The possibilities of certification of hardened surface layers by measurement of coercive force, eddy current inspection and analysis of the field dependence of differential magnetic permeability μ d (H) are considered. The advantages of analysis of the pattern of peaks on the μ d (H) dependence for estimating the state of surface-hardened steels subjected to subsequent force loading are shown.
