Wear resistant ring-shaped neodymium iron boron magnet

The Wear resistant ring-shaped neodymium iron boron magnet has extremely high residual magnetic induction intensity and high energy product, which enables it to generate a strong magnetic field in a relatively small volume. Its excellent anti-oxidation and anti-corrosion properties enable it to maintain stable magnetic performance in harsh environments. The annular design not only improves its wear resistance, but also better adapts to various mechanical structures in practical applications. The production process of wear-resistant ring-shaped neodymium iron boron magnets includes steps such as powder metallurgy, sintering, and post-treatment. Firstly, neodymium iron boron alloy powder is prepared by high-temperature smelting and rapid cooling, and then sintered at high temperature to tightly bond its particles and form solid materials with excellent magnetic properties. In the post-treatment process, surface coatings or other protective measures are used to enhance its wear and corrosion resistance.
