Production and research of Nickel powders by grinding metal waste of Nickel grade PNK-0T1 in kerosene

Purpose . Production and research of nickel powders by grinding metal waste of nickel grade PNK-0T1 in kerosene. Methods . Nickel powder from PNK-0T1 nickel metal waste in aviation kerosene of the TS-1 brand was obtained with the following electrical parameters of the installation: capacitance of capacitors 44.0-45.5 pF; electrode voltage from 115-120 V; pulse repetition frequency 60-65 Hz. The resulting nickel powder was examined by various methods. Microanalysis of powder particles was carried out using a scanning electron microscope QUANTA 600 FEG. The analysis of the size distribution of powder particles was obtained using the particle size analyzer Analysette 22 NanoTec. The X-ray spectral microanalysis of the powder particles was carried out using an energy dispersive X-ray analyzer from the EDAX company, integrated into a scanning electron microscope QUANTA 600 FEG. Results . Based on the conducted experimental studies, a new method for producing nickel powder has been devel-oped, characterized in that the powder is obtained by electroerosive dispersion of nickel metal residues of the PNK- 0T1 brand in aviation kerosene of the TS-1 brand with a capacitance of 44.5 UF capacitors, an electrode voltage of 120 V and a pulse frequency of 65 Hz, which provides, at low energy costs, the production of new nickel powder materials suitable for industrial use. It has been experimentally established that the shape of the particles of the ob-tained nickel powders is mainly spherical and elliptical. Carbon is present on the surface of nickel particles. The phases of α-modification nickel and β-modification nickel are marked in the phase composition of the particles. Conclusion . The conducted research will make it possible to select the most rational field of practical application of the electroerosive nickel powder.
