The wide use of the EED method for processing metal waste into powders for the purpose of their reuse and application in additive technologies is hampered by the lack in the scientific and technical literature of full-fledged information on the effect of the initial composition, regimes and media on the properties of powders and technologies of practical application. Therefore, in order to develop technologies for the reuse of electroerosive powders and to evaluate the effectiveness of their use, complex theoretical and experimental studies are required. The aim of the work was to conduct X-ray spectral microanalysis of additive products from electroerosive cobalt-chrome powders. For the implementation of the planned studies, wastes of the cobaltochrome alloy of the brand KHMS “CELLIT” were chosen. As a working fluid, butyl alcohol (butanol-1) was used. For the production of cobalt-chrome powders, a unit for EED of conductive materials was used. Dispersion parameters: voltage 100 V, capacity 48 μF, repetition rate 120 Hz. The microstructure of the samples (on the surface) was studied by scanning electron microscopy. The surface of the samples was ground and polished. With the help of an energy-dispersive X-ray analyzer from EDAX, built into the scanning electron microscope QUANTA 200 3D, spectra of characteristic X-ray radiation were obtained at various points on the surface of the sample and along the cross-section. Based on the results of X-ray spectral analysis of additive products from electroerosive cobalt-chrome powders, it has been established experimentally that the main elements in them are Co, Mo, and Cr.
