For the study, researchers selected reinforcing material, along with effective strengthening methods for the knives. These knives were intended to replace similar imported parts from MWS (Germany) on combines produced by Rostselmash plant LLC. During the study, the causes of the dispersion of blanks, wear in real operating conditions were determined, methods for optimizing charge materials for obtaining hardening coatings were described, material science studies of coatings containing wear resistance modifiers (B4C, WC). As an import-substituting material for strengthening coatings, completely similar in properties to the German one, a mechanical mixture of powders from nickel-based alloys of the PG-CP2, 3, 4 type with grinding powders of normal electrocorundum grades 14A, 13A with a grain size of 40-160 microns can be used. Induction surfacing of hard alloys (charges), at high frequencies (40-100, 150-220 kHz), using transistor inverter generators with a power of 100 kW and above, was used as a modern method of hardening knives, and laser surfacing (for blanks made of 65G steel) or laser thermal hardening (for blanks made of steel 6HV2S). The data demonstrating the effectiveness of induction surfacing to reduce knife wear are presented.
