Abstract

The feasibility of using magnetic Barkhausen emission (MBE) measurement for the evaluation of wear-induced material loss in case-hardened steel is examined in this paper. MBE measurements were carried out on two case hardened carburized steel disks. The MBE signals from the carburized material were significantly different from the base metal. On both disks it was observed that the MBE level increased as material was removed and the remaining case depth decreased. One of these disks had been polished to remove most of the grinding stress, the other had not. A difference was noticed between the results on the two disks which was attributed to the effect of residual stress
