Experimental Investigation on Electroformed Copper-Based Zirconia Nanocomposites Aided by Ultrasonic

To improve the mechanical properties of the EDM electrode material, the electroforming process for fabricating copper-nanozirconia (ZrO2) particles composite aided by ultrasonic has been presented. In this research, some vital process parameters such as concentration of ZrO2, rotational speed and ultrasonic frequency have been evaluated. Two inspection criteria, content of ZrO2 and micro hardness of deposited layer were employed to evaluate the fabrication quality of copper-nanozirconia (ZrO2) composite material. The experimental results indicate that nanocomposites grains electroformed aided by ultrasonic are refined. Their organizations are more uniform and dense, the surface is flatter and the microhardness of nanocomposites is significantly improved.
