The use of bipolar current pulses in electrospark alloying of metal surfaces

X-ray diffraction analysis of products sintered from isostatically pressed leaded bronze powders

“…To describe the diffraction maximum, a superposition of the Gaussian and Lorentz functions was used. The approximation of each of the reflections in the diffraction patterns of the study samples by the pseudo-Voigt function allowed to accurately determine the position of the reflections taking into account the displacement, caused by overlapping of the reflexes, at half maximum intensity (FWHM) and the intensity [7][8]. The phase composition of the sapmles was identified using the ICCD PDF-2 database (2008).…”

The porosity study of sintered products from electro-erosive materials of alloy Cr13, obtained in butyl alcohol

“…As a result, particles were obtained with an average size of 39 μm. The final porosity of sintered products is influenced by the modes of pressing and sintering [8][9][10][11][12][13][14].…”

X-ray spectral analysis of sintered articles made of electroerosive lead bronze obtained in lighting kerosene

“…As a result of the local impact of short-term electrical discharges between the electrodes, the waste material was destroyed with the formation of dispersed powder particles [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] (Fig.1).…”
