中文摘要：

铜锆 diboride (ZrB_2 ) 合成涂层用脉搏 plating 技术被制作获得 EDM (用机器制造的电镀物品分泌物) 的一种新类型电极材料。脉搏参数的效果，即，平均电流密度，频率和责任骑车，在 ZrB_2 的加入上，在铜矩阵的粒子被调查。代码的 Theamount 安置了 ZrB_2 粒子在 3 A/dm~2 的平均电流密度有最大值并且与减少的责任周期以及为免职使用的脉搏水流的当前的频率增加了。涂层的坚硬与增加 ZrB_2 百分比增加了，而 ZrB_2 粒子的茶碱公司在 composites 的抵抗力上有小效果。

英文摘要：

Copper-zirconium diboride （ZrB2） composite coatings were fabricated using pulse plating technique to acquire a new type of EDM （electro-discharge machining） electrode material. The effects of pulse parameters, i.e., the average current density, the frequency and the duty cycle, on the incorporation of ZrB2 particles in the copper matrix were investigated. The amount＇of codeposited ZrB2 particles had a maximum at average current density of 3 A/din2 and increased with decreasing duty cycle as well as current frequency of the pulse current used for deposition. The hardness of the coatings increased with increasing ZrB2 percentage, whereas the incorporation of ZrB2 particles had little effect on the resistivity of the composites.
