摘要
The present disclosure relates to a method for preparing high-performance sintered NdFeB magnets. The method comprises the steps of:a) attaching a multi-element alloy powder onto a surface of the sintered NdFeB magnet, wherein the multi-element alloy is of formula (1) PraRHbGacCud (1)with RH being at least one element selected from Dy and Tb anda, b, c, and d satisfying the conditions 0.30 ≤ (a+b)/(a+b+c+d) ≤ 0.65, 0.20 ≤ d/(c+d) ≤ 0.50, and 0.23 ≤ b/(a+b) ≤ 0.60; andb) performing a diffusion process.
