Types of Coatings                                                                                                                          
The coatigns can be divided into two basic groups: metallic and organic. to meet special requirements and on request, double coatings of metal/metal, metal/varnish and a number of special coatings are available

Metallic coatings

Usually, galvanic processes are used for metallic coating.we have

…Zinc coatings (blue passivated or yellow passivated )

…Nickel + Nickel coating

…Nickel + Tin coating

…Nickel + Copper + Nickel coating (available starting from June,1998)

 

Organic coatings

…Nickel + Epoxy coating

…Epoxy coating

Temporary corrosion protection /Surface Passivation

To protect uncoated magnets temporarily, e. g., during transport or storage, Passivation can be made. This protects NdFeB magnets sufficiently against temporary environmental influences, such as a rise in humidity. With this special treatment, magnets can be stored under normal ambient conditions.

Passivated magnets is not suitable to be installed into system without further treament
