利用感应等离子制备纳米Cu-30%Ag合金粉,研究了等离子气氛中氢气含量对纳米粉形貌、粒径的影响。结果表明,随着等离子气氛中氢气含量的逐渐升高,纳米粉粒径从213 nm减小至151 nm和117 nm,但纳米粉的形貌无明显变化。分析认为纳米粉粒径的变化归功于氢气的引入导致原料粉与等离子能量耦合程度的变化。

Cu-30%Ag alloy nanopowders were prepared by induction plasma system,and the effect of hydrogen content in plasma atmosphere on morphology and size distribution of nanopowders was studied. The results show that with the increase of hydrogen content,the size of the prepared Cu-30%Ag alloy nanopowders is refined from 213 nm to 151 nm and then to 117 nm,however, the morphology of nanopowders has no obvious change. The size refinement of nanopowders results from the introduction of hydrogen,which leads to the change of coupling degree of induction plasma energy.
