Surface treatment for NdFeB
Due to the poor corrosion resistance of neodymium magnets, it is advisable to provide them with a coating. A number of things are important to consider in this regard:
even though ‘stabilized’ neodymium is more resistant to oxidation, the magnet is usually nevertheless coated;
coating NdFeB is a difficult process; only coating companies with specialized knowledge of coating NdFeB are able to achieve good adhesion to neodymium magnets;
NdFeB magnets are also commonly coated with ion vapour deposition (IVD) techniques: the IVD coating process allows precise control of the coating thickness and excellent adhesion of the coating to the material;
in extreme cases it may be desirable to opt for a fully over-moulded plastic version, which ensures that the magnet itself can never come into contact with the air. super stong ring neodymium rare earth magnet
Applications
With their high strength and performance, neodymium magnets are used in many applications, such as:
motors
wind turbines
spindle drives of hard disks
speakers
MRI scanners
magnetic separators
electronics
cars
Often in combination with sensors.
Neodymium magnets have an unlimited number of applications. The exceptional performance of the material has made it invaluable. The strength/weight ratio allows it to be used in ways that were previously inconceivable, allowing present-day engineers to create revolutionary new designs.
