摘要

本文重点分析了AISI h11型热加工工具钢的摩擦学性能，以及这些性能对热处理参数的影响。研究了磨料在不同接触条件下的耐磨性，以及力学性能与耐磨性的关系。实验结果表明，合理选择奥氏体化温度和回火温度，可以获得刀具硬度、强度和韧性的最佳组合。干滑动接触条件下的摩擦系数和磨料磨损方式在很大程度上与热处理条件无关，更多地取决于接触条件，尤其是载荷。另一方面，硬度和强度是控制热加工工具钢磨料耐磨性的主要力学性能。

DRY-SLIDING WEAR RESISTANCE OF AISI H11-TYPE HOT-WORK TOOL STEEL

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.
