The article investigates the theoretical foundations of steel saturation with carbon and nitrogen. The chemical composition, properties, microstructure, hardness, microhardness and depth of the surface coating of nitrocarburized steel samples and parts have been studied. The surface layers of cast parts of tillage machines with a coverage depth from 1.5 to 2.0 mm are analyzed. The results of abrasive wear of surface-coated cast specimens before and after heat treatment of quenching with subsequent tempering are presented. It has been proven that optimal heat treatment of parts increases the abrasive wear resistance and durability by 2-3 times.
