Algorithm for Tribokinetic Modeling Tests of Triboconjuction Materials for Industrial Products

Abstract

An experimental-calculation procedure for determining the kinetic and energy activation criteria for assessing the wear resistance and compatibility of triboconjunction materials using the kinetic three-stage triboreaction is presented. The developed method for tribo-kinetic tests to determine the kinetic characteristics (order and rate constants) and activation energies for all three stages of the triboreaction was tried experimentally for steels ShKh-15 and 45, aviation fuel RT, aviation hydraulic oil AOH-10 and aviation oil MK-8 added with oleic acid. The conducted tribo-kinetic tests established kinetic and activation energy criteria for assessing the wear resistance of ShKh-15 steel and antiwear properties of RT and AOH-10 lubricants, as well as kinetic criteria for assessing the wear resistance of steel 45 and antiwear properties of MK-8 with oleic acid. Also, using the developed method for tribokinetic tests, the kinetic and activation energies of ShKh-15 in long-term storage aviation fuels "TS-1" and "TS-1*", kinetic criteria and activation energy for the second stage of the triboreaction, chemical modification ShKh-15 in the medium of "TS-1", as well as the established kinetic and activation energy of the triboreaction, that is, surface destruction, in fact, wear of steel 45 during reciprocating motion.

Methodological Approach in the Simulation of the Robustness Boundaries of Tribosystems under the Conditions of Boundary Lubrication

“…where RS TS(max) is the maximum value of the rheological properties of the combined materials in the tribosystem after running-in, measured in dimension m −1 , and is calculated according to the equations given in [42]. Formulas (7) and ( 8) are obtained for the specific design of the friction unit. The design is taken into account by using the shape factor, K f .…”

“…For example, in [4], a mathematical model for predicting the reliability of rolling bearings is developed on the basis of the hierarchical Bayesian method of maximum entropy. Theoretical developments that show the relationship of wear with the thermodynamic concept of entropy are presented in [5][6][7]. This approach allowed the authors of the work to study the effect of consistent grease on the resources of tribosystems.…”
