Surface treatment of neodymium iron boron magnet, salt spray and corrosion resistance of strong magnetic coating
Many friends who have just touched the magnet may be asked when asking the magnet supplier. What do you want to plate on the surface of your magnet? A look of awkward, because I do not know what is the surface treatment of sintered NdFeB neodymium, the following Carreci magnet Xiao Fu to give popularity.
  1. What are the strong magnetic surface treatment methods for NdFeB neodymium?
  At present, NdFeB neodymium electroplating production mainly adopts three major processes or process combinations of galvanizing, plating "nickel + copper + nickel", plating "nickel + copper + chemical nickel", others such as gold plating, silver plating, tin plating, black nickel plating, Black epoxy and so on.
  2. What is the best plating on the surface of the magnet?
  In fact, this question is very difficult to answer, just like the TV of the same brand, there are 19 inches, 21 inches, which is better? It was the best for myself at the time.
  If there is no special requirement for the magnet, galvanizing is sufficient. If there is a salt spray resistance requirement for the magnet, such as 48 hours, nickel plating is optional.
  3. What colors are available for each plating of the magnet?
  The table below shows the color contrast of each coating on the surface of the magnet.
  Magnet plating color4. What is more resistant to salt spray and more resistant to corrosion?
  The following table shows the evaluation of salt spray resistance, damp heat resistance and corrosion resistance of magnets.
  5. Can NdFeB neodymium not be plated?
  Of course, but it is generally recommended to plate, so the life of the magnet will be longer, usually the case of non-plating is common in the sample, because non-plating can be sampled faster, does not affect the performance, and then do large goods and then electroplating!
