Abstract
The severe operation conditions of the hot working process lead to premature failure of the hot working tools. 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.

High-temperature sliding wear of metals

TL;DR: In this paper, the authors reviewed the main findings of extensive research programs into the development of wear-protective layers, including a model that accounts closely for the observed effects of temperature on wear rates during like-on-like sliding, and showed that at low temperatures, the layers generally consist of loosely-compacted particles; at higher temperatures, there is an increase in the rates of generation and retention of particles while compaction, sintering and oxidation of the particles in the layers are facilitated.
