A study of the nondestructive evaluation methods and techniques for determining the extent of corrosion on a structure points out the possible drawbacks and the promising aspects of each method and makes improvement suggestions. Methods and techniques discussed are the result of research and experience at NASA, major aerospace companies, equipment suppliers, and universities. The report may be of interest to metal societies, plastic societies, structural firms, and corrosion protection firms. Six types of corrosion are reviewed: general, galvanic, filiform, pitting, intergranular, and stress. Among the techniques studied are the following: direct and remote viewing; radiography; penetrant; eddy current; pH analysis; chemical spot tests, polarized light reflection; and ultrasonic techniques, including compression wave, delta principle, shear wave, and surface wave.
