“…Porosity of corrosion-resistant steels has negative effect on corrosion resistance. This problem can be solved owing to use of the spark plasma sintering technology which allows to decrease porosity in sintered alloys to 1 % [9][10][11][12][13][14].…”

This work solves the problem of saving expensive chrome. This problem is proposed to be solved by grinding their waste of corrosion-resistant steels and reusing them. One of the most promising and industrially non-applicable methods for grinding any electrically conductive material is the electroerosion method. Comprehensive theoretical and experimental research is required to develop technologies for the reuse of electroerosive powders and evaluate the effectiveness of their use. The purpose of this work was to study the structure and properties of sintered samples from electroerosive corrosionresistant powders obtained in butyl alcohol. To perform the planned studies, Kh13 steel waste was selected as the dispersible material. Waste steel Kh13 was processed at a voltage on the electrodes of 100-110 V; the capacity of the discharge capacitors is 45 UF and the pulse repetition rate is 65-75 Hz. Butyl alcohol was used as the working fluid. The resulting powder was consolidated by spark plasma sintering (SPS) using the SPS 25-10 spark plasma sintering system. Based on the conducted experimental studies aimed at studying the structure and properties of sintered samples from electroerosive corrosion-resistant powders obtained in butyl alcohol, the high efficiency of the spark plasma sintering technology is shown, which provides a uniform heat distribution over the sample, controlled porosity and high physical and mechanical properties with a short working cycle time and grain growth suppression.
