Development of Deformation-Mechanism Based Parameters for Improved Design of Hard Coatings

在广泛的机械、生物医学和传感应用中，使用薄的硬质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理的详细了解，这些涂层的优化设计受到严重限制。拟议的项目将使用新的纳米压痕和电子显微镜技术，为基于机制的变形模型奠定基础。然后，这些模型将用于开发具有更长使用寿命的新涂层体系结构，以及预测涂层寿命和开发用于涂层评估的简单工具。

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.
