“…When machining hollow shafts and rotors made of titanium alloys, it can be difficult to mill slotted and toothed parts due to their long length. However, there is also a general problem of machining such parts associated with the low wear resistance of metal-cutting tools [7][8][9][10][11][12][13].…”

The paper presents the results of theoretical and experimental research on tribotechnical characteristics: tool wear on the back surface, tool durability period, critical length of the cutting path before blunting, adhesion component of the friction coefficient, contact processes, temperature, and force dependences for the application of innovative nanostructured multilayer composite coatings on a tool for milling of titanium alloys. The proposed thermodynamic model of cutting tool wear allows us to determine the ways by which cutting tool wear intensity decreases and the conditions of increase in cutting tool wear resistance with wear-resistant coatings. A substantial increase in wear resistance of end mills when processing titanium alloys with the use of innovative multilayer nanostructured coatings is established, in particular an improvement of an average of 1.5–2 times. These positive results are related to a significant decrease in temperature–force loading in the cutting zone, a decrease in the friction coefficient (adhesion component), and the phenomenon of adaptation (self-organization) of friction surfaces during cutting by tools with wear-resistant coatings, contributing to the formation of films of various compounds with shielding, protective, and lubricating properties.

“…Increased requirements for safety and performance of structural elements operating in difficult conditions, lead to the necessity of their manufacture from the most perspective materials. Production of high-strength alloys is directly related to the various structural transformations that occur under certain temperature and speed modes [1][2][3][4]. Often the existence of desired structure is achieved by cooling of the material at a predetermined velocity [1].…”

The work deal with numerical modeling of the air cooling of cylindrical billet. The solution is carried out taking into account the dynamics of environmental air, radiation heat transfer, turbulence of the flow and conjugate heat transfer. The modeling process was realized in the accordance with a scheme of manufacturing of alloys with the structure of lower carbide-free bainite. A mathematical model has been developed by means of the finite-volume software Ansys CFX. The most effective mechanisms to control the cooling speed of the billet have been identified during numerical experiments.
