Due to the low corrosion resistance of NdFeB magnets, we need to do surface treatment before applications.
The electroplating flows are as follow:
It may take a complete flow and a long time to do chamfering and cleaning, so electroplating needs a period to proceed.
The available coatings are as follows:
The most popular coatings are Zinc plating, Nickel plating, Epoxy and Passivation, the other coatings are Tin plating, Chromium plating, Gold plating, and Ag plating etc.
