Electrokinetic Phenomena in Near Surface Layers of Metal Polymer Friction Elements
Abstract—
This article discusses the near surface layers of polymer lining of a spot-type disk brake and proposes the algorithm of nonequilibrium thermodynamics, which contains thermal conductivity and electrokinetic phenomena in near surface layers of polymer lining. The possibility of application of nonequilibrium dynamics with linear regimes in tribocouplings of friction devices has been substantiated and the electrokinetic effect has been revealed. It has been demonstrated that due to the cross effect with temperature gradients there exist two equilibrium states for metal friction elements: steady state surface temperature and thermal stabilization state. For the polymer lining the equilibrium state is understood as burnout of binding components from its near surface layer with formation of fluid islands. The relations of parameters have been formed equaling the Onsager and Saxen relations, which allows one to determine the parameters by calculations. The electrokinetic effect can be used for removal of moisture from the friction surface of brakes, thus providing stability of the friction coefficient.
期刊介绍:
Journal of Friction and Wear is intended to bring together researchers and practitioners working in tribology. It provides novel information on science, practice, and technology of lubrication, wear prevention, and friction control. Papers cover tribological problems of physics, chemistry, materials science, and mechanical engineering, discussing issues from a fundamental or technological point of view.
