| Outline of Final Research Achievements |
It is well known that the surface texture (roughness and waviness) plays an important role in tribology (friction, wear and lubrication), wettability etc. Therefore, there are many researches on surface texturing. However, there are few theoretical background on optimum surface texture. In order to change this situation, we studied the modeling and simulation of three dimensional surface texture. We found that the mixture of short-wavelength component and long one (power index in auto-correlation function) depends on fabrication method on surface texture and affects contact conditions of surfaces.
