METHOD OF PRODUCTION OF WEAR-RESISTANT WORKING SURFACE OF PARTS OF TILLERS Russian patent published in 2015 - IPC B23P6/00 B23K9/04 A01B15/04 

FIELD: agriculture.

SUBSTANCE: invention can be used for application of wear-resistant coatings on working surface of parts of tillers, having a shape of oblique wedge using fusion welding. The wear-resistant filler material is applied to the said surface in the form of parallel strips with a thickness of the weld layer of 2-4 mm at a right angle to the direction of displacement of the working surface of the part at a distance from each other of not more than 15 times the layer thickness. The strips are applied to the upper and lower inclined faces in the area of compressing stress of the working surface of the part with a shift from each other by the same distance in the direction of movement of the parts. The width of the weld strips on the work surface of the parts is set not more the double thickness of the weld layer.

EFFECT: invention enables to reduce the wear rate of the working surface of the parts by deformation and reduction of the density of the surface active layer of the soil in the area of the greatest intensity of friction.
