Main problem described in this paper is that well-known theoretical approaches to calculate the actual contact area do not take into account the effect of time of loading and temperature of the contacting surfaces of solids. In modern tribology [1, 2] wide range of phenomena caused by interaction of the contacting surfaces of solids under normal load, offset, deformation of the material surface and the gas-liquid environment between the two contacting surfaces. Contact interaction in friction pairs largely determines their frictional characteristics, durability, and is therefore an important object of tribology. By term of contact is understood the interaction of solid surface under the influence of external forces considering their deviation from the ideal form, as well as participation in the deformation of the environment (gas and lubricants presence in the area of contact and indirect temperature). Main characteristics of the standard geometry of the rough surfaces are also examined in this paper.
