Nondestructive Testing for Corrosion Evaluation of Metal under Coating
Journal of Sensors, Volume 2021, Issue 1, 2021., 2021 The use of steel has grown rapidly over the past decades. However, corrosion under coating detection still presents challenges for nondestructive testing (NDT) techniques. One of such challenges is the lift‐off introduced by complex structures. Inaccessibility due to structure leads corrosion to be undetected, which can lead to catastrophic failure ...

Complexity, Volume 2021, Issue 1, 2021., 2021 One of the most efficient nondestructive methods for pipeline in‐line inspection is magnetic flux leakage (MFL) inspection. Estimating the size of the defect from MFL signal is one of the key problems of MFL inspection. As the inspection signal is usually contaminated by noise, sizing the defect is an ill‐posed inverse problem, especially when sizing ...
