【 摘 要 】

The aim of the work is to study the mechanical properties of composite material electrode-tools made of pseudo-alloy of the copper-colloidal graphite system for the Electrical Discharge Machining (EDM) processing of dissimilar materials. Electrode-tools made of copper, graphite and the specific composite material are compared. These electrodes were used for EDM of samples of alloyed steel and tungsten, aluminum and titanium based alloys. After processing, the surface roughness, wear and performance of the tool electrodes were evaluated. As a result of the experiment, it was established that the electrode made of a composite material, copper-colloidal graphite, in some cases, demonstrated significantly higher performance and wear resistance. Based on the data obtained, it was concluded that it is advisable to use an electrode made of a composite material to increase the efficiency of EDM processing of aluminum alloys and alloyed steels, as well as rough EDM processing of titanium alloys.
