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-p ....etc

Abstract
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 methods and tests are used. These tests conducted should be such that it does not destroy or disassem ....etc

1. CONTROL OF CORROSION OF UNDERWATER PILES Presented by: Avinash Shaw Roll no. 11/CE/45 Department of Civil Engineering NIT Durgapur
2. Introduction Corrosion is the destruction of metals and alloys by the chemical reaction with the environment. Generally many traditional metal parts are used with lighter polymeric components but these are impervious to electrochemical corrosion so even with the proper selection of base metals, there is no absolute way to eliminate corrosion.
3. On steel piling in seawater, the more chemically active surface ....etc
