Abstract

Eddy current testing (ECT) has been used for quite a while now and has been proven a reliable surface inspection technique for conductive materials. In the last 15 to 20 years, this technique has evolved toward the use of eddy current arrays (ECAs), and many applications can now benefit from this configuration to improve data quality, inspection speed, and ease of deployment, and considerably reduce operator dependency. The physics principle behind ECT and ECA is the same and was addressed in a previous issue of Materials Evaluation (Wassink et al. 2021). In this paper, we will discuss the main differences between ECT and ECA as well as how the arrangement of coils in an array can allow for optimized detection capabilities on different materials or types of defects. Common applications where ECA has demonstrated its strength will also be discussed.

了解涡流阵列用于高性能检测

涡流检测（ECT）已经使用了很长一段时间，并且已经被证明是一种可靠的导电材料表面检测技术。在过去的15到20年里，这项技术已经发展到使用涡流阵列（ECA），许多应用现在可以从这种配置中受益，以提高数据质量、检查速度和部署的简易性，并大大减少对操作员的依赖。ECT和ECA背后的物理原理是相同的，并在前一期《材料评估》中进行了阐述（Wassink等人，2021）。在本文中，我们将讨论ECT和ECA之间的主要区别，以及阵列中线圈的排列如何能够优化对不同材料或类型缺陷的检测能力。还将讨论ECA已证明其实力的常见应用。
