deformation, tribomechanical, antifriction and wearproof properties of lubricant layers in contact
tribotechnical connections is developed. The contact-deformation mechanism for reducing the wear process
of the lubricant surfaces is established. The techniques of construction of deformation diagrams of the
lubricant surfaces and layers in normal and tangential directions are developed. The methods of determining
the factor of friction and dynamic viscosity on the basis of tests of samples under the pendular scheme and
equations of the state of tribosystem for the specified scheme of researches are offered. The analytical and
experimental investigations of characteristics of friction at moving the lubricant samples on direct and
inclined planes are conducted. The parameters which enable to estimate the modes of friction and lubrication
under different conditions are determined. The system of definition of functions of wear process intensity of
friction sites with a choice of optimum schemes of tests, conditions of lubrication and algorithm of
calculation of wear parameters for forecasting and optimization of durability by criterion of wear is offered.
