摘要
A method for improvement of magnetic performance of sintered NdFeB magnet includes the following steps. Firstly, material containing element R, H and X is to be covered on a surface of the sintered NdFeB magnet to form a finish coat. After that, proceed with a diffusion treatment and an aging treatment to the sintered NdFeB magnet with the finish coat in the environment of vacuum or inert gas. R is at least one of such elements as Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu. H is hydrogen. X is at least one of such elements as C, O, N, S, B, Cl and Si.
