Kodi kuyamwa kwa maginito amphamvu a NdFeB kuli kolimba bwanji?

Bwanji wamphamvu ndi kuyamwa kwa maginito amphamvu a NdFeB?

Ndi FeB maginito panopa ndi amphamvu kwambiri maginito okhazikika. Maginito a NdFeB ndi pakali pano maginito omwe amagulitsidwa kwambiri. Iwo amadziwika kuti mfumu wa magnetism. Iwo ali apamwamba kwambiri maginito katundu ndi pazipita awo Magnetic energy product (BHmax) ndi yoposa nthawi 10 kuposa ya ferrite. Ndiwonso maginito omwe amagwiritsidwa ntchito kwambiri padziko lapansi pano, komanso amagwiritsidwa ntchito mbali zambiri ndi zida monga maginito athu wamba okhazikika ma motors, ma disk drive, ndi kujambula kwa maginito a resonance.

Zake machinability ndi bwino ndithu. Kutentha kwa ntchito kumatha kufika ku 200 madigiri Celsius. Komanso, mawonekedwe ake ndi ovuta, ntchito yake ndi yokhazikika, komanso ili ndi ntchito yabwino yotsika mtengo, chifukwa chake kugwiritsa ntchito kwake ndikwambiri. Koma chifukwa cha mphamvu yake yamankhwala, iyenera kuthandizidwa ndi pamwamba zokutira. (Monga Zn, Ni plating, electrophoresis, passivation, etc.).

Chachikulu chigawo chimodzi cha maginito a NdFeB ndi osowa Earth element neodymium. Dziko lapansi losowa siliri amatchedwa dziko lachilendo chifukwa cha kuchepa kwake, koma ndizovuta kwambiri osiyana kuposa zipangizo zina zolumikizidwa ndi ma bonds a mankhwala. Ngakhale a maginito kukopa NdFeB maginito ndi wamphamvu kwambiri, ndi ngakhale mphekesera kuti Maginito a NdFeB amatha kuyamwa nthawi 600 kulemera kwawo. Koma kwenikweni, izi mawu si omveka, chifukwa maginito kukopa nawonso kukhudzidwa ndi zinthu zingapo monga mawonekedwe ndi mtunda. Mwachitsanzo, kwa maginito ndi m'mimba mwake chomwecho, ndi apamwamba maginito, ndi mphamvu mphamvu ya maginito yokopa; kwa maginito omwe ali ndi msinkhu womwewo, amakulirakulira m'mimba mwake, mphamvu ya maginito yokopa kwambiri.
