Description
Summary:This paper presents an approach for multifrequency eddy current testing based on special waveform excitation signals. Digital processing of received signals provides data for experimental hodographs of a “sensor – testing sample” system. Hodographs for the testing of samples of aluminum materials with an applied dielectric layer demonstrates the reliability of the proposed approach. The application of principal component analysis improves the identification and differentiation of testing parameters. The obtained results can be used in systems for nondestructive testing of metallic materials and products.
