  How to detect the coating quality of NdFeB magnets?

 

  The quality of the coating directly affects the service life of the NdFeB magnet. The main methods for testing the coating quality of the NdFeB magnet are as follows:

 

  1. Visually inspect the appearance of neodymium iron boron magnets

 

  The appearance is mainly observed by the naked eye, and it is best under natural light (daylight, non-direct sunlight), or under a fluorescent lamp with an illuminance equivalent to 40W. There should be no blistering, peeling, partial failure of plating, uneven color tone, stains, water stains, etc.

  2. To measure the thickness of the NdFeB magnet coating

 

  3. Conduct drop test on the coating of NdFeB magnet (mainly for galvanized products)

 

  4. Cross-cut test for the coating of neodymium iron boron magnets (usually used for nickel-plated products)

 

  5. Carry out chilling and heating test for the coating of neodymium iron boron magnets

 

  6. PCT pressure test for NdFeB magnet coating

 

  7. SST salt spray test for NdFeB magnet coating

 

  8. Conduct constant temperature and humidity test for the coating of neodymium iron boron magnets, etc.
