X-Ray Spectral and X-Ray Structural Analysis of Electroerosive Powder Materials from Waste Steel R18

The purpose of this study is to conduct X-ray spectral and X-ray diffraction analysis of the electroerosive charge from waste steel R18.

Methods. To obtain new experimental powder materials (charge) from R18 steel waste, an electroerosive dispersion unit was used. For the study, we used an electroerosive charge from waste steel P18. For X-ray spectral analysis, the method of scanning electron microscopy was used, using an energy-dispersive X-ray analyzer from EDAX, built into a scanning electron microscope "QUANTA 200 3D". X-ray diffraction analysis was performed using a Rigaku Ultima IV diffractometer.

Results. The distribution of chemical elements over the surface of the electroerosive charge from R18 steel waste was experimentally established: carbon, oxygen, molybdenum, vanadium, chromium, iron and tungsten, and the main phases of the charge obtained by electroerosion dispersion from R18 steel waste were determined: WC, Fe₂W₂C, FeV,

Fe₃O₄.

Conclusion. According to the results of the research, it can be concluded that the grinding of waste steel R18 by electroerosion in distilled water leads to the formation of a charge with an elemental and phase composition that allows it to be used as the main material for the production of new tool products, cutting plates, knife blades, and also for the restoration and hardening of tools, parts of automobiles and agricultural machinery, by surfacing, welding and related processes. The obtained results can be used for further research of the electroerosive charge from R18 steel waste.
