Charge Obtained by Electrodispersing Waste of Alloy H20H80 in Water

The purpose of this study was to study the characteristics of the charge obtained by electrodispersing the waste of the alloy Н20N80 in distilled water.

Methods. Electrodispersion of waste of alloy Н20N80 was carried out in a dispersant. The tasks set in the work were solved using modern equipment and complementary methods of physical materials science, including: the shape and morphology of the particle surface was studied on an electron-ion scanning (scanning) microscope with field electron emission "QUANTA 600 FEG" (Netherlands); the granulometric composition was studied on a laser particle size analyzer "Analysette 22 NanoTec" (Germany); X-ray spectral microanalysis of particles was carried out on an energy dispersive X-ray analyzer of the company "EDAX" (the Netherlands), integrated into a scanning electron microscope "QUANTA 200 3D" (the Netherlands); phase analysis of particles was studied on an X-ray diffractometer "Rigaku Ultima IV" (Japan); the microstructure of particles was studied on an optical inverted microscope "OLYMPUS GX51" (Japan) and an electron-ion scanning (scanning) microscope with a field electron emission "QUANTA 600 FEG" (Netherlands). Results. Based on the conducted experimental studies aimed at studying the composition, structure and properties of the charge obtained from the waste of the alloy X20N80 in distilled water, the high efficiency of the use of electrodispersion technology, which provides, at low energy costs, the production of new nichrome powder materials suitable for industrial use, is shown. It is noted that powder materials obtained by electroerosion of Н20N80 alloy waste in kerosene have the following characteristics: spherical and elliptical particles, agglomerates; particle sizes from 0.25 to 100 microns; the volumetric average diameter of the particles is 34.12 microns; the main elements are Fe, Ni, Cr and C; the main phases are Fe, Ni, Cr and Cr₂О₃.

Conclusion. The conducted research will allow for a gradual transition to advanced production technologies and materials through the use of progressive, environmentally friendly, low-tonnage and waste-free electro dispersion technology for the production of new nichrome powder materials from waste alloy Н20N80 in distilled water.
