ABSTRACT
Boundary lubrication practically occurs in any lubricated friction units of machines and mechanisms. This mode of friction can be realized either in particular operating periods (such as start-stop, dead points in reciprocal motion, etc.) or permanently (at low speeds and high pressures and temperatures, and when contact geometry rules out of hydrodynamic lubrication). According to Gee and Rowe, “boundary lubrication is a condition of lubrication in which the friction and wear between two surfaces in relative motion are determined by the properties of the surfaces and by the properties of the lubricant rather than bulk viscosity” [1].
