Abstract:

Electrochemical corrosion testing using AC Impedance measurements, ellipsometry and X-Ray Photoelectron Spectroscopy XPS is progressing according to the Plan of Action and Milestones POAM submitted in July, 1994. The development of the corrosion sensor is on schedule and the feasibility study shows that the proposal to build the sensor is technically sound. A detailed report dated August 15, 1994 was presented to the Program Manager explaining the theory of the AC Impedance, ellipsometry and XPS. The report also explained what the physical concept of the corrosion monitor is, and how it will respond to the various stages of corrosion. The preliminary data presented in the report showed the signature of the initial stages of corroding aircraft structures
