This paper presents the surface modification of aluminium-6061 by electric discharge machining (EDM). Si–Cu powder metallurgical green compact tool is used to deposit its material on to the work surface under reverse polarity of EDM. Compact load, current and pulse on-time are selected control parameters. Material deposition rate (MDR), tool wear rate (TWR) and surface roughness ($R_a)$ are considered as process outputs. Scanning electron microscopic (SEM) analysis and energy dispersive X-ray (EDX) analysis show the presence of tool materials in the deposit of work surface. Olympus optical micrograph shows an average thickness of the deposited layer to be 18.73$$$\mu$m. The hardness of the deposited layer is found to be 268$$HV. Analysis of variance (ANOVA) shows the compact load to be the most effective parameter on surface modification followed by pulse on-time and current, respectively.

本文介绍了通过放电加工（EDM）对铝6061进行表面改性的方法。Si-Cu粉末冶金生坯工具用于在EDM的反极性下将其材料沉积到工作表面上。紧凑的负载，电流和脉冲导通时间是选择的控制参数。材料沉积率（MDR），工具磨损率（TWR）和表面粗糙度（${\mathrm{[R}}_{\mathrm{一种}}）$被视为过程输出。扫描电子显微镜（SEM）分析和能量色散X射线（EDX）分析表明，工作表面沉积物中存在工具材料。奥林巴斯光学显微照片显示，沉积层的平均厚度为18.73$$$\mu$米 发现沉积层的硬度为268$$高压 方差分析（ANOVA）表明，紧凑型负载是表面改性最有效的参数，其次是脉冲导通时间和电流。
