In order to prevent oxidation, magnet manufacturers evaporate a layer of anti-corrosion coating on the surface of NdFeB magnets. The vacuum evaporation device evaporates metal under vacuum conditions, and the evaporated metal forms a thin film on the surface of the permanent NdFeB magnet. The plated metal materials can be gold, silver, copper, iron and zinc, etc. Among them, aluminum is the most commonly used material. Permanent NdFeB magnets can be evaporated in a vacuum environment, and aluminum has very good anti-corrosion properties among metals, so aluminum plating is a coating that has been developed.
