We all know that things containing iron are easily oxidized and rusted when exposed to the air or in contact with water for a long time. Like strong magnets, it also contains iron components. Its application environment is also very complex, and at the same time, it has strict requirements on appearance. This requires surface coating treatment to achieve anti-rust and anti-corrosion effects. So what are the functions of neodymium magnet coating?
Magnet plating is generally divided into nickel plating, copper plating, chrome plating, gold plating, zinc plating, blue and white zinc, epoxy resin, etc. The color of the magnet surface will be different depending on the plating, and the long-term storage time will be different. In fact, the role of coating treatment is to protect the strong magnet from being oxidized, making the magnet more resistant to corrosion and salt spray; because the strong magnet itself is gray, sometimes the application may be exposed, and electroplating can make the strong magnet appearance more beautiful, The strong magnet itself is brittle and easy to be bruised and broken. After electroplating, the hardness can also be improved, and it is not easy to be damaged.
