- 論文の詳細を見る
Ni–Cu nanopowders were successfully synthesized from Cu and Ni wires using pulsed wire discharge. The powders were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and energy-dispersive X-ray spectroscopy (EDS). XRD confirmed that the nanopowder produced from Ni and Cu stranded wire was of Ni–Cu alloy. The composition of the nanopowders was controlled by varying the ratio of Ni to Cu wire diameter. TEM showed that the size of the prepared particles was less than 100 nm. EDS results revealed that the compositions of single nanoparticles in the nanopowder were different from each other. The composition distribution indicated that most compositions of nanoparticles agreed with that of the stranded wire. Submicron-sized particles consisting of Ni- or Cu-rich compositions were also found in the sample.
