Abstract
The article discusses some ways to improve the wear resistance of technical coatings on the surfaces of cutting tools. These coatings were formed in two stages: diffusion saturation with nitrogen (nitriding) and the use of (Ti, Cr) N solid coatings through the process of applying a cathode arc discharge plasma. The proposed coating option also includes an additional ion doped layer implanted on the previously nitrated surface of high-speed steel. Such a multi-layer coating significantly increases (2.1–2.4 times) the wear resistance of the cutting tool due to the expansion of the stage of normal wear. The influence of 16 chemical elements and four antifriction materials implanted into the base surface on the wear resistance of a high-speed steel cutter with technical surface coating was investigated.
