Ubuchwepheshe bokuvikela amakhemikhali beI-Ndfeb Neodymium Magnetikakhulukazi ihlanganisa i-electroplating kanye ne-electroless plating yezingubo zensimbi, ifilimu yokuguqulwa kwezingubo zobumba kanye nokufutha kanye ne-electrophoresis yezingubo zemvelo.Ekukhiqizeni, kuvame ukusetshenziselwa ukulungisa i-metal protective coating ebusweni bukadonsa be-NdFeb ngenqubo ye-electroplating.I-Electroplating iyinqubo lapho i-workpiece kazibuthe isetshenziswa njenge-cathode futhi i-cation yensimbi kusixazululo se-electroplating iyancipha ebusweni bukazibuthe ngokusebenzisa i-current yangaphandle ukuze yakhe i-metal coating.Ukuvikelwa kwe-electroplating yeI-Sintered Neodymium Magnetsikakhulukazi ukuthuthukisa ukumelana nokugqwala kodonsa, kanye nokuthuthukisa izakhiwo zemishini nokuhlobisa.
Ngemva kweminyaka yokukhiqiza nokusetshenziswa, amaphutha e-NdFeb umazibuthe we-electroplating evikelayo abonakala ngokucacile: I-porosity ye-coating inkulu, i-coating ayiminyene, futhi inokubekezelelana komumo.Ikhoneni le-workpiece lizoqiniswa ngenxa yokugxila komugqa wamandla ohlelweni lwe-electroplating, ngakho-ke ikhonaI-Rare Earth Permanent Magnetkufanele i-chamfered, futhi isampula yembobo ejulile ayikwazi ukufakwa.Inqubo ye-Electroplating inomphumela olimazayo ku-matrix kazibuthe.Kwezinye izimo ezinzima, ngemuva kokusetshenziswa kwe-electroplating isikhathi eside, ukugqoka kuzovela ukuqhekeka, ukuxebuka, ukuwa kalula nezinye izinkinga, futhi ukusebenza kokuzivikela kuzokwehla.Ngokuthuthukiswa kokuqwashisa ngemvelo, ingxenye yezindleko eziphelele zokuhlanza imfucuza nge-electroplating ikhuphuka kakhulu.
I-Neodymium Electromagnetubuchwepheshe be-nickel plating bubhekisela ekuphenduleni kwe-REDOX kasawoti wensimbi kanye ne-ejenti yokunciphisa ekugezeni ngaphandle kokwengezwa kwamandla asetshenziswayo.Ngaphansi kwesenzo se-catalytic sendawo yokusebenza, inqubo yokubeka insimbi yokunciphisa i-ion.Uma kuqhathaniswa ne-electroplating, imishini yenqubo ye-electroless plating ilula, ayidingi amandla kanye ne-electrode eyisizayo, ukushuba kwe-coating yunifomu, ifaneleka ikakhulukazi ukuma kwe-workpiece eyinkimbinkimbi, izingxenye zembobo ejulile, ipayipi elingaphakathi lodonga lokucwenga, ukuminyana nokuqina kwe-coating. iphakeme.I-Electroless Plating ibuye ibe nokushiyeka okuthile, ukushuba kwe-coating akukhuphuki, kungenziwa ukugoqa okuhlukahlukene akukuningi, izidingo zenqubo ziphakeme kakhulu, ukugcinwa kokugeza kuyinkimbinkimbi.I-Chemical Plating ngokuyinhloko i-nickel plating, i-copper plating kanye ne-silver plating.
Ngaphezu kwalokho, inqubo yeI-Sintered Neodymium Magnetsbathambekele izimbobo micro, isakhiwo okuxekethile, surface emangelengele nezinye izici, futhi NdFeb uzibuthe unomphela ekusetshenzisweni imvelo yokusebenza ngokuvamile izinga lokushisa eliphezulu, umswakama eliphezulu.Lezi zinkinga zinikeza izimo ezikahle ze-NdFeb kazibuthe ukugqwala kumazinga okushisa aphezulu kanye nemvelo yomswakama ophezulu.Ngasikhathi sinye, inqubo yokukhiqiza ye-NdFeB kulula ukuqukatha i-O, H, Cl nokunye ukungcola kanye nezinhlanganisela zazo, umphumela olimazayo yi-O ne-Cl izakhi, odonsa kanye ne-O oxidation corrosion, kanye ne-Cl nezinhlanganisela zayo zizosheshisa i-oxidation. inqubo uzibuthe.Izizathu zokugqwala kalula kozibuthe be-NdFeb zibangelwa ikakhulukazi: indawo yokusebenza, ukwakheka kwezinto ezibonakalayo kanye nobuchwepheshe bokukhiqiza.Ucwaningo lubonisa ukuthi ukugqwala NdFeB uzibuthe ikakhulukazi kwenzeka ezindaweni ezintathu ezilandelayo: imvelo efudumele futhi enomswakama, imvelo electrochemical, isikhathi eside izinga lokushisa eliphezulu imvelo endaweni eyomile, lapho izinga lokushisa lingaphansi 150 ℃, izinga oxidation of NdFeb uzibuthe kakhulu. kancane.
