ABSTRACT

Detection of corrosion damage in aircraft wing skin structures is an ongoing NDT challenge. Ultrasonic methods are known and well-accepted techniques, which are relatively simple to carry out in terms of setup, probes and instrumentation and operator training. However, with conventional inspection from the top surface using a transducer at normal incidence (0o to the normal to the surface) producing a visual picture in the form of a C-scan, it is very tie consuming to point-by-point inspects large aircraft wing skin areas. I ....etc

Ultrasonic Techniques for hidden corrosion detection
Introduction
Corrosion is one of the serious problem affecting airforce and other aviation industries. It affects the aircraft on its wings, surface, between joints and fasteners. The presences of corrosion underneath the paints of surface and between joints are not easy to be detected. The unnoticed presence of corrosion may cause the aircraft to crash leading to human and money loses. To detect the corrosion present on the metal surface, various method ....etc

Deterioration of reinforced concrete structures due to corrosion of steel is a cause of global concern. The losses due to corrosion every year run into millions of rupees and any solution to this universal problem of corrosion has a direct bearing economy of the country. It is estimated that about 30-40 percent of steel produced each year is used to replace corroded material.
In recent years, the construction industry has seen an increased demand to reinstate, rejuvenate, strengthen and upgrade existing concrete structures. This may be attrib ....etc
