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.
