This research deals with the influence of the surface roughness on the friction properties. This paper is examined on the effects of various factors on the relationship between the indented depth and the friction coefficient. The friction mechanism between the hard hemispherical projection of the radius of curvature r modeled on the asperity of a hard material surface and the soft surface has been theoretically analyzed taking into consideration with the frictional resistance caused by the ploughing and shearing term. The results of numerical examples based on theoretical analysis can be expressed as follows. The friction coefficient for the smooth soft surface is increased with the increase of a contact angle that obtains from the radius of curvature and an indented depth of the hemispherical projection. Friction coefficient for a soft surface with the asperities periodically fluctuates with the increase of an indented depth and the friction coefficient between the hard projection and the smooth soft surface has a converging tendency.
