Advanced Eddy Current Methods For Evaluating Aviation Components
(Національний авіаційний університет, 2024-05) Lysenko, I.; Kuts, Y.; Mirchev, I.
The presentation provides guidelines for conducting eddy current non-destructive testing on components made of Al-Mg-Si alloy, a popular material in the aerospace industry due to its high mechanical properties and good corrosion resistance. Several potential defects may exist in such components, including internal voids or blowholes, cracks, corrosion, and inhomogeneities in the material's structure. Internal voids can occur during manufacturing, reducing mechanical strength and potentially leading to failure. Cracks may form due to stress or mechanical influences and can propagate, causing component failure. Corrosion may develop on the surface when exposed to aggressive environments or high humidity, weakening the components. Inhomogeneities arising during manufacturing or thermal treatments can affect mechanical properties and lead to failures.
