Abstract
Evaluating the specific electrical conductivity of two-layered nonmagnetic objects by the pulsed eddy-current method is considered. Eddy-current transducer signals are investigated using a finite element model. Based on simulation results, depending on the ratio of the parameters of the coating and the base of a test object, two methods are proposed for determining the specific electrical conductivity by integration of magnetic flux. The working capacity of the proposed technique has been confirmed in a laboratory experiment.
