U.S.-Germany Cooperative Research: Ultrasonic Force and Friction Force Microscopy Applied to Thin Lubricant Films for Magnetic Storage Media

9815795 Bhushan该奖项支持来自俄亥俄州州立大学的Bharat Bhushan博士和两名研究生与德国萨尔布吕肯弗劳恩霍夫无损检测研究所（IZFP）应用科学系的Walter Arnold合作。 该奖项资助的研究将利用IZFP开发的动态力显微镜技术，也称为超声原子力显微镜（AFM），可用于测量比传统AFM大几个数量级的速度下的静摩擦。 陶瓷和聚合物复合材料的局部灵敏度测量可以达到其他技术无法达到的程度。 这项合作将使德国技术转移到俄亥俄州的计算机微摩擦学和污染实验室成为可能。 该研究计划将开发分析工具和计算机模型，以深入了解非均匀材料的弹性，这最终可能导致新的低摩擦材料和有用的机械性能测量技术。

9815795BhushanThis award supports Dr. Bharat Bhushan and two graduate students from Ohio State University in a collaboration with Walter Arnold of the Department of Applied Science at the Fraunhofer Institute for Nondestructive Testing (IZFP) in Saarbruecken, Germany. The research funded by this award will make use of the techniques in dynamic force microscopy developed at the IZFP, also called ultrasonic atomic force microscopy (AFM), which can be used to measure static friction at velocities several orders of magnitude larger than that used in conventional AFM. Localized sensitivity measurements of ceramics and polymer composites can be made to a degree not possible with other techniques. The collaboration will make it possible to transfer the German technology to the Computer Microtribology and Contamination Laboratory at Ohio State. The research plan will develop analytical tools and computer models to gain insight into the elasticity on nonhomogeneous materials, which could ultimately lead to new low-friction materials and useful mechanical property measurement techniques.
