将Fe78Si9B13非晶态粒子应用于硅油基磁流变液的制备。用X射线衍射仪和扫描电子显微镜对Fe78Si9B13非晶颗粒的结构和形貌进行了表征。用振动样品磁强计对Fe78Si9B13非晶态粒子及其磁流变液的磁性能进行了表征。用旋转流变仪研究了磁流变液的磁流变效应。结果表明，Fe78Si9B13非晶颗粒的饱和磁化强度为169.48 emu g−1，具有较低的剩磁和较低的矫顽力。旋转流变学结果表明，在外加磁场下，含有Fe78Si9B13非晶态颗粒的磁流变液比含有纳米Fe3O4颗粒的磁流体具有更好的磁流变响应。
Fe78Si9B13 amorphous particles are applied in the preparation of silicon oil-based magnetorheological (MR) fluids. The structure and morphology of the Fe78Si9B13 amorphous particles were characterized by X-ray diffraction and scanning electron microscopy, respectively. The magnetic properties of the Fe78Si9B13 amorphous particles and the MR fluids prepared with Fe78Si9B13 amorphous particles were characterized by vibrating sample magnetometry. The MR effect of the MR fluids was investigated with a rotational rheometer. The results of VSM show that the saturation magnetization of Fe78Si9B13 amorphous particles is 169.48 emu g−1, accompanying low remanence and low coercivity. The results of rotational rheometry manifest that the MR fluids with Fe78Si9B13 amorphous particles have an improved magnetorheological response compared with magnetic fluids with Fe3O4 nanoparticles under an applied magnetic field.
