Paper Abstract

Barkhausen noise measurements were used to determine the thickness of several micrometer thick zinc coatings on steel wires. Barkhausen noise is a broadband frequency signal ranging from several KHz to MHz. By comparing the attenuation of the noise through the zinc layer for different frequencies, it is possible to determine the thickness of the Zn coatings. An advantage of the method is that the attenuation of the signal can be calculated if the conductivity of the coating layer is known. Therefore, no calibration procedures are required.
