“…Te formation of a fne-grained dissipative structure under friction provides increased wear resistance of tribocoupling elements since the coatings, flms, and nanoscale multilayer structure formed on the surface can show a shielding efect for mobile dislocations, which makes it difcult for them to go outside; as a result, the strength and creep limit, as well as the fatigue life of the subsurface layer, increase [31,32].…”

Self-organization mechanisms of metastable dissipative structures during friction depending on base and oil functional additives for hypoid gears are considered. Research was conducted on a software-hardware complex with simulation of gears’ operation in rolling with slipping conditions in start-stop mode. Indicators of formation of wear-resistant dissipative structures include the following: improvement of antifriction characteristics, lubricant boundary layers’ formation, contact surfaces’ strengthening, and formation of heterogeneous deformation microrelief with a fine-grained structure. The formation of chemically modified boundary layers on 90% of the contact area of tribo-coupling elements ensures an increase in the wear resistance of leading and lagging surfaces by 2 and 1.4 times, respectively. The sclerometry method was used to establish that the formation of dissipative structures when lubricating tribo-coupling elements with various transmission oils can reduce deformation processes in metal near-surface layers by 23%. Highly viscous flavored lubricant with distillate oil and additive composition ensures wear-resistant dissipative structures with active components, including oxygen, sulfur, and phosphorus.

In this work, the effect of annealing temperatures on the mechanical characteristics of (TiSi)N/CrN multilayer coatings obtained at a different working pressure of nitrogen and negative bias potential applied to the substrate was studied. The (TiSi)N/CrN multilayer coatings were obtained by vacuum-arc deposition using two electric arc evaporators with chromium and titanium-silicon cathodes under the regime of continuous substrate rotation. The element composition, phase state, and substructural parameters, and mechanical properties of the coatings under the influence of temperature were investigated. The X-ray analysis showed the presence of three phases in the coatings: cubic titanium nitride TiN and chromium CrN and tetragonal titanium nitride Ti2N. The microdeformation level of the initial coatings was high, 7.5 × 10-3. After annealing at temperatures of 400°C and 700°C, the phase composition of the coatings did not change. In contrast to the lower temperature annealing at 400°C, annealing at 700°C led to a decrease in the lattice parameters of all phases as compared to those in the initial state. These results indicate the thermal relaxation of stresses with the decrease of microdeformation level to 7.32 × 10-3.
