The use of thin hard abrasion-resistant coatings is an important method for significantly improving the operational lifetime of components in a wide range of mechanical, biomedical and sensory applications. The optimal design of these coatings is however severely restricted by a lack of detailed knowledge of their material deformation mechanisms. The proposed project will use novel nano-indentation and electron microscope techniques to create a basis for mechanism-based deformation models. These models will then be used to develop new coating architectures with improved operational lifetimes as well as predicting coating lifetimes and developing simple tools for coating assessment.

在广泛的机械、生物医学和感官应用中，使用薄而硬的耐磨涂层是显著提高部件使用寿命的重要方法。然而，由于缺乏对其材料变形机制的详细了解，这些涂层的优化设计受到严重限制。该项目将使用新型纳米压痕和电子显微镜技术，为基于力学的变形模型奠定基础。然后，这些模型将用于开发具有改进使用寿命的新涂层架构，以及预测涂层寿命和开发用于涂层评估的简单工具。
