Abstract
The results of studying the elemental composition, structure, and physical properties of the copper electroerosion powder material fabricated by electroerosion dispersing (EED) in kerosene from rejects of copper wire of the electrotechnical grade are presented. An original home-made installation (RF Patent No. 2449859) was used for EED of conducting materials. It is established using an Analysette 22 NanoTec laser analyzer that the average size of the powder particle is 33,56 μm. The electron probe microanalysis showed that the content of main elements in powder is 79,5 % Cu, 17,7 % C and 2,0 % O. The results of electron microscopy of studied powder showed that it is constituted by regularly shaped (spherical or elliptical), irregularly shaped (conglomerates) particles, and fragmentary-shaped particles.
