Corrosion Monitoring and Inspection Technologies

There are numerous methods that may be used to monitor or inspect components for corrosion and corrosion related damage. The following section is aimed only at introducing available technologies and their applicability to the various forms of corrosion. Corrosion monitoring involves methodologies to assess the corrosivity of a system which may or may not be continuous (real-time monitoring) and to continuously monitor systems for defect formation. Corrosion inspection is the periodic checking of a system for corrosion and corrosion related defects. Since corrosion fatigue and stress corrosion cracking involves the formation and propagation of cracks, monitoring and inspection techniques to look for surface and subsurface cracks have been included.
