<p>Eddy current testing (ECT) system for the spring steel materials that is able to estimate crack shape was developed. Inspection signal of spring steel material is affected by the permeability distribution about its surface. Then the magnetizer ...
<p>A high-speed and high-sensitive eddy current testing (ECT) system was developed for the inspection of spring steel materials in manufacturing lines. The permeability distribution of the steel materials affects inspection results and the signal-...
<p>Mechanical parts, plants and cross-linkages inspected with MT are typically complex 3D shapes. In the complex 3D shape portion, because a magnetizer often cannot be configured to the inspection portion and the test object cannot be appropriatel...

As magnetic particle testing (MT) detects microcracks using a simplified method, it is used for non-destructive inspection of ferromagnetic materials in various industrial fields. However, MT can provide only a rough distribution shape of a crack;...

Nonuniform permeability distribution in ferromagnetic materials creates noise in eddy current testing (ECT). To overcome this problem, ferromagnetic materials are magnetized and inspected in the magnetic saturation state to reduce noise. In this s...
