| 摘 要： | 在传统气体雾化的基础上, 提出了一种新型的气体雾化制粉方法, 即在雾化气流中添加NaCl粉末, 提高气流的冲击动量. 通过对6-6-3青铜, Al, Al-Si, Pb, Sn, Zn等多种材料进行的雾化实验结果表明, 该方法能够有效减小雾化粉末的粒度, 与传统气体雾化相比, 平均粒度可减小50%, 此外还可大幅提高细粉收得率, 且不会过多影响粉末的纯度.

| Abstract: | Based on traditional gas atomization, a novel gas atomization method for powder preparation was provided. NaCl powder was added in the flowing gas in order to increase the impact momentum of gas stream. According to the experiments on various materials, including 6 6 3 bronze, Al, Al Si, Pb, Sn, Zn, the results indicate that this novel method is effective in decreasing particle size (compared with traditional gas atomization, the mean particle size is deceased by 50%), increasing the yield of fine powder, while will not deteriorate the purity of the powder. |
