Kedu ike bụ mmịpụta nke NdFeB magnetik siri ike?

 

NdFeB ihe ndọta bụ ihe ndọta na-adịgide adịgide kachasị ike ugbu a. NdFeB magnet bụ ugbu a ihe ndọta kacha dịnụ. A maara ha dị ka eze nke magnetism. Ha nwere ihe ndọta dị oke elu yana oke ha ngwaahịa ike magnetik (BHmax) karịrị ugboro iri karịa nke ferite. Ọ bụkwa ihe ndọta ụwa nke na-adịghị ahụkebe na-ejikarị eme ihe ugbu a, yana ya a na-eji n'ọtụtụ akụkụ na ngwá ọrụ dị ka magnet na-adịgide adịgide anyị moto, draịva diski, na onyonyo resonance magnetik.

 

Nke ya machinability dịkwa ezigbo mma. Ọnọdụ okpomọkụ na-arụ ọrụ nwere ike iru 200 ogo Celsius. Ọzọkwa, udidi ya siri ike, arụmọrụ ya kwụsiri ike, na ọ nwere ezigbo ụgwọ ọrụ, ya mere ngwa ya dị oke oke. Ma n'ihi ọrụ kemịkal siri ike ya, a ghaghị iji elu mee ya mkpuchi. (dị ka Zn, Ni plating, electrophoresis, passivation, wdg).

 

Isi Akụkụ nke ndọta NdFeB bụ ihe neodymium dị ụkọ n'ụwa. Obere ụwa abụghị a na-akpọ ụwa na-adịghị ahụkebe n'ihi na ọ dị ntakịrị itinye uche, mana ọ na-esi ike karị dị iche iche karịa ihe ndị ọzọ ejikọtara site na njikọ kemịkalụ. Agbanyeghị na ndọta ndọta nke NdFeB ndọta siri ike, a na-anụkwa ya na ya Ihe ndọta NdFeB nwere ike ịmịkọrọ 600 ugboro ibu nke ha. Ma n'ezie, nke a nkwupụta abụghị nke ukwuu, n'ihi na ndọta ndọta bụkwa emetụta ọtụtụ ọnọdụ dịka ọdịdị na anya. Dịka ọmụmaatụ, maka magnet na otu dayameta, nke dị elu magnet, otú ahụ siri ike ike ndọta; n'ihi na magnetik na otu ịdị elu, ibu na dayameta, ka ike ndọta na-adọrọ adọrọ karị.
