SmCo Magnets VS Sintered NdFeB Magnets
Tse latelang ke phapang ea mantlha lipakeng tsa limakete tsa NdFeB tse sirelelitsoeng le limatlase tsa SmCo:
1. Matla a makenete:
Matla a khoheli a Magnet a Permanent Neodymium a maholo ho feta a SmCo Magnet. Sintered NdFeB e na le (BH)Max ho fihla ho 55MGOe, athe thepa ea SmCo e na le (BH)Max ea 32MGOe. Ha ho bapisoa le thepa ea NdFeb, lisebelisoa tsa SmCo li molemo ho hanela demagnetization.
2. Ho hanyetsa mocheso o phahameng
Mabapi le ho hanyetsa mocheso o phahameng, NdFeB ha e betere ho feta SmCo. NdFeB e khona ho mamella mocheso ho fihla ho 230 °C athe SmCo e khona ho mamella mocheso ho fihla ho 350 °C.
3. Ho hanyetsa kutu
Limanete tsa NdFeB li sokola ho mamella kutu le oxidation. Ka tloaelo, li hloka ho koaheloa kapa ho phutheloa ka vacuum ho li sireletsa. Zinc, nickel, epoxy, le lisebelisoa tse ling tsa ho roala li sebelisoa khafetsa. Magnets a entsoeng ka SmCo a ke ke a rusa.
4. Sebopeho, tshebetso, le ho kopanya
Ka lebaka la ho fokola ha tsona, NdFeb le SmCo li ke ke tsa hlahisoa ka mekhoa e tloaelehileng ea ho itšeha. Ho itšeha ka mabili a daemane le li-electrode tsa terata ke mekhoa e 'meli e meholo ea ho sebetsa. Sena se fokotsa mefuta ea limakete tsena tse ka hlahisoang. Libopeho tse rarahaneng haholo li ke ke tsa sebelisoa. Lisebelisoa tsa SmCo li brittle ebile lia robeha ha li bapisoa le lisebelisoa tse ling. Ka hona, ha u haha le ho sebelisa makenete a SmCo, ka kopo ela hloko haholo.
5. Theko
Limanete tsa SmCo li ne li theko e boima habeli haeba li ne li sa theko e boima ka makhetlo a mararo, joalo ka limakete tsa NdFeB lilemong tse 'maloa tse fetileng. Ka lebaka la maano a thibelo a naha a merafong e etsoang seoelo, theko ea NdFeB e eketsehile haholo lilemong tsa morao tjena. Ha e le hantle, limatlase tse tloaelehileng tsa NdFeB li theko e tlase ho feta samarium cobalt.
