Thin film lubrication, where lubricant film is applied only to the sliding point, is expected to be lubrication technology for micro machines such as hard disk drives. However, the lubrication phenomenon has not been fully quantified due to the difficulty of measurement. In this study, we aimed at building a method that simultaneously measures the lateral and normal forces generated by lubricant and deformation of lubricant films and obtaining fundamental knowledge for construction of theory of the thin film lubrication. For measurements of lateral and normal forces, we developed optical-fiber-probe based and quartz-tuning-fork based methods, respectively. Moreover, two stage imaging ellipsometric microscopy was developed for visualization of the film deformation. These measurement method revealed important phenomena for construction of thin film lubrication theory, which are different from those in conventional lubrication.

薄膜润滑是一种仅在滑动点涂抹润滑膜的润滑技术，有望成为硬盘驱动器等微型机械的润滑技术。然而，由于测量的困难，润滑现象还没有完全量化。在这项研究中，我们的目的是建立一种同时测量润滑剂和润滑膜变形产生的侧向力和法向力的方法，为建立薄膜润滑理论提供基础知识。对于侧向力和法向力的测量，我们分别开发了基于光纤探头的方法和基于石英音叉的方法。此外，还发展了两阶段成像椭圆偏振显微镜来显示薄膜的变形。这些测量方法为薄膜润滑理论的构建揭示了不同于常规润滑的重要现象。
