概要

A method of eddy current testing (ECT) data mapping for surface breaking evaluation is studied. The multicoil ECT probe utilized in this paper consists of Trans mit-Receive (TR) type sensors as array elements to obtain the information on crack directions. Switching two directional scans, U- and T- modes, gives two-dimen sional vector mapping as ECT images. The ECT signals of the TR type sensor also give the information on crack directions from their variation displayed on the c omplex number plane. Extracting a complex number component of the signals makes it possible to visualize directions of numerically simulated proximate EDM slits.
