METHOD TO PRODUCE WEAR-RESISTANT WORKING SURFACE OF TILLAGE MACHINE PARTS OF STREAMLINE SHAPE Russian patent published in 2015 - IPC B23K9/04 A01B13/16 

FIELD: machine building.

SUBSTANCE: wear-resistant adding material is welded up along the working surface of a part with streamline shape, the said material is presented as identical strip sections 2-4 mm thick which are parallel to each other, arranged in staggered order at the right angle to the direction of the part's working surface movement. The length of the strip sections is 5-7 times more than their width, and the distance between them amounts to not more than the width of the welded up strip, and the distance between the adjacent strips is equal to the strip width. The longitudinal symmetry axis of the central welded up strip is placed in the same plane as the symmetry axis of the working surface is, in the movement direction of the latter.

EFFECT: invention allows for the decrease of wear rate of base metal in the zone of most intense friction of the part's working surface with streamline shape by means of increasing the degree of deformation and hoeing of the near-surface active soil layer in the movement direction.
