USE OF NON-EQUILIBRIUM THERMODYNAMICS AND THEORY OF SELF-ORGANIZATION FOR TRIBOSYSTEMS DESCRIPTION AND WEAR-RESISTANT MATERIALS DEVELOPMENT

Abstract

In the paper there is presented a practical use of the non-equilibrium thermodynamics and theory of self-organization in tribology with obtaining certain results particularly at the development of new wear-resistant materials. Wear intensity decreases with the decrease of manufacturing entropy. There are shown the results of the applied investigations of non-equilibrium thermody-namics and the theory of self-organization conformably to friction. Possible states of a body of friction with equal power imparted to a body from the point of view of en-tropy are considered. There are shown practical examples of wear intensity decrease by the example of sliding electrical contacts and antifriction alloys for sliding bearings. The results of the development of antifriction aluminum alloys made simultaneously on the basis of seven-nine alloying elements are considered. Besides, in experimental alloys there were added silicon, magnesium, zinc, titanium, that allowed decreasing wear intensity by about two times and decreasing tin content in an alloy by 1.5 – 2 times.
