Aluminum 2024-T3 samples have been purchased, machined and coated. Electrochemical corrosion testing is in the process of being performed on these samples, using AC impedance measurement, ellipsometry and X-Ray Photoelectron Spectroscopy XPS. Electrochemical impedance measurements are being used to acquire a precise impedance signature which will be used to develop a sensor for detecting corrosion processes on aircraft. The objective of this Phase 1 project is to show that a distinct signature obtained from a corroding aircraft surface can be used to develop a sensor. Data have been collected using AC impedance testing and X-Ray Photoelectron Spectroscopy.
