摘要: 针对利用扫描电子显微镜观察失效断口无法掌握宏观立体位置的问题,借助超景深数码显微镜和3D打印等多种3D技术提出解决方案。首先利用3D技术对断口进行成像,建立断口的3D立体形貌;然后利用计算机辅助技术建立断口的三维实体模型;最后借助该模型辅助扫描电子显微镜的断口显微观察。结果表明,3D技术可以很好地应用于金属结构件失效分析领域。

Abstract: In view of the problem that it is impossible to grasp the macroscopic stereoscopic position when observing the failure fracture with scanning electron microscopy (SEM), the solutions were put forward by means of multiple three-dimensional (3D) techniques such as 3D microscope with super wide depth of field and 3D printing. Firstly, the fracture surface was imaged by 3D technology, and the 3D stereoscopic morphology of fracture surface was established. Then, the 3D model of the fracture surface was obtained by computer-aided technology. Finally, the model was used to assist scanning electron microscopy conduct the micro examination of the fracture surface. The results indicate that 3D technologies can be well applied in the field of failure analysis of metal parts.

Key words: 3D techniques, failure analysis, fracture surface, microscopic observation, metal parts
