Evaluation of Coating Thickness Using Lift-Off Insensitivity of Eddy Current Sensor
Defect detection in ferromagnetic substrates is often hampered by nonmagnetic coating thickness variation when using conventional eddy current testing technique. The lift-off distance between the sample and the sensor is one of the main obstacles for the thickness measurement of nonmagnetic coatings...
