Application of Pulsed Excitation to Estimate the Corrosion Damage of Aluminum Alloys by the Eddy Current Method

Abstract—The possibility of determining the degree of corrosion damages of various types by the eddy current control method using a laid-on probe is considered. A two-frequency method is proposed for separate control of the degree and type of corrosion damages. A method for selecting frequencies for monitoring is described. The developed method of estimating the degree of corrosion damage is experimentally tested.
