This research evaluated quantitatively the relationship of friction reduction conditions and surface fine shape by the flat part of the polishing diamond film surface, and mixture of fine asperity about the phenomenon which shows the outstanding sliding characteristic. I verified in detail about the boundary domain of the stable state of contact and surfacing, and, specifically, the poly-crystal diamond film which gave moderate polishing showed clearly that super-low friction dry is shown. As a result, it was shown that the polishing diamond film as a sliding component produces the stable contact change state in all the domains of high-speed sliding of a fluid lubrication domain from low-speed sliding of mixture method lubrication. Furthermore, I was able to tackle modeling of the phenomenon and was able to show clearly that fluid lubrication changes are induced by the ratio of a flat part and an unpolished part.

本研究通过抛光金刚石膜表面的平坦部分，以及表现出突出滑动特性的微细凹凸混合现象，定量评价了减摩条件与表面微细形状的关系。我详细验证了关于接触和堆焊的稳定状态的边界域，特别是，给出适度抛光的多晶金刚石膜清楚地显示出超低摩擦干燥。结果表明，作为滑动成分的抛光金刚石膜从混合方法润滑的低速滑动在流体润滑域的高速滑动的所有域中产生稳定的接触变化状态。此外，我能够处理这种现象的建模，并能够清楚地表明，流体润滑的变化是由平面部分和未抛光部分的比例引起的。
