Internal Defect Detection of Multilayer Dissimilar Metal Based on Pulse Eddy Current
摘 要
多层异种金属材料被广泛地应用于航空航天、国防、核工业等领域。由于异种金属材料的特殊性、复杂性,其内部容易出现缺陷,这对传统的无损检测技术提出了挑战。为了提高对该结构内部缺陷的检测能力,提出了磁集中脉冲涡流检测技术。通过设计优化涡流探头的结构参数和设计磁屏蔽方法聚集磁场,提高了内部缺陷的检测灵敏度。最后,使用磁集中结构的脉冲涡流探头对不同缺陷大小的多层异种结构试件进行了检测和方法验证,试验结果表明,设计的脉冲涡流检测平台能成功检测多层异种试件中的缺陷。
Abstract
Multi-Layer metal materials are widely used in aerospace, defense industry, nuclear industry and other important fields. There are defects in the interior part of the structures. Because of the particularity and complexity of this material, it is a challenge task for traditional nondestructive testing methods to detect these defects. This paper proposes a magnetic concentrated pulse eddy current detection technology to improve the detection capability of the internal defects. The detection sensitivity of the internal defects is improved through the optimization of the structural parameters of the eddy current probe and the design of the magnetic shielding shell. Finally, experimental tests of defects with different sizes in the multi-layer structures are conducted to verify this study.
