  Causes and Avoiding Methods of Rust in NdFeB Magnet

  NdFeB magnet put a period of time after the surface will appear white or other colors of the spot, slowly developed will become rust, under normal circumstances, the plating magnet coating is not easy to rust, rust causes the following reasons are generally the following:

  1. Magnet stored in the wet, poor air circulation, temperature changes in the place;

  2. The dirt on the surface of the magnet before plating is not well cleaned;

  3. The time of plating is not enough or the process flow problem;

  4. Magnetting of the magnet caused by the sealing of the seal of the magnet;

  NdFeB magnets qualified electroplating products, under normal circumstances, magnet plating plating surface should not appear rust. NdFeB magnets should avoid the following custody:

  In places where the humidity is too wet and the airflow is not good; the temperature difference is large, even if the salt spray test qualified products stored in the harsh environment may produce rust. When the plating products stored in the environment harsh environment, the base layer and further reaction with the condensate, will cause the base layer and the coating of the binding force is reduced, serious will also cause the base of local powder, and then naturally from the skin. Electroplating products should not be placed in high humidity for a long time and should be placed in a cool, dry place.
