Sintering of Cu-TiCN Electrode Materials for Electrical Discharge Machining Process

Electrodes are an important tool in the Electrical Discharge Machine (EDM) production process to produce samples in the desired shape, Produced in large quantities with a smooth surface. There is a low wear and wear rate. In the production of electrodes mixed with other materials and copper. Using the sintering process as another option in the process of producing electrodes. This research studies the production of titanium carbo-nitride (Cu-TiCN) composite electrodes that have been sintered at a temperature of 1,250 “C” using a compression molding force of 22 “Mpa” that affects work efficiency, which has different percentages of ingredients from testing, it was found that a mixture ratio of Cu 80%, Ni 3%, TiCN 17 % is the best ratio for producing electrodes. Has a hardness value of 112.8 “HV” wear-resistant. It has a minimum electrical resistance value of 0.40148 “Ω.cm” a value that allows electric current to flow through it the best. It has a density value of 6. 9 8 “g/cm
³
” indicating good adhesion, resulting in a minimum porosity value of 8.386 %. Along with examination with the SEM process, it was found that there is a strong bond between the molecules that makes them stay together in large groups the most.
