Xinfeng's experiments yakaratidza kuti cubic centimita yeSintered NdFeb Magnetyaizosvibiswa neoxidation mushure mekuratidzwa kumhepo pa150 ℃ kwemazuva 51.Inoora zviri nyore mune isina simba asidhi mhinduro.Kuti iite kuti NdFeb Permanent Magnet igare yakasimba, inofanirwa kuve ne20-30 yemakore ehupenyu hwesevhisi, inofanirwa kurapwa pamusoro pecorrosion kurapwa, kuitira kuti irambe kusvibiswa kwepakati pemagineti.Uye inowanzonziElectroplating Permanent Magnet.
Parizvino, sintered NdFeb yekusingaperi magineti system yekugadzira indasitiri inowanzo tora electroplating simbi, electroplating + kemikari goridhe-plating, electrophoretic coating uye phosphating kurapwa, nezvimwewo, pamusoro pemagineti yakaputirwa neimwe dhizaini yekuzviparadzanisa nevamwe, iyo magineti pamusoro uye. iyo inopisa mukati inoparadzaniswa, kuitira kudzivirira kukanganisa kwepakati kusvika kune magineti.
1.Generally galvanized, nickel + copper + nickel, nickel + copper + electroless nickel plating matatu maitiro, mamwe simbi plating zvinodiwa, kazhinji mu nickel plating uye ipapo mamwe simbi plating.
2.Muzvimwe zviitiko zvakakosha zvichashandisawo phosphating
1) MuNdFeb magineti zvigadzirwa nekuda kwekuchinja, nguva yekuchengetedza yakarebesa uye isina kujeka yekutevera nzira yekurapa pamusoro, kushandisa phosphating iri nyore uye iri nyore;(2) Kana magineti ichida epoxy adhesive, pendi, glue, pendi uye imwe epoxy organic bonding simba inoda iyo substrate kuti ive nekuita kwakanaka kwekupinda.Phosphating process inogona kuvandudza kugona kwekupinda kwemagineti pamusoro.
3.Electrophoretic coating yakava imwe yeinonyanya kushandiswa anti-corrosion surface treatment techniques.Nekuti haina chete yakanaka yekubatanidza simba nepamusoro peporous magineti, asiwo ine corrosion resistance yemunyu wekupfapfaidza, asidhi uye alkali, nezvimwewo, yakanakisa corrosion resistance.Asi kana zvichienzaniswa nekupfapfaidza kupfapfaidza, kuramba kwayo kupisa uye hunyoro hakuna kunaka.
Vatengi vanogona kusarudza coating maererano nechigadzirwa chebasa ravo zvinodiwa.Nekuwedzera kwekushandisa mota, vatengi vane zvinodiwa zvepamusoro zveNdFeb corrosion resistance, uyeHigh Quality Electroplating Permanent Magnetzvinodiwa.Iyo HAST kuyedza (PCT kuyedza) yakagadzirirwa kuyedza kuramba kwecorrosion yeSintered NdFeb magineti echigarire munzvimbo dzakanyorova uye dzakanyanya tembiricha.
Vatengi vanoona sei kana iyo coating inosangana nezvinodiwa?Kuyedza kupfapfaidza munyu ndicho chinangwa chepamusoro peiyo anti-corrosion coating yakabatwa sintered NdFeb magineti kuita kukurumidza anti-corrosion kuyedza, pakupera kwekuyedza, sampuli kubva mubhokisi rekuyedza, rakaoma, nemeso kana girazi rinokudza tarisa nzvimbo yemuenzaniso ine mavara, mavara ehukuru hwebhokisi ruvara runoshanduka.
Kupfupisa, chete nekunzwisisa maitiro ekugadzira uye zvinodikanwa zvechigadzirwa zvinogona mutengi kutonga nemazvo kuenderana kwechigadzirwa.Muchidimbu, ndiko kubata kwekuita, kutonga kwekushivirira kwedimensional, kuona kwekuputira uye kuongororwa kwechitarisiko.
Panyaya yekuita, Br (residual magnetism), Hcb (kumanikidza), Hcj (mukati coercivity), (BH) Max (yakanyanya magineti simba chigadzirwa) uye demagnetization curve inogona kuwonekwa nekuita.Dimensional kushivirira, iko kurongeka kunogona kuyerwa nevernier calipers;Pakupfekedza, ruvara uye kupenya kwejasi rinogona kucherechedzwa neziso rakashama uye rinoonekwa nekusunga simba uye munyu wekupfapfaidza bvunzo.Chitarisiko chakazara, kunyanya neziso rakashama kana girazi rinokudza, kana microscope yemaziso (yemutsara wechigadzirwa isingasviki 0.2mm), pamusoro pemagineti yakatsetseka, hapana zvidimbu zvinooneka uye miviri yekunze, hapana mavara, hapana inodonha kona inodonha, chitarisiko chinokodzera.
