Corrosion Prevention Methods for Strong Magnets

Anti corrosion technology is widely used in many fields, including in the field of magnets, as powerful magnets are very easy to corrode. Therefore, most manufactured products must be electroplated or sprayed. The basic surface treatment includes electroplating nickel (nickel copper nickel), hot dip galvanizing, aluminum coating, electrophoresis principle, etc. If working in a fully enclosed natural environment, phosphating treatment can also be applied.
NdFeB is a widely used and rapidly developing magnet product. Strong magnets have been widely used since their creation and invention, but they have been in use for no more than 20 years. Due to its high magnetism and easy processing performance, the price is not very high, so its main use has rapidly expanded. At present, the commercial neodymium iron boron powerful magnet can achieve a magnetic energy product of 500000 kilowatts, which is 10 times that of ferrite.
Compared with other permanent magnet ferrite materials such as ferrite, powerful magnets have excellent magnetic properties. Its electromagnetic energy products are much higher than other types of magnets, so it can be called the "first generation magnet king". Strong magnets have a very high saturation state coercivity BS (BS=16KGS) and various fields of magnetic crystallization HA (HA=73KOE). Neodymium magnet products are widely used in packaging, small toys, gifts and artworks, sports and fitness magnetic control cars, electric motors, micro motors, electronic computers, instrument equipment, instrument panels, motorcycles, digital cameras, clocks, sounds, electrical products, office systems, far-infrared magnetic therapy, and various industries in daily life.
Strong magnets also belong to powder metallurgy products, and their production and processing methods are similar to samarium cobalt. At present, the maximum operating temperature of a powerful magnet is approximately 180 degrees Celsius. In severe natural environment applications, it is generally recommended not to exceed 140 degrees Celsius.
This is the strong magnetic anti-corrosion technology that everyone has explained in detail. Due to its high magnetism, powerful magnets are used in many places to replace other magnetic raw materials to reduce the volume of products. If ferrite magnets were used, the current screen size might not be easily lower than half a brick.
