Nanoindentation enables the determination of microscopic material properties via miniaturized indentation tests. Coupled with lateral specimen movements, it is thus also possible to detect properties such as hardness, Young's modulus, coefficients of friction, fatigue behavior, wear resistance, etc. for individual phases of a material; in contrast to classical test methods such as tensile testing, hardness testing, etc., which can only provide information about the macroscopic material properties. A link between atomistic material structure and resulting macroscopic material properties as a function of the interfacial properties between individual phases can thus be established. This coupling and its understanding is of particular importance for the development, characterization, processing as well as the prediction of the operational behavior of multi-material systems. As the focus of research at the Clausthal Center of Materials Technology (CZM), such multi-material systems are naturally composed of a wide variety of, sometimes incompatible, phases or layers of different materials. Conversely, nanoindentation is an ideal tool for the targeted development of new multi-material systems with specific property profiles. In addition, nanoindentation provides important new insights into the precise phenomenological interactions in the generation and use of multi-material systems. The material groups of metals, non-metallic materials and polymers will be addressed via conventional and additive manufacturing routes. Due to the envisaged temperature support up to 600°C, the nanoindenter technology covers new extensive application areas for multi-material systems, but also measurement applications with regard to many thermal processes in manufacturing processes themselves are feasible. Furthermore, the interdisciplinary research approach pursued at CZM represents a unique characteristic. Working groups from the engineering and natural sciences will work in partly interdisciplinary projects with the large-scale research facility applied for. In particular, new findings in the field of nanoindentation itself can be expected through the connection with other highly sensitive analysis and preparation techniques such as scanning-electron-microscopy, scanning-transmission-electron-microscopy, electron-backscatter-diffraction, nano-Computer-tomography, atomic-force-microscopy, X-ray-photoelectron-spectroscopy, atomic-emission-spectrophotometry, physical-vapour-deposition, focused-ion-beam-analytics, etc., which are within the reach of the CZM surface analysis and functionalization working group.

纳米引导可以通过微型化的压痕测试来确定微观材料的性能。因此，与横向样本运动相结合，也可以检测诸如硬度，杨氏模量，摩擦系数，疲劳行为，耐磨性等的特性，以适用于材料的各个阶段；与经典测试方法（例如拉伸测试，硬度测试等）相反，该方法只能提供有关宏观材料特性的信息。因此，可以建立原子质材料结构与所得的宏观材料特性之间的联系与各个相之间的界面特性的函数。这种耦合及其理解对于发展，表征，处理以及多物质系统操作行为的预测特别重要。作为克劳斯特材料技术中心（CZM）研究的重点，这种多物质系统自然由各种不同材料的各种，有时不兼容的阶段或层组成。相反，纳米构件是具有特定属性配置文件的新的多物质系统的目标开发的理想工具。此外，纳米引导提供了对多材料系统的生成和使用中确切的现象学相互作用的重要新见解。金属，非​​金属材料和聚合物的材料组将通过常规和添加剂制造路线来解决。由于预期的温度支撑高达600°C，纳米内特技术涵盖了多物质系统的新广泛应用领域，但也针对制造工艺中许多热过程本身的测量应用本身都是可行的。此外，在CZM上采用的跨学科研究方法代表了一个独特的特征。来自工程和自然科学的工作组将与大规模研究机构一起在部分跨学科项目中工作。特别是，通过与其他高度敏感的分析和制备技术（例如扫描 - 电子 - 微观显微镜，扫描 - 转录 - 电子 - 微镜拷贝，电子 - 刻度 - 扫描式 - 及纳米 - 计算机 - 计算机，X摄影，Atomic-Forrosce-Microscopopy，X-MICROSCOPY，X-MICROSCOPY，XCROPPHY，x-MICROSPOPY，x-MICROSPOPY，XCROPY，原子发射 - 光谱测定法，物理蒸气沉积，聚焦 - 离子束 - 分析学等，它们在CZM表面分析和功能化工作组的范围内。
