Study of Tribotechnical Properties of Multilayer Nanostructured Coatings and Contact Processes during Milling of Titanium Alloys

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