Reasons for rust spots on customized neodymium magnets n35 and how to avoid them
After putting customized neodymium magnets n35 for a period of time, there will be milky white or other color pigment spots on the surface, and it will gradually develop into rust spots.
After putting customized neodymium magnets n35 for a period of time, there will be milky white or other color pigment spots on the surface, and it will gradually develop into rust spots. Generally, neodymium iron boron magnets will develop electroplated magnet coatings under normal circumstances to make it difficult to produce rust spots. The reasons for rust spots are generally the following types of reasons:
1. The customized neodymium magnets n35 are stored in humid areas with poor natural ventilation and varying temperature differences;
2. For customized neodymium magnets n35 before electroplating, the dirt on the magnet surface is not cleaned and cleaned, and then the actual coating operation will be carried out;
3. The electroplating time of customized neodymium magnets n35 is not enough or the production process is difficult;
4. Magnet oxidation caused by the destruction of the packaging of customized neodymium magnets n35;
For customized neodymium magnets n35 standard electroplated products, under all normal conditions, no rust spots can be produced on the electroplated surface of the magnet. NdFeB magnets should avoid the following storage methods:
In areas with excessive humidity and poor natural ventilation; when the temperature difference is very large, even products that meet the salt spray test standards for long-term storage in harsh environments are likely to cause rust spots. When electroplating products are stored in a harsh geographic environment, the subcutaneous tissue will be further reflected in the condensed water, which will cause the subcutaneous tissue and the plating layer to reduce the fusion, and in more serious cases, it will continue to cause part of the wall or material delamination again, and then Molt naturally. The customized neodymium magnets n35 cannot be placed in areas with high relative humidity for a long time, but should be placed in a cool, dry area.
