The patterns of the change in antifriction properties of contact due to strength characteristics of boundary films of physical and chemisorbed nature were examined. The purpose of the study was to establish the influence of lubricating and rheological properties of the boundary films, formed on the surface layers of metal activated by friction, on the kinetics of change in the friction coefficient. The method of estimation of tribotechnical properties of contact under non-stationary conditions with cutting off the lubricant feed to the friction zone was used. Its essence is in determining the period of the setting of contact surfaces and registration of lubricating, antifriction and rheological indicators in this period.
An increase in antifriction properties of contact during pure rolling was established, owing to localization of tangential shear stresses in the liquid phase of a lubricant film; an increase in the friction coefficient is caused by an increase in tangential shear stresses of the boundary structured chemisorption films during transition to rolling with slippage.
The influence of slippage between the contact surfaces was analyzed, the increase in which from 3 % to 40 % leads to acceleration of the period of occurrence of the first signs of the setting, which is manifested by an increase in the adhesive component of the friction coefficient during desorption of boundary layers. During the setting of friction pairs, an abrupt periodic decrease in the friction coefficient was established and the manifestation of hydrodynamic effects in contact during melting of boundary layers was observed. The results of the studies may be used for designing the friction pairs of machines and mechanisms, which operate under non-stationary conditions (variable speeds, loads and temperature).References
