Abstract
This study focused on analyzing the tribological properties of AISI H11-type hot-work tool steel and how these properties depend on the heat-treatment parameters. The investigation focuses on the abrasive wear resistance under different contact conditions and correlations between the mechanical properties and the wear resistance. The results of the experiments show the importance of proper austenitizing- and tempering-temperature selection, thus providing the optimal combination of tool hardness, strength, and toughness. The coefficient of friction under dry-sliding-contact conditions and abrasive wear mode was found to be largely independent of the heat-treatment conditions and more determined by the contact conditions, especially the load. On the other hand, hardness and strength are the dominant mechanical properties controlling the abrasive wear resistance of the hot-work tool steel.
