Sintered NdFeB(neodymium) magnets have the advantages of relatively simple manufacturing process, high magnetic performance and low cost, and are widely used in magnetic separation equipment, MRI equipment, micro-motors, magnetic machinery, communication devices and other fields.
However, the magnetic flux of sintered NdFeB alloys has a relatively large reversible change, and the coercive force will decrease with the increase of temperature. The reduction of the coercive force increases the irreversible loss of the magnetic flux when the magnet works at a relatively high temperature, and the anti-interference force of the external field will also decrease.
In most high-temperature applications of sintered NdFeB permanent magnet materials, stable coercivity is the main reason to limit their application fields. Improving the coercivity is the key to the stability of sintered NdFeB magnets at high temperatures. one of the effective ways. Coercive force is an important performance parameter of sintered NdFeB. It has always been valued by researchers, and good results have been achieved through years of research. In terms of the influence on coercivity, adding alloying elements is also one of the common methods, which mainly determines the magnetic properties of NdFeB. The research in this area is also very thorough.
