The dominant failure of hot working tools is wear of the tool surfaces induced by the thermal softening phenomenon. Several researchers related to the service life extension technology of hot working tools paid attention to the protective overlay coating technology, so called hardfacing, for preventing premature wear of the hot working tool. This paper reviewed recent research on the application of hardfacing technology to hot working tools. In addition, the key technology and the state-of-the art of the hardfacing technology related to improvement of the wear characteristics of hot working tools were discussed. Finally, future research issues of the hardfacing technology to enhance the service life and wear characteristics of the hot working tools were described.
