Research Abstract

It was reported that in the case where partially-polished diamond-coated surface is used for sliding, the friction coefficient is drastically reduced as sliding speed increases. It was also reported that the surface texturing results in good tribological performance of sliding surfaces. The reason of their good tribological performance may be because the lift force is induced by the surface structure in micro/nanosclale gas flow between sliding surfaces. However, the understanding of these phenomena is not enough, and, the past researches were performed by the trial-and-error method. In the present work, in order to understand these phenomena clearly, the mechanism of high gas pressure generation induced by the micro surface structure was theoretically clarified. Using the knowledge obtained here, we clarified the optimal shape of surface structure. Our theory was validated by the sliding experiment.
