The influence of the preparation and use of various types of wear-resistant coatings on the tool shaver of high-speed steel R6M5K5 with a hardness of 60-65HRc for shavinging parts such as gear driven made of steel 20HGNMTA with a hardness of 160-210 HB. The use of hydroabrasive cleaning with ceramic balls made it possible to obtain a clean surface with a rounding of the cutting edge to 7 microns. For the analysis of durability, coatings based on titanium nitride (TiN) and a multi-component coating of titanium and aluminum (AlTiN) were used. The coating on the basis of titanium nitride (TiN) increased the resistance 1.35 times. Multi-component coating of titanium and aluminum (AlTiN) increased resistance 1.61 (AlTiN) times.
