| Summary: | 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.
