Purpose - establishment of influence legitimacies of tribosystem dissipative properties on the wearproofness of conjugating surfaces. Research methods and apparatus - resonance bar, excited attenuation turning vibrations of the system, chromotographic. Theoretical and practical results. Set that the state of wearproofness is conditioned by the dissipative phenomena development of physical and chemical nature: the display of rheological properties (antivibration) by material both initial and such which are realized at its dynamic loading and by intensity and character of tribochemical processes. The physical and chemical model of friction and wear process is developed, which is based on viscidly resilient properties of solid. The receipt technology of the combined coverages is developed. The increase method of antiwear properties and termooxidizing firmness of oils is offered. Scientific novelty. On the basis of the complex approach to the phenomena, initiated by external friction, intercommunications mechano-chemical and rheological processes and their influence on tribotechnical descriptions of the united surfaces are set. It is discovered that in the friction conditions, unfavorable for flowing of mechanical relaxations, the increase of gas environment oxidizing activity initiates processes of topochemical relaxation which effectively warn the tribochemical reactions in the hard phase (fight). Efficiency of introduction. Causing of the combined coverages promotes the wearproofness of surface from 2 to 5 times. Application of anti-friction coverages allows to promote wearproofness of steel from 2 to 3 times and to reduce the force of friction from 6 to 12 times. The desorption from the commodity carbohydrate liquids of oxygen provides the increase of wearproofness of friction pair from 2.5 to 4.5 times, at enhanceable from 4 to 4.5 times and termooxidizing firmness of oils from 1.3 to 3.6 times. Sphere of the use: engineer, knots of friction constructing and improvement of machines, mechanisms, technological equipment.
