利用扫描电子显微镜原位微压缩技术对多种氮化铬基硬质涂层的高温性能进行了评价。这允许首次直接测量这种涂层的高温抗压强度，而不是硬度。涂层的显微结构进行了分析，使用X射线衍射和聚焦离子束截面，然后用电子显微镜。在压缩之前、期间和之后使用电子显微镜检查微柱。讨论了变形行为和破坏应力随温度的变化趋势与涂层的微观结构和室温力学性能的关系。
The elevated temperature performance of a wide range of chromium nitride-based hard coatings was evaluated usingin situmicro-compression in the scanning electron microscope. This allows the first direct measurement of the high temperature compressive strength, rather than the hardness, of such coatings. The microstructure of the coatings was analyzed using X-ray diffraction and focused ion beam cross sectioning followed by electron microscopy. Micropillars were examined using electron microscopy before, during and after compression. Trends in deformation behavior and failure stress with temperature are discussed in relation to the coatings' microstructures and their room temperature mechanical properties.
