摘要
A non-planar part has a non-planar surface such as an edge, and may contain an anomaly such as a crack. The non-planar part is inspected using an eddy current technique. The method includes providing the non-planar part having the non-planar surface thereon, driving an eddy current probe at two or more frequencies, measuring an eddy current response signal of the non-planar part at each frequency, and performing a multifrequency phase analysis on the eddy current response signals.
