FIELD: process engineering.
SUBSTANCE: invention may be used for making tillage machinery parts in conditions of abrasive wear, particularly, plough share. 4-5 mm-deep - and 6 mm-wide grooves are cut on plough share working surface in the area of expected wear, perpendicular, to plough share tip edge, distance between said grooves making 20-30 mm. Hard wear proof layer is deposited on plough share tip.
EFFECT: higher wear resistance.
