摘要:
本文介绍了采用表面活性剂辅助球磨工艺制备永磁纳米材料，主要制备了永磁纳米颗粒、各向异性永磁纳米片、低温制备纳米材料以及“自下而上”技术制备纳米晶块状材料。该方法不仅适用于稀土永磁纳米材料的制备，也可用于软磁纳米片和颗粒的制备。表面活性剂辅助球磨制备的永磁纳米颗粒和片状材料在众多领域具有重要应用。采用 X 射线衍射仪、扫描电子显微镜以及振动样品磁强计等技术研究了不同的表面活性剂辅助球磨工艺对粉体微结构、形貌及磁性能的影响。研究表明，表面活性剂在球磨过程中发挥了重要的作用，改变表面活性剂的种类和工艺条件，不仅能调控粉体的形态，还能控制粉体的磁性能，但该工艺仍存在很多技术难题和理论问题需要进一步的研究。
Abstract:
This paper introduces the surfactant-assisted ball milling which was used to prepare the rare earth permanent magnet nanomaterial. We prepared the nanoparticles、permanent nanoflakes and nanostructured bulks. The rare earth permanent magnet nanomaterial played an important role in different application areas. The effect of milling time and different surfactants on the microstructure、morphology and magnetic properties were studied using the XRD、 FESEM and VSM. It shows that the surfactant played an important role in the milling process. The change of surfactant and the process conditions have an important role in controlling the morphology and magnetic properties of the powders. Finally, there were some the problems of the SABM in recent researches, it deserves further research.
