Aluminum alloys are used extensively in aircraft due to their high strength-to-weight ratio. A main drawback is that their microstructure is sensitive to corrosion, which generates pits for example. Although corrosion damage can be detected by non-destructive testing methods, such methods are limited in their ability to identify corrosion initiation and the mechanism behind the defect. As a result, corrective actions are only undertaken when corrosion becomes evident (cracks or loss of thickness).

Chapo: 
Design, develop and validate the application of ultrasonic corrosion sensors (UCS), combining passive (Acoustic Emission) and active (Pulse Echo Ultrasonic Testing) types, for corrosion monitoring, enabling them for real time detection of early stages of localized corrosion as well as for monitoring the progress of damages with time.
