摘要：
A computer model of a weakly magnetic finely dispersed coating is suggested. The magnetic inspection of the thickness of such coatings deposited on nonmagnetic and weakly magnetic bases is substantiated. The effect of the nickel content in the coating on the error of thickness measurement is estimated. It is shown that, at the same average nickel concentration, a nonuniform nickel distribution across the thickness does not affect markedly the informative signal.
