Nzira yekudzivirira sei magineti corrosion?

Kuenzaniswa neferrite uye zvimwe zvechigarire magineti, neodymium magineti (NdFeB magineti) ine yakanakisa magineti uye zvakare ndiyo inonyanya kushandiswa isingawanzo pasi magineti. Inoshandiswa zvakanyanya mumagetsi, magetsi emagetsi, midziyo yekurapa, matoyi, kurongedza, hardware michina, aerospace uye mamwe minda. Nekudaro, neodymium magineti (NdFeB magineti) anobatwa zvakanyanya nekuora. Saka sei kudzivirira ngura neodymium magineti? Pane zvinotevera general nzira:
1, Phosphating
Phosphating inzira yemakemikari uye electrochemical reaction kuti igadzire phosphate kemikari inoshandura firimu. Phosphating ine zvinotevera zvinangwa:
1. Chengetedza simbi yepasi kubva pakuora kusvika pamwero wakati.
2. Inoshandiswa seprimer isati yapenda kuti ivandudze kunamatira uye kusagadzikana kwekuora kwefirimu.
3. Inotamba basa rekudzikisa friction uye lubrication mukuita kwesimbi inotonhora kushanda.
2, Electroplating
Electroplating inzira yekuisa mutsetse mutete wemamwe simbi kana alloys pamusoro pemamwe masimbi ne electrolysis. Iyo electroplating process ndeye kushandisa electrolysis kubatanidza pamusoro pesimbi kana zvimwe zvinhu kune simbi firimu, kuitira kudzivirira simbi oxidation (senge corrosion), kunatsiridza kupfeka kuramba, conductivity, kuratidza, corrosion kuramba uye kuwedzera aesthetic maitiro.
3, Electrophoresis
Pasi pechiito chemunda wemagetsi, zvimedu zvinochajiswa zvinoenda kune electrode yakatarisana nemagetsi avo, anonzi electrophoresis. Tekinoroji yekuparadzanisa masheji akachajiswa kuburikidza nemavelocities akasiyana ezvimedu zvinochajiswa mumunda wemagetsi anonzi electrophoresis. Electrophoresis ndeimwe yeaanti-corrosion pamusoro pekurapa matekinoroji anoshandiswa zvakanyanya muSintered Nd-Fe-B uye akasungirirwa Nd-Fe-B magineti echigarire. Iyo electrophoretic coating haingove nekunamira kwakanaka kumusoro kweporous magineti, asiwo ine hunhu hwemunyu wekupfapfaidza, acid uye alkali corrosion resistance.
