Micromechanical characterization of the fracture behavior of nanostructured layers (A07*)

为了使氮化物和氮氧化物涂层更好地应用，本课题主要研究了两个方面的问题：通过微观力学测试，确定涂层的化学成分和微观结构与其力学性能之间的关系。在此基础上，将建立一个跨项目的力学模型，该模型将直接和跨尺度地耦合物理测量以及原子和连续介质机械方法，以加速未来的工艺和材料设计。

In order to tailor nitride and oxynitride coatings for application, this project focusses on two research topics: by means of micromechanical testing, the relationships between chemistry and microstructure of the coatings and their resulting mechanical properties will be determined. Based on this, a mechanical model will be established across projects which will couple directly and across scales the physical measurements and the atomistic and continuum mechanical approaches in order to accelerate future process and material design.
