Corrosion under insulations is described as localized corrosion that forms because of
moisture penetration through the insulation materials or due to contaminants' presence …

Lift-off variation causes errors in eddy current measurement of nonmagnetic plates as well
as magnetic plates. For nonmagnetic plates, previous work has been carried out to address …

In industries, the thickness measurement of non-ferromagnetic coatings on a ferromagnetic
substrate is a difficult problem. In this paper, we proposed a simple but liftoff insensitive …

The detection of lift-off variation presents a significant challenge in many eddy current testing
(ECT) applications, where it is often considered an undesirable signal. To address this …

Physics-based high-fidelity pitting corrosion simulation models have successfully predicted
the evolution of corrosion pit morphology for given mechanical and environmental …

In eddy current testing, lift-off variations between sensor and sample plate affect sensor
inductance and consequently inferred thickness. In this paper, a novel combined inductive …

It is critical for maintaining the safe operation of turbine blades to inspect the potential
structural damages promptly. However, the industry still lacks efficient tools for inspection of …

In the field of pulsed eddy current (PEC) testing, the lift-off effect can mix up the signal
features used for surface hardness classification. In order to improve the accuracy of …

This article proposed a method to simultaneously estimate the permeability, conductivity,
thickness, and lift-off of metallic plates using sweep frequency eddy current measurement …

A new active thermography scheme is here introduced, referred as”'Multi-Frequency
Thermography”', which uses an optimized multi-tone signal for simultaneously implementing …
