Abstract

The possibility of estimating the defect sizes during the preparation of samples with artificial defects using eddy current testing is considered. The designs of orthogonal and absolute eddy current probes are compared, and it is recommended to use absolute eddy current probes for materials with a high electrical conductivity. An analysis of the obtained experimental results shows that the sensitivity and accuracy of the eddy current method can be significantly increased during static loading of samples (creation of tensile strains in the defect zone). This finding will allow us to prepare samples with defects the sizes of which are significantly smaller than those detected by standard control systems.

涡流检测在人工缺陷样品制备中的应用

摘要

考虑了在使用涡流检测制备具有人工缺陷的样品期间估计缺陷尺寸的可能性。比较了正交和绝对涡流探头的设计，对于高电导率的材料，推荐使用绝对涡流探头。对所获得的实验结果的分析表明，在样品静态加载（在缺陷区域中产生拉伸应变）期间，涡流法的灵敏度和准确性可以显着提高。这一发现将使我们能够制备缺陷样品，其尺寸明显小于标准控制系统检测到的缺陷尺寸。
