Effect of Hydrogen on Size of Cu-Ag Alloy Nanopowders

Abstract:

Cu-30wt%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-30wt%Ag alloy nanopowders is refined from 213 nm to 151 nm and then to 117 nm, however, there is no obvious effect on the morphology of nanopowders. The variation of nanopowders size should be attributed to the introduction of hydrogen, which leads to the change of energy coupling degree between starting powder and induction plasma.
