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.

Rehabilitation And Repairs Of Corrosion Distressed Structures By Composite Fibre Wrapping And Electrochemical Techniques

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 ha ....etc

ABSTRACT

Corrosion, Stress Corrosion Cracking (SCC) and corrosion fatigue failures of high strength aircraft aluminums are costly and potentially catastrophic material problems affecting the aircraft fleet today. As the service lives of aircraft are extended, the increasing inspection and repair of corrosion in aging aircraft adversely affects fleet readiness, the cost of operation, and personnel safety. Shot peening (SP) is a wid ....etc

Corrosion of reinforcements has been one of the major challenges that the civil engineers have been facing. Corrosion leads to the formation of rust which results in the spalling of concrete which in turn leads to the exposure of rebars to the aggressive environment. This will accelerate the ill effects and ultimately leads to the break down of the structure. Corrosion mainly occurs in areas of aggressive environment such as coastal regions. It is very important that corrosion of reinforcement must be prevented in order to have a durable struct ....etc

corrosion
The process of decay of metal by environmental attack is called corrosion.
The basic reason for this attack is most of the metals (except Pt, Au, Ag) exist in nature in the form of their ores as oxides, chlorides, silicates, carbonates etc.,
Metals have the natural tendency to go back to their combined states, as a result when metal is exposed environmental conditions forms stable compounds of metals, known as corrosion.
The process of corrosion is reverse of metal extraction.
Effects of ....etc
