METHOD FOR HARDENING CUTTING PARTS OF CULTIVATOR SHARES BY SPOT ELECTROMECHANICAL TREATMENT Russian patent published in 2021 - IPC C21D9/18 

FIELD: cutting tools.

SUBSTANCE: invention relates to a method for hardening the cutting parts of a cultivator share by spot electromechanical treatment. The method includes electromechanical treatment of the surface of the cutting parts of the cultivator share by creating a pressing force and a current density of up to 10⁹A/m2, forming hardening areas at a depth of 3 mm. Treatment is conducted along the cutting part of the share in sections with a diameter of 6 to 8 mm in two rows, wherein the centres of the sections in the rows are located on the same line from the edge of the cutting parts of the cultivator share at a distance of 3 to 4 mm for the first row, at a distance of 8 to 10 mm for the second row, and at a distance of 10 to 14 mm between the adjacent sections in the rows.

EFFECT: increased durability of cultivator shares due to the increase in the strength, hardness and wear resistance to abrasive wear of the cutting blades with the provided effects of self-sharpening and formation of a sawtooth blade during the operation of the products.
