Yuav ua li cas kom tsis txhob hlau nplaum corrosion?

Piv nrog ferrite thiab lwm yam khoom siv hlau nplaum ruaj khov, neodymium hlau nplaum (NdFeB hlau nplaum) muaj cov hlau nplaum zoo heev thiab tseem yog cov hlau nplaum uas tsis tshua muaj hauv ntiaj teb. Nws yog dav siv nyob rau hauv electronics, fais fab machinery, khoom kho mob, cov khoom ua si, ntim, hardware machinery, aerospace thiab lwm yam teb. Txawm li cas los xij, cov hlau nplaum neodymium (NdFeB hlau nplaum) yog qhov cuam tshuam rau corrosion. Yog li yuav ua li cas kom tsis txhob xeb ntawm neodymium hlau nplaum? Muaj cov txheej txheem hauv qab no:
1. Phosphating
Phosphating yog cov txheej txheem ntawm cov tshuaj lom neeg thiab cov tshuaj electrochemical los tsim cov tshuaj phosphate hloov dua siab tshiab. Phosphating muaj cov laj thawj hauv qab no:
1. Tiv thaiv lub hauv paus hlau los ntawm corrosion mus rau ib qho twg.
2. Nws yog siv los ua primer ua ntej pleev xim los txhim kho qhov adhesion thiab corrosion kuj ntawm zaj duab xis.
3. Nws plays lub luag hauj lwm ntawm kev sib txhuam txo thiab lubrication nyob rau hauv cov txheej txheem ntawm cov hlau txias ua hauj lwm.
2, Electroplating
Electroplating yog txheej txheem ntawm plating ib txheej nyias ntawm lwm cov hlau los yog alloys ntawm lwm yam hlau los ntawm electrolysis. Cov txheej txheem electroplating yog cov txheej txheem ntawm kev siv electrolysis los txuas cov hlau los yog lwm yam khoom siv rau cov yeeb yaj kiab hlau, txhawm rau tiv thaiv cov hlau oxidation (xws li corrosion), txhim kho hnav tsis kam, conductivity, reflectance, corrosion kuj thiab txhim khu kev zoo nkauj.
3. Electrophoresis
Nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb, them hais tawm mus rau lub electrode opposite rau lawv cov hluav taws xob, uas yog hu ua electrophoresis. Cov cuab yeej ntawm kev sib cais cov khoom siv hluav taws xob sib txawv ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob yog hu ua electrophoresis. Electrophoresis yog ib qho ntawm cov txheej txheem tiv thaiv kev tiv thaiv corrosion saum npoo siv dav hauv sintered Nd-Fe-B thiab sib txuas Nd-Fe-B cov hlau nplaum ruaj khov. Cov txheej txheej electrophoretic tsis tsuas yog muaj qhov zoo adhesion rau saum npoo ntawm cov hlau nplaum ntxeem tau, tab sis kuj muaj cov yam ntxwv ntawm ntsev tsuag, kua qaub thiab alkali corrosion kuj.
