洛仑兹力涡流检测是一种新的无损检测技术，可较好地应用于非铁磁运动导体内部缺陷的识别。本文介绍了这种新技术与著名的涡流检测的比较。对这两种方法在等速运动的铝合金试件中的人工亚表面缺陷进行了测量和数值模拟。
Lorentz force eddy current testing is a novel nondestructive testing technique which can be applied preferably to the identification of internal defects in non-ferromagnetic moving conductors. This paper describes the comparison of this new technique with well-known eddy current testing. Measurements and numerical simulations have been done for both techniques for artificial subsurface defects in a test specimen made of Aluminum alloy moving with constant velocity.
