Abstract : Various methods have been proposed for measuring case depth in case hardened steels. Each mehtod as described in past literature is restricted in practical application due to problems in area localization, geometry, sensitivity, compositional changes due to carbon and/or nitrogen gradients formed during the hardening process.
