METHOD FOR HARDENING CUTTING PARTS OF CULTIVATOR SHARES Russian patent published in 2023 - IPC B23P6/00 C21D9/18 A01B35/20 

FIELD: metalworking.

SUBSTANCE: invention relates to methods of surface hardening of tools of agricultural machinery by electromechanical processing. The method includes surfacing of the cutting parts with a wear-resistant alloy and their electromechanical processing by creating a pressing force of the electrode-tool to the surface of the cutting part and a current density of up to 10⁹ A/m² with the formation of continuous hardening zones up to 3 mm deep and 3.5-7 mm wide parallel to each other. First, a wear-resistant alloy is deposited on the upper or lower surface of the cutting part of the cultivator share, and then its other surface is electromechanically hardened. The first zone of electromechanical hardening is formed parallel to the cutting edge and at a distance of 1-3 mm from it, and the subsequent zones are formed at a distance of 0.5-5 mm from each other.

EFFECT: increased durability of cultivator shares by increasing wear resistance to abrasive wear by increasing the area of hardened surfaces of their cutting parts.
