Oilynit (oleaginous polymer) is a multifunctional, universal wear inhibitor of tribosystems. It is an oil-filled polymer characterized by intellect: the ability of dynamically adjustment of its own functional properties at friction. The paper contains the comparative studies of physical, mechanical and tribological characteristics of two types of antifriction self-lubricating polymer composite materials, developed in Rostov State Transport University under the Maslyanit trade mark. The study of physical and mechanical properties of composites (microhardness, modulus of elasticity, elastic recovery) was carried out by the nanoindentation method on NanoTest 600, a special set-up for determining physical and mechanical properties of the materials. Tribological tests were carried out at a fixed sliding speed and a stepped loading on the friction machine of Amsler type by a “finger-roller” scheme. |
