The Research on Steel Plate Defects Inspection by Magneto-acoustic Testing with Induction [PDF]
, 2015 随着工业化的发展，钢材被应用在了各种各样的领域，比如：天然气管道、轮船、汽车等等。然而，随着时间的推移，钢材在使用过程中会出现腐蚀、裂纹等缺陷，这些缺陷严重影响了使用的安全，所以必须在事故发生之前对其进行检测以评估其安全性。本文在对比多种无损检测方法及研究感应式磁声成像的基础上提出了感应式磁声检测的新方法。该方法是在静态磁场下，通过脉冲电流激励被测钢板表面，进而在钢板内部发生电－磁－声的相互转化，最后提取钢板表面的磁声信号。该方法与被测材料无接触，无耦合，可在恶劣环境下进行工作，非常适合钢板的在线检测。
