NdFeB hlau nplaum yog ib qho ntawm cov khoom siv hlau nplaum ruaj khov tshaj plaws tam sim no. Nws muaj lub zog ceev ceev, zoo heev corrosion kuj thiab stability. Txawm li cas los xij, thaum NdFeB hlau nplaum yog oxidized, cov tshuaj muaj pes tsawg leeg thiab lub cev ntawm lawv qhov chaw yuav hloov.
Ua ntej tshaj plaws, tom qab NdFeB hlau nplaum yog oxidized, oxide zaj duab xis yuav raug tsim. Cov oxide zaj duab xis no yog tsim los ntawm npib tsib xee oxide, hlau oxide thiab neodymium oxide. Cov oxide zaj duab xis no tuaj yeem tiv thaiv oxidation ntxiv ntawm NdFeB hlau nplaum, yog li tiv thaiv NdFeB hlau nplaum hauv cov hlau nplaum los ntawm kev puas tsuaj los ntawm oxidation.
Qhov thib ob, oxidation ntawm NdFeB hlau nplaum tsis muaj kev cuam tshuam ntau rau cov hlau nplaum. Los ntawm kev tshawb fawb nto thiab tsim nyog oxide zaj duab xis thickness tswj, cov khoom sib nqus ntawm cov hlau nplaum tuaj yeem lav tau ruaj khov thiab zoo heev.
Nws yog tsim nyog sau cia tias thaum ua oxidation kev kho mob, yuav tsum tau them nyiaj mloog mus rau kev tswj lub oxidation kub thiab oxidation lub sij hawm los xyuas kom meej qhov zoo thiab stability ntawm cov hlau nplaum. Tsis tas li ntawd, tom qab kev kho oxidation, cov kauj ruam xws li kev tu thiab kev soj ntsuam zoo kuj tseem yuav tsum tau ua kom ntseeg tau tias qhov kev ua tau zoo thiab zoo ntawm cov hlau nplaum ua tau raws li qhov yuav tsum tau ua.
Txawm hais tias cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv lub cev ntawm NdFeB hlau nplaum yuav hloov pauv ntawm nws qhov chaw tom qab oxidation, qhov ruaj khov thiab zoo heev sib nqus ntawm cov hlau nplaum tuaj yeem ua kom ntseeg tau los ntawm kev tshawb fawb nto thiab tsim nyog oxide zaj duab xis thickness tswj. Yog li ntawd, kev kho oxidation ntawm NdFeB hlau nplaum tuaj yeem txhim kho lawv cov kev tiv thaiv corrosion thiab kev ruaj ntseg, uas yog qhov zoo rau kev siv lawv lub neej kev pab cuam thiab ua kom muaj kev siv dav dua.
