The paper is devoted to one of the most important problems of increasing wear resistance of tribosystems due to the application of low-melting metal and porous coatings on tribocontact surfaces. The asymptotic and self-similar solution for zero and first approximation was found based on the true viscous fluid flow equation for the “thin layer”, equations of continuity, an equation describing the flow of a lubricant in the body of a porous surface coating of a bearing ring; and an equation describing the profile of the molten surface contour of a bearing ring coated with a low-melting metal alloy, i.e. as a result, excluding the metal coating melt and considering the melt the velocity and pressure fields in the lubricating and porous layers are determined; as well as the load capacity and the friction coefficient, which allows determining the increase of wear resistance – increase of hydrodynamic pattern due to porous and low-melting metal coating of contact surfaces of the tribosystem.
