How do you do corrosion mapping?
Corrosion mapping is a quantitative way to inspect a material where oxidation or erosion has reduced its thickness. Since an ultrasonic path is directly reduced on a corroded part, a conventional UT beam can report one specific thickness at a time while a phased array scan can produce an array of thicknesses.
