摘　　要：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/dm 2 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. 关键词：镍钨合金电镀铜内衬收费异型电流密度能量色散谱仪晶粒尺寸
