It is well-known that process of friction depends immensely on the surface roughness. Also, surfaces change while in friction. Roughness change is influenced by many factors such as shape of asperities, physical characteristics of materials, load, sliding velocity, lubricant and others. It was shown experimentally that roughness reaches a steady form (known as ``equilibrium roughness'') while running-in process. It is ``equilibrium roughness'' that determines a stationary friction mode.
