    Abstract:

    AISI H13 is an excellent hot work tool steel commonly used for manufacturing dies. These dies are subjected to working conditions with continuous cyclic thermo-mechanical loading, which results into surface failure of dies. So in order to enhance the service life of the die, surface hardening by electron beam is proposed. In this paper, effect of electron beam scanning speed on the hardening case depth of an AISI H13 sample was studied. Microstructure of EB hardened layer has been characterized by optical microscope. The tribological performance of hardening was investigated by pin on disk wear testing. It is found that effective case depth increases with decrease in the scanning speed.
