High frequency signal for corroded
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, … Ver mais Nondestructive testing (NDT) refers to the implementation of the defect detection of material, which at the same time does not affect the material’s future performance. Corrosion is the … Ver mais Unfortunately, metals are susceptible to corrosion. The occurrence of reactions among the metal surface, oxygen and water will result in the loss of electrons and the transformation of metal atoms into metal ions. Examples … Ver mais Nine NDT techniques have been discussed. A comparison of these technologies is provided in Table 1, giving an overview of each method and identifying the advantages and limitations of current techniques. … Ver mais Several NDT techniques have been applied for corrosion detection, and each has certain advantages and disadvantages.
