Iyo kemikari yekudzivirira tekinoroji yeNdfeb Neodymium Magnetkunyanya zvinosanganisira electroplating uye electroless plating pamusoro simbi coatings, shanduko firimu zvedongo coatings uye spraying uye electrophoresis pamusoro Organic coatings.Mukugadzira, inowanzo shandiswa kugadzirira simbi inodzivirira yekuvhara pamusoro peNdFeb magineti ne electroplating process.Electroplating inzira iyo iyo magineti workpiece inoshandiswa se cathode uye simbi cation mu electroplating mhinduro inoderedzwa pamusoro pemagineti nekushandisa kunze ikozvino kugadzira simbi coating.Kudzivirirwa kwe electroplating kweSintered Neodymium Magnetszvinonyanya kuvandudza corrosion resistance yemagineti, pamwe nekuvandudza nzvimbo yemechanical zvivakwa uye kushongedza.
Mushure memakore ekugadzirwa uye kushandiswa, kukanganisa kweNdFeb magnet electroplating protective coating zvakare zviri pachena: Iyo porosity yejasi yakakura, iyo yekupfeka haina kukora, uye ine chimiro kushivirira.Iko kona ye workpiece ichave yakakora nekuda kwekusangana kwetambo yemagetsi mu electroplating process, saka kona yeRare Earth Permanent Magnetinofanira kucheneswa, uye sampuli yegomba rakadzika haigone kuputirwa.Electroplating process ine zvinokuvadza pane magineti matrix.Mune dzimwe nguva dzakaoma, mushure mokunge electroplating coating yakashandiswa kwenguva yakareba, kuvhara kuchaonekwa kunoputika, kusvuura, nyore kudonha uye mamwe matambudziko, uye kushanda kwekudzivirira kuchaderera.Nekuvandudzwa kwekuziva kwezvakatipoteredza, chikamu chemutengo wakakwana we electroplating matatu emarara ekurapa unowedzera zvakanyanya.
Neodymium Electromagnetnickel plating tekinoroji inoreva iyo REDOX maitiro esimbi munyu uye inodzikisa mumiririri mubhavhu pasina kuwedzera kweiyo yakashandiswa ikozvino.Pasi peiyo catalytic chiito cheiyo workpiece pamusoro, maitiro esimbi ion kuderedza deposition.Kuenzaniswa ne electroplating, electroless plating process midziyo iri nyore, haidi simba uye yekubatsira electrode, coating ukobvu yunifomu, kunyanya yakakodzera chimiro cheyakaomesesa workpiece, yakadzika gomba zvikamu, pombi yemukati madziro emadziro plating, density uye kuoma kwekupfeka. yakakwirira.Electroless plating inewo zvimwe zvikanganiso, iyo yekuvhara ukobvu haikwire, inogona kupfekwa zvakasiyana-siyana haisi yakawanda, zvinodiwa zvemaitiro zvakanyanyisa, kuchengetedza kwekugezera kwakanyanya kuoma.Chemical plating inonyanya nickel plating, copper plating uye sirivheri.
Mukuwedzera, nzira yeSintered Neodymium Magnetsvane diki makomba, yakasununguka chimiro, rough pamusoro uye kumwe kukanganisa, uye NdFeb zvachose magineti mukushandiswa kwenzvimbo yekushanda kazhinji tembiricha yakakwira, humidity yakakwira.Aya akaremara anopa mamiriro akaringana eNdFeb magineti corrosion mukupisa kwakanyanya uye yakakwirira humidity nharaunda.Panguva imwecheteyo, iyo nzira yekugadzira yeNdFeB iri nyore kuve neO, H, Cl uye mamwe matsvina nemakomponi awo, iyo corrosive mhedzisiro ndeye O uye Cl zvinhu, magineti uye O oxidation corrosion, uye Cl nemakomisheni ayo anomhanyisa oxidation. nzira yemagineti.Zvikonzero zvekuora kuri nyore kweNdFeb magineti zvinonyanya kukonzerwa ne: nharaunda yekushanda, chimiro chemidziyo uye tekinoroji yekugadzira.Tsvagiridzo inoratidza kuti ngura yeNdFeB magineti inowanzoitika munzvimbo nhatu dzinotevera: inodziya uye ine hunyoro nharaunda, electrochemical nharaunda, yakareba tembiricha nharaunda munzvimbo yakaoma, kana tembiricha yakadzikira kupfuura 150 ℃, iyo oxidation mwero weNdFeb magineti yakanyanya. slow.
