The luso amafuna NdFeb maginito mu ndondomeko kupanga

Ukadaulo wachitetezo cha Chemical waNdfeb Neodymium Magnetmakamaka zikuphatikizapo electroplating ndi electroless plating wa zokutira zitsulo, filimu kusintha kwa zokutira ceramic ndi kupopera mbewu mankhwalawa ndi electrophoresis wa zokutira organic.Popanga, nthawi zambiri amagwiritsidwa ntchito pokonzekera zokutira zoteteza zitsulo pamwamba pa maginito a NdFeb pogwiritsa ntchito njira ya electroplating.Electroplating ndi njira imene maginito workpiece ntchito monga cathode ndi zitsulo cation mu njira electroplating yafupika pamwamba maginito ntchito kunja panopa kupanga ❖ kuyanika zitsulo.Chitetezo cha electroplating chaMaginito a Sintered Neodymiummakamaka kusintha dzimbiri kukana maginito, komanso kusintha pamwamba makina katundu ndi kukongoletsa.

Patapita zaka kupanga ndi ntchito, ndi zolakwika za NdFeb maginito electroplating zoteteza ❖ kuyanika ndi zoonekeratu: The porosity wa ❖ kuyanika ndi lalikulu, ❖ kuyanika si wandiweyani, ndipo ali mawonekedwe kulolerana.Ngodya ya workpiece idzakulitsidwa chifukwa cha kuchuluka kwa chingwe chamagetsi mu njira ya electroplating, kotero ngodya yaRare Earth Permanent Magnetziyenera kugwedezeka, ndipo chitsanzo cha dzenje lakuya sichingapangidwe.Electroplating process imawononga matrix a maginito.Nthawi zina zovuta, pambuyo poti zokutira electroplating ntchito kwa nthawi yaitali, ❖ kuyanika adzawoneka ang'ambike, peeling, zosavuta kugwa ndi mavuto ena, ndipo ntchito chitetezo adzachepa.Ndi kusintha kwa chidziwitso cha chilengedwe, gawo la mtengo wonse wa electroplating atatu kuchotsa zinyalala ukuwonjezeka kwambiri. 

Neodymium Electromagnetukadaulo wa nickel plating umatanthawuza machitidwe a REDOX a mchere wachitsulo ndi chochepetsera posamba popanda kuwonjezera pakali pano.Pansi pa chothandizira cha workpiece pamwamba, ndondomeko ya zitsulo chitsulo kuchepetsa mafunsidwe.Poyerekeza ndi electroplating, electroless plating ndondomeko zipangizo ndi losavuta, safuna mphamvu ndi elekitirodi wothandiza, makulidwe ❖ kuyanika ndi yunifolomu, makamaka oyenera mawonekedwe a workpiece zovuta, zakuya dzenje mbali, chitoliro mkati khoma pamwamba plating, kachulukidwe ndi kuuma kwa ❖ kuyanika. ndi apamwamba.Electroless plating alinso ndi zolephera, makulidwe ❖ kuyanika sapita mmwamba, akhoza yokutidwa zosiyanasiyana si zambiri, ndondomeko zofunika ndi mkulu, kusamba kukonza ndi zovuta.Chemical plating makamaka nickel plating, copper plating ndi siliva plating.

Komanso, ndondomeko yaMaginito a Sintered Neodymiumsachedwa mabowo yaying'ono, dongosolo lotayirira, pamwamba akhakula ndi zolakwika zina, ndi NdFeb okhazikika maginito ntchito malo ntchito nthawi zambiri kutentha, chinyezi mkulu.zolakwika izi kupereka zinthu yabwino kwa NdFeb maginito dzimbiri mu kutentha ndi mkulu chinyezi chilengedwe.Pa nthawi yomweyo, kupanga ndondomeko NdFeB n'zosavuta muli O, H, Cl ndi zosafunika zina ndi mankhwala awo, zikuwononga zotsatira ndi O ndi Cl zinthu, maginito ndi O makutidwe ndi okosijeni dzimbiri, ndi Cl ndi mankhwala ake imathandizira makutidwe ndi okosijeni. ndondomeko ya maginito.Zifukwa za dzimbiri mosavuta wa NdFeb maginito makamaka chifukwa: malo ogwira ntchito, kapangidwe zinthu ndi luso kupanga.Kafukufuku akusonyeza kuti dzimbiri wa NdFeB maginito makamaka zimachitika m'madera atatu otsatirawa: ofunda ndi chinyezi chilengedwe, electrochemical chilengedwe, nthawi yaitali kutentha chilengedwe mu malo youma, pamene kutentha ndi otsika kuposa 150 ℃, ndi makutidwe ndi okosijeni mlingo wa NdFeb maginito kwambiri. pang'onopang'ono.
