Abstract:

Soil processing is one of the most basic operations in vegetable production. This research project focuses on extending the service life of ploughshares by covering the tools with an oblique deposited overlaying material which is resistant to abrasive wear. The overlaying material was put in place parallel to the ploughshare’s head, both to the front part as well as the back. The new functional profile of the conventional tool was created with overlaying electrodes so that the processed soil could drop from the tool. Carbide type (Soudokay A43-0, OK Tubrodur 14.70, OK Tubrodur 15.82) and martensitic type (Filarc PZ 6159) materials were used. Tested variants (overlays OK Tubrodur 15.82 and Filarc PZ 6159 above all) proved that the service life of the area at the top of the ploughshare’s cutting edge was prolonged. This parameter is essential for effective ploughing.
