Abstract

The purpose of this work was to study the morphology and particle size distribution of new tungsten-free hard-alloy powder materials produced by electro erosive dispersion in an oxygen-containing medium (distilled water). To produce new tungsten-free hard-alloy powder materials, an experimental laboratory setup for electro erosive dispersion was used. The analysis of the grain size composition of electro erosive tungsten-free hard-alloy particles was carried out by means of an Analysette 22 Nano Tec laser particle size analyzer. The method of scanning electron microscopy using a QUANTA 600 FEG microscope was used to study the morphology of the experimental powder material. The results of the analysis of the particle size distribution of electro erosive tungsten-free hard-alloy particles showed that the particle size ranges from 0.372 µm to 65.5 µm. It is shown that the average size of the particles obtained in distilled water is 41.63 μm. The study of morphology showed that in the process of electro dispersion of metal waste, the particles that ejected from the electric discharge channel in molten form crystallized very quickly. The process of rapid crystallization of the molten material in a liquid working medium contributes to the formation of particles of the correct spherical and elliptical shape.
