摘要：

In this work, copper nanopowder was prepared by utilizing the wire explosion technique in different ambient gas. Ambient gases being used were argon, nitrogen and argon-nitrogen mixture. The ambient gas pressure was 500 mbar. Copper wires with diameter of 125 mu m and length of 6.1 cm were used. The powders being prepared were evaluated by transmission electron microscope (TEM) and X-ray diffractometry (XRD). Current and voltage signals were obtained to investigate the wire explosion process and energy deposition into the wire during the discharge.
