1. What is neodymium magnet coating?

No matter which grade of neodymium magnets, they are hard and very brittle. Since neodymium magnets contain a lot of iron, they need a coating to prevent or slow down oxidation. Otherwise, they will rust, corrode over time and eventually crumble. The coatings available on the market are:

Nickel-Copper-Nickel (Ni-Cu-Ni)
Rubber
Nickel (Ni)
Epoxy
Zinc (Zn)
Gold (Au)
Tin (Sn)
Titanium (Ti)
Titanium Nitride (TiN)
Parylene C
Everlube
Chrome
Polytetrafluoroethylene (PTFE)
Nickel-Copper-Nickel, plus Rubber
Zinc, plus Rubber
Nickel-Copper-Nickel, plus Parylene
Nickel-Copper-Nickel, plus PTFE
Tin, plus Parylene
Zinc chromate
Phosphate passivation
