摘要
失效分析是故障分析的重要方法,而扫描电镜为失效分析的重要手段,两者在工程领域有着广泛的应用,尤其是在断口分析中的应用。通过扫描电镜可以确定失效的形式和机理,对于确定故障的原因和制定措施起着关键作用。笔者通过工程具体的实例,结合失效分析理论,应用扫描电镜的分析,针对具体工程问题分析了原因,并制定了措施,着重介绍了扫描电镜在失效分析中的应用。
Failure analysis is important method for identification of engineering failure.And scanning electron microscope（SEM） is instrument of failure analysis.Both two are effecting widely across engineering field especially application of fracture analysis.Failure mode and root cause can be identified;meanwhile countermeasure can be made through SEM.This article will explain application of failure analysis by SEM through an actual engineering failure case.In this case,root cause is identified and countermeasure is made through aid of SEM.
