In this study, electrical discharge coating (EDC) has been performed using green compact electrode of brass and copper powder to fabricate thick coating onto the mild steel substrate. The influence of EDC process parameters on surface morphology, electrode wear, and tribological behavior of coating has been investigated. Experimental result shows fewer pores and micro-cracks on the coated sample with powder mixture ratio of brass:Cu/60:40, peak current of 7A and 70% duty cycle. It is found that the thickness of the coating layer increases with the peak current and the range of the obtained coating layer thickness is 136.19–216.68 µm. The X-ray diffraction profile of coating confirms the presence of elements Cu, CuZn and Fe in the deposited layer. Further, a significant reduction in corrosion resistance and friction coefficient has been observed in the coated sample compared to mild steel substrate.

在这项研究中，使用黄铜和铜粉的生压坯电极进行放电涂层 (EDC)，以在低碳钢基材上制造厚涂层。研究了 EDC 工艺参数对表面形态、电极磨损和涂层摩擦学行为的影响。实验结果表明，黄铜:Cu/60:40的粉末混合比，峰值电流为7A，占空比为70%的涂层样品上的孔隙和微裂纹较少。发现涂层厚度随着峰值电流的增加而增加，得到的涂层厚度范围为136.19-216.68 µm。涂层的 X 射线衍射图证实了沉积层中存在元素 Cu、CuZn 和 Fe。更远，
