Abstract

Currently, heavy tungsten alloys are widely used in many areas of industry, the most common of them is the alloy W–Ni–Fe 95. This alloy has a very high density and wear resistance, which makes it difficult to process and reuse it. The urgency of recycling this alloy is associated with the presence of expensive alloying components, such as W and Ni, in its composition. One of the most promising methods of grinding any conductive material, regardless of its hardness and other properties, not used in industry is the method of electroerosion dispersion. However, the composition, structure and properties of the particles dispersed by the electroerosion of W–Ni–Fealloy have not been practically studied. To perform the planned studies, the electroerosion dispersion of pseudoalloy chips of W–Ni–Fe95 is performed, for which an electroerosion installation is used to produce metal and alloy powders (RF Patent no. 2 449 859). The waste is placed in the reactor of an electroerosion dispersion installation filled with kerosene. According to the results of experimental studies aimed at carrying out X-ray studies of the surface of the powder obtained by electroerosion dispersion of the waste of pseudoalloy W–Ni–Fe 95 in kerosine, it is established that: the studied powder consists of particles of regular spherical or elliptical shape and irregular shape (agglomerates); the main elements on the surface of the dispersed electroerosion dispersed particles are W, Ni and Fe; the main phases in the electroerosion dispersed particles are W₂C, Ni and Fe.
