mafi yawan nau'ikan jiyya na sama don maganadisu neodymium sun haɗa da plating na NiCuNi, plating na Zinc, da murfin Epoxy.
Ɗaya daga cikin manyan dalilan da ya sa jiyya na saman ke da mahimmanci ga maɗauran neodymium shine yiwuwar su ga lalata.Neodymium maganadiso da farko sun hada da baƙin ƙarfe, wanda ke da wuya ga tsatsa lokacin da aka fallasa shi ga danshi da oxygen.Ta hanyar yin amfani da murfin kariya, lalata za a iya ragewa sosai, yana ƙara tsawon rayuwar magnet.
Wani dalili na maganin saman shine don haɓaka aikin maganadisu.Rubutun na iya samar da wuri mai laushi, rage juzu'i da kuma ba da damar mafi kyawun halayen magnetic.Wasu jiyya na saman, irin su platin nickel ko platin zinare, na iya inganta juriyar maganadisu zuwa yanayin zafi mai yawa, yana sa ya dace da aikace-aikacen da suka haɗa da zafi.Magungunan saman kuma suna ba da damar maganadisu neodymium don dacewa da yanayi daban-daban da aikace-aikace.Misali, rufin epoxy na iya samar da rufin, yana ba da damar yin amfani da maganadisu a aikace-aikacen lantarki ba tare da gajeriyar kewayawa ba.Rubutun kuma na iya kare maganadisu daga sinadarai ko abrasion, yana mai da shi dacewa da amfani a cikin mahalli masu lalata ko a aikace-aikacen da akwai gogayya da sawa.
Jiyya na saman suna da mahimmanci don maganadisu neodymium don karewa daga lalata, haɓaka aiki, ƙara ƙarfi, da tabbatar da dacewa tare da takamaiman yanayi da aikace-aikace.Ta hanyar amfani da jiyya mai dacewa, tsawon rayuwa da tasiri na maganadisu neodymium za a iya ingantawa sosai.
A ƙasa akwai jerin sutura/shafi da gashin fuka-fukan su don tunani.
