Abstract
The results of X-ray spectral microanalysis of W-Ni-Fe pseudo-alloy, obtained from electroerosive powders, are presented. Consolidation of the obtained electroerosive powders was carried out by the method of spark plasma sintering using the SPS 25-10 spark plasma sintering system. Using an EDAX energy-dispersive X-ray analyzer built into a Quanta 600 FEG scanning electron microscope, characteristic X-ray spectra were obtained at various points on the sample surface and along a transverse section. As a result of the study, it was found that on the surface of the investigated sintered sample, tungsten, nickel and iron are contained as the main elements, and oxygen, copper and chromium are also present in small amounts.

Pseudo-alloys W-Ni-Fe are widely used in industry, and as a result, there is a problem with the processing of their waste and reuse [1-8].The existing technologies for the production of W-Ni-Fe alloys are characterized by large tonnage, energy intensity, large production areas, low productivity, and environmental problems
Carrying out the planned measures will allow solving the problem of waste disposal and their further use and thereby reduce the cost of the final product
Summary
Pseudo-alloys W-Ni-Fe are widely used in industry, and as a result, there is a problem with the processing of their waste and reuse [1-8]. One of the most promising methods of disposal of almost any electrically conductive material, including the W-Ni-Fe alloy, characterized by relatively low energy consumption and environmental friendliness of the process, is the method of electroerosive dispersion (EED) [9-11]. The relevance of the work is determined by the important economic task of creating progressive, environmentally friendly, energy-saving and waste-free technologies for producing powders, including nanoscale ones, and their practical application. Complex theoretical and experimental studies are required to develop technologies for producing products from powders, obtained from W-Ni-Fe wastes and to assess the efficiency of their use. The EED method is one of the promising methods for producing powders from almost any conductive material, including from ball-bearing steel waste, and is characterized by relatively low energy consumption and environmental friendliness of the process [12-18]. Carrying out the planned measures will allow solving the problem of waste disposal and their further use and thereby reduce the cost of the final product
