It was established that the technology of electrospark alloying is a promising method of strengthening and restoration of parts and such technological and power equipment as shafts of pumps and electric motors, impellers, pump housings, centrifuges, etc. To increase the efficiency of the proposed technology, a number of electrode materials like FeNiSi – Cr3C5, WC – TiC – Mo2C – Co – Cr and WC – TiC – Co – Cr – Ni – Al, TiC– (Fe – Cr – Si – Al), NiCrBCuC – WC, FeNiCrBSiC – TiB2 and FeNiCrBSiC – CrB2 were created, which were tested at industrial enterprises of Ukraine. It was revealed that application of the developed electrodes provides a simultaneous increase in the manufacturability of the process of electrospark alloying with an increase in the life of parts of technological equipment by 2.0…2.5 times. 10 Ref., 4 Fig.
