Surface Treatment is Needed for Strong Neodymium(NdFeB) Segment Magnets

The large neodymium arc magnet is a common and powerful magnetic material, known for its high magnetic energy product and excellent corrosion resistance. However, its surface is prone to oxidation, moisture, and wear, which can impact its longevity and performance stability. To address this, surface treatments are employed to enhance its lifespan and stability.

Surface treatments for neodymium arc magnets primarily include methods such as coating, painting, and heat treatment. Among these, coating is a common and effective surface treatment approach. Common coating materials include nickel, zinc, copper, and others. Coating serves to increase the magnet's corrosion resistance, preventing oxidation and moisture erosion, thereby extending its magnetic life.
