The friction and wear behavior of surfaces is significantly influenced by tribologically induced modification of the boundary surface and structure and depends on environmental conditions to a great extent. Coating of a surface allows targeted modification of these tribological properties, particularly with regard to global challenges like energy efficiency and conservation of resources. The emphasis of this proposal is to access the essential physical and chemical processes in dry running fric-tion contacts, which will be analyzed using homogeneous coatings of tetra-hedral amorphous carbon (ta-C) and Molybdenum(IV)-disulfides (MoS2). Both materials represent scientifically and technically relevant coating systems that undergo a characteristic change in structure and exhibit com-plementary properties concerning friction, wear and the influence of the atmosphere. A heterogeneous, structured coating system of both materials opens the potential to combine very low fric-tion (MoS2) and highest wear resistance (ta-C) and will be investigated here for the first time. In systematic experiments the influence of coating properties, counter body material, vacuum, and atmospheric gases will be studied for homo-geneous and heterogeneous coating systems. The experimental and analytical foundation of this project is based on a new, worldwide unique experimental setup that combines a universal vacuum tribometer with a cluster tool. The cluster tool comprises Rutherford backscattering (RBS), elastic recoil detection (ERD), spectroscopic ellipsometry of reflectometry, and Raman spectroscopy. Thereby, it provides the necessary in-line instrumentation for element specific depth profiling, coating thickness, and optical and structural analysis, allowing the characterization of tribologically induced processes without breaking vacuum or exposure to ambient air. In an unprecedented way, this proposal links tribological characterization of new coating systems in defined atmospheres with complex in-line analysis. Setup and qualification of the vacuum tribometer have been carried out as a part of a Major Research Instrumentation Program and based on a long lasting cooperation of the Institute of Manufacturing Technology at Technische Universität Dresden (TUD) and the Ion Beam Center at Helmholtz-Zentrum Dresden-Rossendorf (HZDR).

表面的摩擦和磨损行为受到摩擦学诱导的边界表面和结构的修饰的显着影响，并且在很大程度上取决于环境条件。表面涂层允许针对这些摩擦学特性进行有针对性的修改，尤其是在能源效率和资源保护等全球挑战方面。该提案的重点是访问干摩擦接触中的基本物理和化学过程，将使用二甲状腺异形碳（TA-C）和钼（IV） - 硫化物（MOS2）的均匀涂层（MOS2）对其进行分析。两种材料都代表了科学和技术相关的涂料系统，这些涂料系统在结构和裸露的摩擦，磨损和大气影响方面经历了特征变化。两种材料的异质，结构化涂料系统都开放了将非常低的Frich-tion（MOS2）和最高耐磨性（TA-C）相结合的潜力，并将首次在此进行研究。在系统的实验中，将研究涂料性能，反体材料，真空和大气气体的影响，以实现同性涂层和异质涂层系统。该项目的实验和分析基础是基于新的，全球独特的实验设置，该设置将通用真空摩擦仪与群集工具结合在一起。簇工具包括卢瑟福反向散射（RB），弹性后坐力检测（ERD），反射仪的光谱椭圆形和拉曼光谱法。因此，它为元素特定的深度分析，涂层厚度以及光学和结构分析提供了必要的内线仪器，从而可以表征摩擦学诱导的过程，而不会破坏真空或暴露于环境空气。该提案以前所未有的方式将新涂料系统的摩擦学特征与复杂的在线分析联系起来。真空摩擦仪的设置和资格是作为主要研究仪器计划的一部分进行的，并基于TechnischeUniversitätDresden（TUD）和Helmholtz-Zentrum Dresden-Dresden-Dresden-Rossendorf（HZDR）的INSISCHEUniversität（TUD）的持久合作。
