Abstract

The paper proposes a technology of electroslag surfacing (ESR) with the use of modifying additives to increase the wear resistance of working bodies of agricultural machinery. Comprehensive theoretical and experimental studies have been carried out, and the optimal surfacing parameters have been determined. It has been established that the use of the developed flux-cored wires based on carbides and oxides ensures the formation of a fine-grained coating structure with a hardness of 48-50 HRC, which provides wear resistance of parts by 30-40%. Practical tests have confirmed an increase in the service life of parts by 35-40% and a reduction in repair costs by 25%. The proposed technology can be used in various industries.
