The lift generating mechanism of a diamond film and control by fine surface structure.

本研究通过抛光金刚石膜表面的平坦部分和表面细度的混合现象，定量地评价了摩擦减量条件与表面细度形状的关系，并表现出突出的滑动特性。我对接触和表面稳定状态的边界域进行了详细的验证，具体来说，适度抛光的多晶金刚石膜清楚地显示出超低摩擦干。结果表明，抛光金刚石膜作为一种滑动部件，在混合润滑低速滑动的流体润滑域高速滑动的所有域中都产生稳定的接触变化状态。此外，我能够解决这一现象的建模，并能够清楚地表明，流体润滑的变化是由平坦部分和未抛光部分的比例引起的。

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.
