Kedu ihe bụ ihe ndọta a na-ejikarị na ya moto magnet na-adịgide adịgide?

Ihe ndọta na-adịgide adịgide nke a na-ejikarị na moto gụnyere ihe ndọta sintered na njikọ njikọ, ụdị ndị bụ isi bụ aluminum-nickel-cobalt, ferrite, samarium cobalt, NdFeB na ndị ọzọ.

Alnico: Alnico na-adịgide adịgide magnet ihe onwunwe bụ nke mbụ na n'ọtụtụ ebe na-eji na-adịgide adịgide magnet ihe onwunwe, na ya nkwadebe usoro na nkà na ụzụ bụ dịtụ tozuru okè.Ugbu a, e nwere ụlọ mmepụta ihe na Japan, United States, Europe, Russia na China.Among nnukwu-ọnụ ọgụgụ. mmepụta ụlọ ọrụ, mmepụta nke Hangzhou na-adịgide adịgide magnet bụ ugbu a nke mbụ na China, na-enwe kwa afọ ikike nke 3000 tọn.
Na-adịgide adịgide magnet ferrite ihe: banyere 50's, ferrite malitere ito eto, karịsịa na 70's, na coercivity, magnetik ike igwe arụmọrụ mma strontium-ferrite n'ime mmepụta na ọnụ ọgụgụ buru ibu, ngwa ngwa gbasaa ojiji nke na-adịgide adịgide magnet ferrite. a nonmetallic magnetik ihe, ferrite adịghị mfe oxidize dị ka metal na-adịgide adịgide magnet ihe, ala Curie okpomọkụ na elu na-eri, n'ihi ya, ọ bụ nnọọ ewu ewu.
Samarium cobalt ihe: ịrị elu nke narị afọ nke 20 na etiti 1960, magburu onwe magnetik na-adịgide adịgide magnet ihe, na nnọọ ike arụmọrụ.Samarium cobalt bụ karịsịa adabara n'ichepụta nke electric Motors si akụkụ nke magnetik Njirimara, ma n'ihi na ya elu. ọnụahịa, a na-ejikarị ya na nyocha na mmepe nke ụgbọ elu, ikuku, ngwá agha na ndị agha eletriki eletrik ndị ọzọ na arụmọrụ dị elu na ọnụahịa abụghị isi ihe na-eme ka nkà na ụzụ dị elu nke igwe eletrik.
NdFeB ihe onwunwe: NdFeB magnetik ihe onwunwe bụ neodymium, ígwè oxide na ndị ọzọ alloy, makwaara dị ka magnetik steel.With kemgwucha elu magnetik ike ngwaahịa na uru nke elu ike njupụta, NdFeB na-adịgide adịgide magnet ihe e ọtụtụ-eji na oge a ụlọ ọrụ na electronic technology. nke mere na-eme ka ngwá, electroacoustic Motors, magnetik nkewa na magnetization akụrụngwa miniaturization, ìhè arọ, mkpa ghọọ possible.It bụ ngwa ngwa ka nchara n'ihi na ya elu ọdịnaya nke neodymium na iron.Surface chemical passivation bụ otu n'ime ihe ngwọta kasị mma.
