Regularities in the formation of wear-resistant coatings on steel samples when machining them with electrical discharge

This paper considers the technology of electrical discharge machining of steel friction pairs and reports the results of experimental studies. Analysis of the experimental studies has shown that increasing the "anode-cathode" voltage leads to a sharp decrease in the micro-hardness of the s...
