Wear-resistant coatings based on niobium nitride

Abstract The results of studies of the use of niobium nitride and its modifications as a material of wear-resistant coatings are presented. It is shown that coatings based on niobium nitride have higher values of mechanical properties. The use of such coatings changes the thermal and stress state and increases the shape stability of the cutting wedge of the tool, which reduces the intensity of wear.
