Friction is a technologically extremely important phenomenon. The search for possibilities to influence and control it is a challenge. Friction depends on the surface structure and on adsorbates. This project aims at a better understanding of such possible influences on friction and their origin. Friction force measurements shall be performed by means of an atomic force microscope (AFM) at electrode surfaces. The advantage in electrochemical friction force measurements is that adsorbate layers (both metallic and organic) can quickly be formed and removed by changing the potential. On the other hand, in future this understanding of friction might help in obtaining a better understanding of the structure at the metal /electrolyte interface and its dynamics.The transition to wear shall also be examined as well as its role in nanostructuring procedures by AFM and STM.

摩擦是一种极其重要的技术现象。寻求影响和控制它的可能性是一项挑战。摩擦力取决于表面结构和吸附物。该项目旨在更好地了解这些可能对摩擦的影响及其起源。应通过原子力显微镜（AFM）在电极表面进行摩擦力测量。电化学摩擦力测量的优点是，吸附层（金属和有机）可以快速形成，并通过改变电位去除。另一方面，在未来，这种摩擦的理解可能有助于更好地了解在金属/电解质界面的结构和它的dynamics.The过渡到磨损也将被检查，以及其在纳米结构化过程中的作用，通过AFM和STM。
