Abstract:

A feasibility demonstration was conducted at the facilities of Physical Research Instrumentation Company, (RI) in Redmond, Washington. The purpose of the demonstration was to compare the effectiveness of the PRI Model 301-1 magneto-optic imaging (MOI) system with conventional eddy current methods in detecting corrosion in aircraft test panels, previously identified by eddy current scanning. The study indicates that MOI may not be able to detect gradual differences in thinning which is less than 10% of base metal thickness. Also, with MOI, it appears to be more difficult to provide quantitative estimates of residual thickness than is the case with eddy current scanning. On the other hand, MOI visualization of the extent of corrosion is simple and free of the labor intensive point-by-point mapping, which is required by eddy current scanning.
