Reliable evaluation techniques for localized corrosion damages

Reliable structural integrity assessment of a components is strongly dependent on the reliable evaluation techniques for the damages taking place on the component. Amongst the various causes of deterioration of metals and materials, corrosion is considered as one of the most dangerous culprit in raising doubt on integrity of components. Amongst the various forms of corrosion, localised corrosion is called as the silent killer of the materials. Fortunately during the last few years a number of reliable techniques have been developed who can predict exactly the extent and kinetics of corrosion taking place on a material in contact of corrodents. These techniques also help in understanding the mechanism of corrosion which is used in devising of suitable techniques to combat the corrosion and extend the life of a component. This paper incorporates the methodologies in brief on such techniques.
