Analysis of friction and wear of ultrafine materials from the position of thermodynamics

Abstract

 Reasonable terms of loss of thermodynamic stability tribosystem and its adaptation to a decrease in wear rate on the movable frictional contact details of materials with ultrafine-grained (UFG) structure obtained by equalchannel angular pressing. Theoretically and experimentally established regularities of the influence of dispersion patterns and temperature frictional contact on the tribological characteristics of UFG materials.
