“…To obtain electroerosive materials, waste steel X13 was loaded into the reactor of the electroerosive dispersion unit, filled with a working fluid -butyl alcohol. In this case, the following parameters of the installation were used: -pulse repetition rate 95 ... 105 Hz;voltage at the electrodes 100 ... 110 V; -the capacitance of the capacitors is 55 μF [7][8][9][10]. As a result of electric spark discharges, dispersed particles were formed in the contact zone of the electrodes and with the dispersed waste material, which was then subjected to pressing and sintering.…”

“…Therefore, there is an acute problem of recycling chromium-containing steel waste into powders suitable for practical use. The most promising method for processing such wastes is the electro-erosion dispersion method (EED), which is distinguished by the ecological purity of the process and relatively low energy costs [7][8][9][10].…”

Chromium is the most common alloying element. Chromium alloyed steel has increased strength, hardness, wear resistance, corrosion resistance in aggressive and oxidizing environments. The process of obtaining powder materials by the method of electroerosion dispersion favorably differs by the possibility of obtaining powders even from very hard and refractory materials. In the case of grinding material with this method, the only important criterion is the electrical conductivity of the material being ground. Worn parts and other scrap can be used as feedstock during the process. The purpose of the study is to investigate the powder, obtained from the waste of chromium-containing steels. Thanks to the study of the used powder samples on modern devices, results were obtained indicating that the chromium powder obtained by the method of electroerosive dispersion can be reused to restore and strengthen the machine parts.

“…Using powder metallurgy methods, it is possible to create materials from various components with sharply differing properties and melting points, new materials with a diverse set of physicomechanical properties. Powder metallurgy is used both to create fundamentally new materials and products from them, and to manufacture the widest range of structural parts for general purposes [1][2][3][4][5][6].…”

The results of graphic information processing and investigation of the microhardness of the sintered sample from chromiumcontaining waste are presented. Currently, one of the main directions of development of engineering technology is the improvement of existing and the development of new waste-free, environmentally friendly, material-saving production processes. Powder metallurgy is a branch of technology, including the manufacture ofpowders from metals and their alloys and the preparation of blanks and products from them without melting the main component. In most cases, new materials are created in order to provide the optimal combination ofproduct price and operational characteristics. Microhardness is the resistance to plastic indentation (usually on a flat surface) of a solid tip in the shape of a cone or a pyramid made of diamond. With the help of microhardness, they control very small parts, test and sort out watch, instrument and other products. The aim of the work was to study the microhardness of a sintered sample.
