| 摘 要： | 提出了一种基于原子力显微镜的纳米材料弹性模量的测试方法，并应用原子力显微镜对薄膜涂层材料界面微观结构进行高倍观察，定量分析界面相的存在对界面弹性变形的影响.研究结果表明，实验样品为柔性界面；界面相具有晶界型纳米相的微观分布，该微观结构有助于缓解并阻止裂纹的产生，从而增强了纳米涂层材料的承载能力.从微观尺度上探索了界面相效应对材料弹性变形的影响.

| Abstract: | An elastic modulus test method of nano-materials was proposed based on atomic force microscopy(AFM).AFM was also used as a tool to observe the interface microstructure of a thin coating material and a quantitative analysis of the elastic deformation was made as a result of the presence of interface phase.The research results show that the sample here has flexible interface.The microstructure distribution of the interface phase is classified as grain-boundary nano-phase,and this kind of microstructure helps ... |
