Detection of Surface and Subsurface Flaws with Miniature GMR-Based Gradiometer
The eddy-current (EC) testing method is frequently utilized in the nondestructive inspection of conductive materials. To detect the minor and complex-shaped defects on the surface and in the underlying layers of a metallic sample, a miniature eddy ...

Comparison of different types of focusing probes in pulsed eddy current testing
Pulsed eddy current (PEC) testing has attracted widespread attention because of its unique advantages in detecting local defects in insulated pipes. In this paper, rectangular, U-shaped, and semicircular PEC focusing probes are designed, the magnetic ...

Standard flaws for eddy current probe characterization
Calibration procedures for eddy current inspections often involve the use of artifact standards containing manufactured flaws. The manufactured flaw is assumed to be a good approximation of the type of flaw being sought during the inspection. These manufactured flaws are most often produced by electrical discharge machining (EDM), milling, or the ...

Eddy current probes fabricated with cores made of ferrite-loaded silicone rubber RTV are flexible; they can be used to scan components with contours of varying radii. A typical application would be the inspection of rocket nozzles; the radius of curvature changes between the throat and the base, with additional curvature in the axial direction.

Eddy Current Probe Performance Characterization
Single-coil, absolute eddy current probes are used extensively by the Air Force for inspection of aluminum airframe structures. Because of the large variations in probe performance [1], a specification is needed to ensure that probes meet minimum performance criteria.

In the present work, we have identified a transcriptional signature based on the differential expression of six genes (BCL2&MAST4, HSH2D&LAT2, METRN&PITPNM2) that would facilitate the early detection of T‐cell acute lymphoblastic leukemia (T‐ALL) patients prone to a poor treatment response and could be implemented at diagnosis, along with other risk ...

Comparison of defect detection limits in Lorentz force eddy current testing and classical eddy current testing [PDF]
Lorentz force eddy current testing (LET) is a motion-induced eddy current testing method in the framework of nondestructive testing. In this study, we address the question of how this method is classified in comparison with a commercial eddy current ...
