Abstract

The study of different kinds of coating of SiFe sheets is reported. Several surface resistance measurements have been carried out with the standard Franklin device. In order to interpret results and to get an accurate characterization of sheet insulation, a physical approach has also been followed using scanning electron microscopy, X-ray analysis, roughness and thickness testers. The correlation between these two ways of investigation has also revealed that the scattering of resistance values reflects the inhomogeneity of the insulating layer caused by the coating itself and by the profile of the iron sheet due to roll prints
