Common Coatings Rau Neodymium Magnets

NdFeB (neodymium hlau boron) hlau nplaum yog ib hom ntawm lub ntiaj teb tsis tshua muaj hlau nplaum uas paub txog lawv lub zog tshwj xeeb thiab cov khoom sib nqus. Txhawm rau tiv thaiv NdFeB hlau nplaum los ntawm corrosion thiab puas, lawv feem ntau coated nrog cov khoom sib txawv.
Nov yog qee hom txheej txheej siv rau NdFeB hlau nplaum, nrog rau lawv qhov zoo thiab qhov tsis zoo:

 

Nickel (Ni) Txheej:
Qhov zoo:
1.Provides zoo heev tiv thaiv corrosion thiab oxidation.
2.Enhances lub zog txhua yam ntawm cov hlau nplaum.
3.Yuav tau yooj yim plated rau saum npoo ntawm cov hlau nplaum.

Qhov tsis zoo:
1.Nickel txheej tuaj yeem ua rau chipping thiab flaking dhau sijhawm.
2.Nickel yog cov khoom sib nqus, uas tuaj yeem cuam tshuam rau qee qhov kev siv uas yuav tsum tau muaj cov txheej txheem tsis sib nqus.

 

Epoxy txheej:
Qhov zoo:
1.Muaj kev tiv thaiv zoo heev tiv thaiv ya raws, av noo, thiab lwm yam ib puag ncig.
2. tuaj yeem ua raws li cov xim tshwj xeeb thiab tuab.
3.Provides zoo rwb thaiv tsev rau cov hlau nplaum.

Qhov tsis zoo:
1.Tej zaum yuav tsis zoo li lwm cov ntaub ntawv txheej.
2.Epoxy tuaj yeem ua nkig dhau sijhawm thiab tuaj yeem tawg thaum muaj kev ntxhov siab.

 

Zinc (Zn) Txheej:
Qhov zoo:
1.Provides zoo corrosion kuj ntawm tus nqi qis dua npib tsib xee.
2. tuaj yeem siv rau ntau yam thicknesses.
3.Non-magnetic txheej.

Qhov tsis zoo:
1.Zinc txheej tej zaum yuav tsis zoo li lwm yam ntaub ntawv thiab yuav hnav tam sim ntawd.
2.Zinc tej zaum yuav tsis muab ntau npaum li kev tiv thaiv tiv thaiv qee yam tshuaj.

 

Kub (Au) Txheej:
Qhov zoo:
1.Provides zoo heev tiv thaiv oxidation thiab corrosion.
2.Txhim kho qhov zoo nkauj ntawm cov hlau nplaum.
3.Non-magnetic txheej.

Qhov tsis zoo:

1.Gold txheej tuaj yeem kim piv rau lwm cov txheej txheem.
2.Tej zaum tsis muaj kev tiv thaiv ntau npaum li qee cov tshuaj ib yam li lwm cov ntaub ntawv.

 

Zuag qhia tag nrho, kev xaiv txheej rau NdFeB hlau nplaum nyob ntawm daim ntawv thov tshwj xeeb thiab ib puag ncig uas yuav siv cov hlau nplaum. Nws yog ib qho tseem ceeb uas yuav tsum xav txog yam xws li tus nqi, kev ua haujlwm ntev, thiab kev tiv thaiv corrosion thiab lwm yam ib puag ncig thaum xaiv cov txheej rau NdFeB hlau nplaum.
