Hardening of working bodies of agricultural machines by electric spark alloying

The article considers a way to increase the resource (durability) of the working bodies of agricultural machines. Working bodies worn to the limit size are subject to restoration, and those that have not reached the limit size are sharpened to the nearest repair size. The disadvantage of this technology is that it allows too large a range between adjacent repair sizes, and this leads to a significant reduction in the resource of working bodies. The authors propose a way to increase the resource of working bodies, taking into account the tolerance for sharpening.
