Xav txog kev siv cov hlau nplaum neodymium sib txuas rau koj daim ntawv thov yog tias sintered neodymium yuav yog qhov kev xaiv zoo dua vim nws qhov yooj yim dua. Cov hlau nplaum no yog tsim los ntawm cov hmoov neodymium uas tau raug khi. Ib tug polymer yog ua ke nrog melted hmoov. Cov khoom tiav lawm ces ua los ntawm nias los yog extruding cov khoom. Cov hlau nplaum neodymium uas tau muab khi ua ke tuaj yeem sib nqus rau hauv cov qauv tsim nrog ntau tus ncej. Bonded neodymium hlau nplaum muaj ntau qhov tsim tau yooj yim txawm tias lawv tsis muaj zog dua li sintered neodymium hlau nplaum. Tsis tas li ntawd, lawv muaj qhov ntsuas kub qis dua (coercivity) thiab sib dua li samarium cobalt. Txawm li cas los xij, lawv muaj txiaj ntsig zoo rau cov ntawv thov uas hu rau cov hlau nplaum me me lossis siv cov nplhaib radial.
Cov khoom muaj zog Nd-Fe-B yog sib xyaw nrog epoxy khi los tsim cov hlau nplaum Neodymium sib raug zoo. Txog 97 vol feem pua ntawm qhov sib tov yog cov khoom siv hlau nplaum, thiab 3 vol feem pua yog epoxy. Nd-Fe-B hmoov thiab epoxy binder tau ua ke thaum lub sijhawm tsim khoom, uas tseem suav nrog kev sib xyaw cov khoom sib xyaw hauv xovxwm thiab kho qhov chaw hauv qhov cub. Txij li thaum cov khoom tsim los siv compression bonding, qhov khiav qhov ntev yuav txawv tsis ntau tshaj.002 ntiv tes.
Bonded neodymium-iron-boron (NdFeB) hlau nplaum yog cov hlau nplaum muaj zog uas siv rau ntau yam kev siv. Rau cov hlau nplaum NdFeB sib raug zoo, epoxy txheej yog feem ntau siv. Electroless nickel plating kuj tseem siv los tiv thaiv corrosion. Txhua qhov kev taw qhia lossis ntau tus ncej yuav raug siv los ua kom cov khoom siv isotropically khi NdFeB.
Ua isotropic, bonded Nd-Fe-B cov ntaub ntawv tuaj yeem sib nqus hauv txhua qhov kev taw qhia, suav nrog ntau qhov kev teeb tsa polar. Cov khoom yuav raug machined ntawm lub zeb los yog tshuab dhos vim nws yog nyob rau hauv ib tug epoxy binder. Txawm li cas los xij, qhov tsis tuaj yeem tapping vim cov khoom yuav tsis txhawb nqa ib txoj xov. Txhawm rau kom txo qis qhov loj ntawm cov qauv tsim uas siv cov khoom siv hlau nplaum ceramic, cov khoom siv Nd-Fe-B feem ntau siv. Cov khoom siv yog kwv yees li peb zaug muaj zog dua li cov khoom siv hlau nplaum ceramic, tso cai rau txo qhov loj me. Cov khoom siv kuj tuaj yeem sib nqus tau ntau-polarly vim nws yog isotropic, xws li los ntawm kev tsim cov qauv NSNS ntawm lub nplhaib sab nraud.
