Granulometric composition of powders, obtained by electroerosive dispersion of high-chromium steel in kerosene

Abstract

The results of a study of the particle size distribution of powders, obtained by electroerosive dispersion of high-chromium steel in lighting kerosene, are presented. When conducting experiments for electroerosive dispersion, we selected waste from high-chromium corrosion-resistant steel Cr17. Dispersion equipment - experimental setup (RF Patent No. 2449859). Lighting kerosene was used as a working fluid. In order to stabilize the process, dispersion modes were selected experimentally and were as follows: voltage 100 V; pulse repetition rate of 120 Hz; capacitance 48 uF. The particle size distribution of the powders was studied on a Analysette 22 NanoTec laser particle size analyzer. Studies have established that the average particle size obtained is 28.66 µm.
