Title:
位相分析による多周波渦電流を使用した非平面状部品の検査
Document Type and Number:
Japanese Patent JP5155566
Kind Code:
B2
Abstract:
A non-planar part (32) has a non-planar surface (35) such as an edge, and may contain an anomaly such as a crack (40). The non-planar part (32) is inspected using an eddy current technique. The method includes providing the non-planar part (32) having the non-planar surface (35) thereon, driving an eddy current probe (22) at two or more frequencies, measuring an eddy current response signal of the non-planar part (32) at each frequency, and performing a multifrequency phase analysis on the eddy current response signals.
