摘要
物体内部缺陷是指表面以下的裂纹、杂质、疲劳损伤以及腐蚀,此类缺陷因具有隐蔽性而严重影响产品质量和运行安全。以光学元件和飞机叶片为例,分析内部缺陷形成机理和形貌特征。将内部缺陷无损检测分为有激励无损检测和无激励无损检测,并着重介绍了热激励和磁激励无损检测的原理和研究成果。
Abstract
Inner defects of object are cracks, impurity, fatigue damage and corrosion under surface. The defects are secluded so that they deteriorate the quality of product and safety of operation seriously. Taking optical components and aircraft blades as examples, we analyze the forming mechanism and the characteristic of inner defects. Non-destructive detection of inner defects is categorized into energizing and unenergizing non-destructive detection. This paper focuses introducing the principles and research achievements of thermal excitation non-destructive detection and magnetic pumping non-destructive detection.
