Certification of hardened surface layers by magnetic and electromagnetic methods

  • Technical Information
  • Published:
Metal Science and Heat Treatment Aims and scope

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.
