Yaya karfi ne tsotsa na NdFeB karfi maganadiso?

 

NdFeB maganadiso a halin yanzu sune mafi ƙarfi na dindindin maganadisu. NdFeB maganadisu ne a halin yanzu mafi yawan kayan maganadisu na kasuwanci. An san su da sunan sarki na maganadisu. Suna da kaddarorin maganadisu na musamman da kuma iyakar su Samfuran makamashin maganadisu (BHmax) ya fi sau 10 sama da na ferrite. Har ila yau, shi ne magnetin duniya da aka fi amfani da shi a halin yanzu, kuma shi ana amfani da shi a sassa da kayan aiki da yawa kamar maganadisu na dindindin na gama-gari injina, faifan diski, da hoton maganadisu.

 

Nasa machinability shima yayi kyau. Yanayin aiki zai iya kaiwa har zuwa 200 digiri Celsius. Bugu da ƙari, rubutunsa yana da wuyar gaske, aikinsa yana da kwanciyar hankali, kuma yana da kyakkyawan aiki na farashi, don haka aikace-aikacen sa yana da faɗi sosai. Amma saboda aikin sinadarai mai ƙarfi, dole ne a bi da shi da ƙasa shafi. (Kamar Zn, Ni plating, electrophoresis, passivation, da dai sauransu).

 

Babban bangaren NdFeB maganadiso ba kasafai ne na duniya neodymium ba. Rare ƙasa ba da ake kira rare earth saboda ƙarancin maida hankali, amma ya fi wuya daban fiye da sauran kayan da aka haɗa ta hanyar haɗin sinadarai. Ko da yake jan hankali na maganadisu NdFeB yana da ƙarfi sosai, har ma ana jita-jita cewa NdFeB maganadiso na iya sha sau 600 nauyin nasu. Amma a gaskiya, wannan sanarwa ba ta cika ba, saboda jan hankali na maganadisu shima ya shafi yanayi da yawa kamar siffa da nisa. Misali, don maganadiso tare da diamita iri ɗaya, mafi girma da maganadisu, da karfi da karfin jan hankali na maganadisu; ga maganadiso da wannan tsawo, da ya fi girma da diamita, mafi girma da ƙarfin jan hankali.
