Abstract

The aim of work is to compare powder materials for producing different types of electrodes processed by powder metallurgy and electrophoretic erosion processes. The three types of electrode materials consist of Copper (Cu) electrode materials, copper-titanium nitride (Cu-TiN) electrode material, and copper-titanium carbonitride (Cu-TiCN) electrode material were all samples into a sintering process at 1050 °C. For experiments by adjusting the current parameters. It was found that only the electric current affects the work efficiency and surface quality of the samples. This experiment started with a current of 9, 15, 25 Amp, which at 9 Amp gave the lowest average surface roughness. This resulted in a maximum removal rate of 0.0047 g/min of copper-titanium nitride (Cu-TiN) electrode material, and consequently, the electrode wear rate was higher. The lowest surface roughness was 33.7209%, as well as the results of the surface roughness experiment, the lowest mean surface roughness was 9.3 µm.
