NdFeB magnet magnetic material contains a large number of neodymium / iron / boron, easily corroded, it must be coated NdFeB magnet treatment, surface chemical passivation is a very good solution to one of the methods.
NdFeB magnet surface chemical passivation will affect the performance of the original magnet do? Impact be? NdFeB magnets by electroplating nickel-zinc / copper / gold to prevent the magnet itself ten, that is, the air in the water and oxygen corrosion, but the plating layer would reduce the magnetic sheet magnetic strength, but little impact for the application of magnet operating point / Magnetic back curve and performance is not substantially affected.
