Neodymium Iron Boron magnets are vulnerable to corrosion and consideration should be given to the operating environment in order to determine if coating is necessary. Under circumstances where corrosion is likely, the magnets can be protected with metal or epoxy coatings.
Neorem Ningbo has a fully automatic Ni-coating line, which has been imported from Finland. By combining advanced equipment and optimal process parameters¡¯ control, superior quality of Ni-coating is achieved. After coating the layer thickness and adhesion between the magnet and the coating are controlled in each batch by an optical microscope. In our Ni-coating the adhesion is superior and also gives better gluing properties than conventional bright Ni-coating. |
