Research on 3D Magnetic dipole model of MFL signal for arbitrary orientation defect and MFL extension technology [PDF]
, 2017 作为目前应用最普遍的铁磁性材料的无损检测(non-destructivetestingmethods，NDT)方法之一，漏磁检测(magneticfluxleakagedetection，MFL)具有易量化、高可靠性、高效、低污染等诸多优势。但是，和其它无损检测方法一样，漏磁检测也具有一定的局限性，主要体现在对裂纹检测（尤其是轴向裂纹）的灵敏度不高，磁化器体积较大且不能区分内外壁缺陷几个方面。为解决这几个问题，本文采用了一系列的漏磁检测扩展技术针对性地提出了解决方案。作为研究着力点以及分析工具 ...
