Direct Electrodeposition of Cu-Ni-W Alloys for the Liners for Shaped Charges

The Cu-Ni-W alloys for the liners for shaped charges were successfully prepared by direct current (DC) electrodeposition. The influence of cathode current density on morphology, microstructure and composition of the Cu-Ni-W alloys was investigated by means of scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy dispersive spectrometry (EDS). With the increasing of current density, the copper content reduces gradually and the nickel and tungsten content increase; the crystallite size is decreased. When the current density is 15 A/dm2 the tungsten content reaches 12.96 wt pct, and the crystallite size is submicron degree. The Cu-Ni-W alloy is face-centered cubic (fcc) solid solution. All of the Cu-Ni-W alloys take on (220) texture.
