“…The studies have shown that with the low Al content in the Ti 1−x Al x N coating, a solid solution (substitutional solution) of Al forms in the crystalline lattice of TiN, with the cubic structure. At 0 ≤ x ≤ 0.40, the films with the NaCl structure were synthesized, while the interplanar distance d 002 , measured from the X-ray spectra, decreased linearly with an increase of AlN in the film [58]. A significant factor is the irregular distribution of the Al concentration over the volume of the film material [59].…”

This article discusses the influence of the thickness of a nano-structured wear-resistant layer of the Ti–TiN–(Ti,Al,Si)N multilayer composite coating on its mechanical and performance properties. The study was focused on the coatings with the following thicknesses of its wear-resistant layers: 2, 3.5, 5, 7, 11, and 15 μm. The relation between the thickness of a wear-resistant layer and the time of its deposition was investigated, and the effect of the above thickness on hardness and wear resistance in scratch testing was considered. Cutting tests were conducted in turning steel C45 with carbide inserts with the coatings under study at various cutting speeds (vc = 250, 300 and 350 m/min). The study found the value of thickness of wear-resistant layer providing the longest tool life at various cutting speeds. The differences in the nature of wear for the coatings with various thicknesses of wear-resistant layers were considered.

“…As it was determined in the first and some other studies a complex surface structure is formed by diffusion processes when ion nitriding of steel M2 in the gas plasma of the vacuum arc discharge in a pure nitrogen atmosphere [2,3,4,16]. This structure consists of a continuous nitride layer and underlying diffusion layer which is a solid solution of nitrogen in martensite, Fig.…”

The article deals with the influence of the vacuum plasma surface treatment on the life of the face milling cutter of high-speed steel R6M5 (analog M2 (USA, AISI/ ASTM)). Such processing combines ion nitriding in gas plasma and the deposition of the wear-resistant TiAlN layer in the metal gas plasma of the vacuum-arc discharge. Research verifies that the use of vacuum plasma treatment combining the formation of the transition nitrided layer in the gas plasma and the subsequent deposition of TiAlN coating in metal gas plasma created by a vacuum-arc discharge is an effective way to improve the tool life of high-speed steel face milling cutters.

“…Nitrides possess high hardness and are widely used as coatings for the increase in the service life of the cutting tool [1][2][3][4][5]. On the other hand, there are few published works that are devoted to the study of the friction characteristics of nitride-based coatings with the thickness of the applied layer of 2-6 μm.…”

The tribotechnical characteristics of nitride coatings in a pair with a diamond on air have been determined. The friction has been applied in the range of velocities of 6-16 mm/s and loads on diamond in the range of 1.5-5.5 N. A decrease in the friction for all nitride coatings under study with a decrease in the slip velocity has been determined. The intensity of periodic wear of nitride coatings decreases with growth in the load and varies from 1.6 × 10 -6 to 5.3 × 10 -6 . High-entropy nitride coating possesses higher tribotechnical characteristics relative to mononitride coatings.
