NdFeb Magnets are divided into sintered NdFeB and bonded NdFeB. Bonded NdFeB has magnetism in all directions and is corrosion-resistant; while sintered NdFeB is easy to corrode, and the surface needs to be coated, generally galvanized, Nickel, environmental protection zinc, environmental protection nickel, nickel copper nickel, environmental protection nickel copper nickel, etc. Sintered NdFeB is generally divided into axial magnetization and radial magnetization, which are determined according to the required working surface.
With the thawing of sintered NdFeB patented technologies in Japan, Germany, and the European Union, and the concerted efforts of major sintering manufacturers in my country, the grade of sintered NdFeb Magnets has been greatly improved. As a high-tech application field, its comprehensive performance has been continuously improved. The requirements for sintered NdFeB surface treatment have also been greatly improved, and the traditional treatment methods have been unable to meet the requirements of the progress of the industrial chain. University of Electronic Science and Technology of China, Sichuan University, Jiaotong University, Rui Shi Lai and other scientific research institutions, starting from the micro molecular structure. In essence, the principle of surface treatment and the development of industrial application technology have been improved. After 4 years of hard work, breakthroughs in key technologies have been achieved. Nano-chelate film has no coating treatment, which is an original technical process. The active groups contained in the nanofilm layer have strong resistance to moisture, oxygen, chloride ions (Cl), carbon dioxide (CO2), etc. The corrosion resistance and the adhesion of organic resins are greatly improved. Its excellent surface physical and chemical properties are suitable for applications field will have a major impact.
