2. Surface Treatment
Q: Do neodymium magnets require surface treatments?
A: Yes. If magnets are without surface coating (also named plating), it may rust easily under humid conditions.
There have many plating options like Ni-Cu-Ni, Nickel, Zinc, Gold, Black Epoxy, White Epoxy coating and so on.
Zn and Ni-Cu-Ni coating are the most popular coating. The magnet with plating will resist the corrosion effectively.
