摘　　要：利用感应等离子制备了纳米Cu-30%Ag(质量分数)合金粉,研究原料粉对纳米粉形貌、粒径的影响。结果表明,在感应等离子工艺参数不变条件下,随着原料粉粒径由35.9μm减小至20.1μm和11.3μm,纳米Cu-30%Ag(质量分数)合金粉尺寸逐渐由274 nm细化至105 nm和89 nm,但原料粉对纳米粉的形貌无明显影响。Cu - 30% （mass fraction） Ag alloy nanopowders were prepared by induction plasma system, and the effect of raw materials on size distribution of nanopowders was studied. The results show that with the same processing parameters of induction plasma, the size of the prepared Cu-30Ag alloy nanopowders is refined from 274 nm to 105 nm and then to 89 nm respectively when the different size raw materials of 35.9 um, 20.1 um and 11.3 um are used, and the raw materials have no obvious effect on the morphologies of nanopowders.
