| Abstract | Friction is a representative phenomenon of tribology caused by sliding motion and rolling motion. The function and operational performance of mechanical components are remarkably infl uenced by friction. The role of boundary lubrication is dominant in the operation of tribo-mechanical components since severe operating conditions can be allowed due to the improvement of processing accuracy in the surface fi nishing of mechanical components. Therefore, the clarification of the generation mechanism of friction with a relative motion in which a viscous effect is not included is important in analyzing the performance of mechanical components. It is the real contact area that becomes a starting point when the generation mechanism of the boundary friction is discussed. Therefore, more detailed discussion of the concept of real contact area is required. In this paper, we introduce mainly the content discussed in our research group regarding this subject. |
