“…Over a long period of time, surface hardening in order to increase wear resistance used a variety of techniques, which boiled down to the use of chemical-thermal treatment in an oxygen-rich environment. Among them are pulsed contact heating [4][5], technologies that combine the use of surfacing of abrasive-resistant coatings using adhesive-polymer abrasion-resistant dispersed composites [6][7], strengthening by electric contact welding [8] and a host of others. This leads to the enrichment of the final product with oxygen, hydrogen and other gases, both in quantity and in the form of chemical compounds that have a negative impact on the strength characteristics.…”

It is shown that tillage machines operate under conditions of abrasive wear, and their durability is largely determined by the operational life of the working tools. The main working tools of a plow include an earth board, cultivators – blades, harrows – teeth and discs, seeders – seed shoe. The working tools of tillage machines are mainly subject to abrasive wear. The blade of the soil cutting tools during operation loses its operability due to abrasive wear and therefore it must be reconditioned. There are various methods of reconditioning and hardening of working tools that increase their wear resistance and durability. The paper analyzes the methods of reconditioning and hardening of working tools of tillage machines. The study was based on information materials from Russian scientific and educational organizations and industrial companies, test reports of tillage machines conducted by machine testing stations, factographic and documentary databases of Rosinformagrotech. The generalization and analysis of information made it possible to establish that welding a blade-patch with subsequent welding of the wear-resistant material Castolin PE1229 allows increasing the life of an earth board during operation in southern chernozem soils by 4.6-5.0 times. The application of epoxy-sand composites increases the durability of earth boards by 2.2-2.7 times. Carbo-vibro-arc hardening of duckfoot teeth allows increasing the time between failures by 2.1 times compared to the serial one. Plasma spraying of powder materials increases wear resistance of duckfoot teeth by 1.5 times, and the application of pulse electric contact heating during hardening of earth boards reduces the intensity of their wear in loamy soils by more than 17%.
