A magnetic method for testing the thickness of two-sided weakly magnetic coatings by a nonmagnetic base

The general case where the depth of the informative zone is greater than the thickness of a nonmagnetic base having a two-sided weakly magnetic coating is considered. In this case, the informative signal is determined by the thickness of the base and coating on both sides. A technique for separately...

Summary:The general case where the depth of the informative zone is greater than the thickness of a nonmagnetic base having a two-sided weakly magnetic coating is considered. In this case, the informative signal is determined by the thickness of the base and coating on both sides. A technique for separately measuring the coating thickness on either side taking into account the effect of both coatings on the informative signal is proposed as applied to the magnetodynamic method.
