摘　　要：采用HDDR技术制备NdFeCoAlB各向异性磁粉,研究了添加元素Co、Zr对磁粉性能和磁各向异性的影响。结果表明,磁粉的剩磁(Br)随Co的增加而增加,添加少量Zr基本不改变Br;矫顽力(Hcj)随Co的增加而降低,随Zr的增加先提高后降低;各向异性均随Co、Zr的增加而增大。The technics of HDDR was adopted to prepare anisotropic magnetic powder of NdFeCoAlB alloy.The effects of Co and Ni on the magnetic properties and anisotropy of the HDDR magnetic powder of NdFeCoAlB were studied.It was found that the magnetic remanence of NdFeCoAlB magnetic powder was increased with Co increasing and unchanged basically with Zr increasing.After Zr is added more than 0.1% the coercivity was reduced with Zr increasing,and it＇s reduced with Co increasing.The magneticanisotropy was increased with both Co and Zr increasing.
