摘要
应用电流体动力学技术，采用石英毛细管喷嘴，制备了Ｓｎ－Ｂｉ纳米超微粉，研究了工艺参数对纳米超微粉尺寸的影响．实验结果表明：随着直流高压的增加和毛细管直径的减小．Ｓｎ－Ｂｉ纳米超微粉的尺寸减小，输送熔体的压力对控制纳米超微粉的尺寸也是一个重要影响因素．
The Sn-Bi nanometer powder was prepared by the electrohydrodynamic technique with quartz capillary nozzle. The processing parameters have been investigated.With the increase in DC voltage and the decrease in diameter of capillary nozzle, the particulate size of the Sn-Bi nanometer powder will be reduced. Moreover, the pressure feeding into the molten alloy is also an important factor controlling particulate size.Correspondent YU Xifeng,(Department of Materials Science, Northeastern University, Shenyang 110006)
