Guys! Today, let‘s talk about the corrosion resistance of Ndfeb magnets!
Ndfeb magnet has the title of "magnetic king", its magnetic performance is strong, and it has important applications in many fields, such as our common electronic products, audio equipment, new energy vehicles, and so on.
However, the corrosion resistance of Ndfeb magnets is a bit worrying. This is because its main composition of iron is relatively large, and iron is easy to oxidize with oxygen in the air, coupled with rare earth elements such as neodymium itself is relatively lively, so once it encounters water, acid and alkali and other substances, the surface of the Neodymium iron boron magnet is easy to be corroded, rust and other situations, thus affecting its performance and service life.
Moreover, there are grain boundaries and phase boundaries in the crystal structure of Ndfeb magnets, which are like "weak links", providing an intrusion channel for the corrosive medium, making the corrosion process easier to occur and accelerate.
But don‘t worry, scientists have figured out a way to solve this problem. It is usually used to electroplate nickel, zinc and other metals, or coated with organic coating, to put on a layer of "protective clothing" to the Ndfeb magnet, so that it can effectively insulate the external corrosive medium, greatly improve its corrosion resistance, so that it can play a better role.
