Abstract:
1. A method for visualizing effects of corrosion, the method comprising: interrogating a workpiece with radiation; generating a backscatter image of the workpiece based upon radiation backscattered from the workpiece; comparing, with a processor, one or more regions of the backscatter image of the workpiece with each of a plurality of backscatter images of different respective metal loss indicators, each metal loss indicator being a physical representation of a different amount of metal loss, wherein comparing comprises determining which of the plurality of backscatter images of the different respective metal loss indicators match the one or more regions of the backscatter image of the workpiece by having colors or gray scale levels that are identical or within a predefined range of one another; and as a result of the comparing, estimating, with the processor, the metal loss attributable to corrosion of the workpiece.
