| 简要总结了层状复合材料界面结合强度的非传统评价方法。非传统界面结合强度评价方法包括:波振法(激光层裂法、应力波法、超声波法、电磁波法)、划痕法(激光划痕法)、辅助分析法(X射线衍射法、有限元法、解析法)和其他方法(电阻法)。波振法是将载荷以冲击波的形式施加在界面位置处,实现复层和基体分离。划痕法是将高能激光作用于复层,分离界面,实现界面结合强度的测量。电阻法通过建立界面电阻和界面强度之间的关系,评价界面结合强度。与传统界面评价方法对比,非传统评价方法有特殊优点:对材料的破坏程度小,有效抑制材料的弹塑性变形,测得界面强度接近界面本征强度。但非传统法也仍存在一些亟待解决的问题,随着新材料的不断出现,需要不断改进现有测试方法,使界面结合强度评价方法向着简单易行、无损、自动化的方向发展。 |

| This paper briefly summarizes unconventional evaluation methods for the interface bonding strength of layered materials. Unconventional evaluation methods for interface bonding strength of layered material include wave vibration methods (laser spallation method, stress wave method, ultrasonic method, electromagnetic wave method), scratching methods (laser scratch me-thod), auxiliary analysis methods (X-ray diffraction method, finite element method, analytic method) and other methods (resistance method). In wave vibration method, the load is applied on the interface in form of shock wave so that cladding layer and substrate are separated. In scratch method, high energy laser is applied to the cladding layer which cause the interface separation. Then the interface bonding strength of the material can be measured. In resistance method, the interface bonding strength can be measured by building the correlative relation between the resistance and interface bonding strength. By means of measuring interface resistance, the interface bonding strength is obtained. Compared with the conventional interface bonding strength evaluation methods, unconventional evaluation methods have special advantages. The damage degree to material is not serious, the elastic-plastic deformation is restrained effectively, the result of measured interface bonding strength is very close to the interface bonding intrinsic strength. Ho-wever, there are still some problems to be solved. It is necessary to continuously improve the existing testing methods, so as to make the evaluation methods of interface bonding strength simple and easy to operate, nondestructive and automated. |
