Painting, coating, or plating is generally recommended for NdFeB, although recently certain grades have been made that exhibit higher resistance to oxidation. Plating NdFeB is a difficult process, and commercial plating houses unfamiliar with the specialized plating techniques required are unlikely to be able to achieve plating with good adhesion on Neo magnets. Nickel, Zinc, or Tin plating, plating provides good corrosion resistance for NdFeB magnets, though longer lead times or higher volumes may be required for these. We are also able to cadmium chromate or aluminum chromate plate NdFeB using ion vacuum deposition (IVD) techniques. A variety of organic coatings have also been successfully developed for NdFeB, exhibiting good corrosion resistance characteristics. For especially harsh environments, it may be advisable to use a combination of coating techniques, or to encapsulate the material in a sealed housing.
