“…Te analysis of the tribotechnical indicators of the tribosystem when lubricated with plastic lubricants established the greatest infuence on steel wear of such parameters as contact load, specifc work of friction, and the thickness of the lubricating layer [25]. Te authors proposed an empirical dependence of the wear of tribo-coupling elements on the specifed factors, which allows predicting their intensity of wear in critical conditions, which include the conditions of the transition of the tribosystem to the semidry lubrication mode with a limited supply of lubricant to the friction zone.…”

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.
