摘要:: 基于静态法和动态法分类总结了材料界面结合强度的常用评价方法，静态法主要包括剥离法、剪切法、拉伸法、弯曲法、纳米划痕法、激光划痕法、激光层裂法和无损评价法等；动态法主要包括单摆冲击划痕法、多冲接触疲劳法和滚动接触疲劳法等。此外，材料界面结合强度评价还可借助有限元辅助分析，该方法可模拟分析静态法、动态法等方法的测量过程。各种方法的优缺点及适用条件不同，因此应根据界面处两种材料的热学和力学性能等差异，选取合适的测量方法，再结合力学分析模型，选择合适的求解方法，得到材料的界面结合强度。随着新材料和新型表征技术的涌现，研究者们需要不断改进现有的测试方法，使材料界面结合强度评价方法更加简单易行、定量准确。

Abstract:: Based on the classification of the static method and the dynamic method, the common evaluation methods of material interface bonding strength are summarized. The static methods mainly include peel method, shear method, stretch method, bend method, nano scratch method, laser scratch method, laser spallation method and non-destructive evaluation method. The dynamic methods mainly include single pendulum impact scratch method, repeated impact contact method and rolling contact fatigue method. In addition, there is a finite element analysis method, which can simulate the process of the static method and the dynamic method. Each evaluation method has its advantage, disadvantage and applicable condition. According to the difference of thermal and mechanical properties of the two materials in interface, the appropriate measurement method should be selected, and then the appropriate measurement method should be combined with the mechanical analysis model to select the appropriate solution method to obtain the interface bonding strength of the material. In addition, with the emergence of new materials and new characterization techniques, it is necessary to continuously improve the existing testing methods, so that the evaluation methods for the material interface bonding strength are simple and accurate.
