摘要

提出了一种低温等离子体电解氮碳共渗结合气淬和三级回火提高R6M5高速工具钢表面硬度和耐磨性的工艺。研究了处理前后高速钢表层的组织和相组成。结果表明：淬火后氮碳共渗形成含氮化物夹杂的高合金马氏体组织，回火后析出细小分散的碳化物，导致淬火后表层硬化至1140 HV，回火后表层硬化至1380 HV。

Increasing the Wear Resistance of High-Speed Steel R6M5 Using Plasma-Electrolytic Nitrocarburizing

A technology is proposed to increase the hardness and wear resistance of the surface of R6M5 high-speed tool steel using low-temperature plasma electrolytic nitrocarburizing in combination with air quenching and three-stage tempering. The structure and phase composition of the surface layers of high-speed steel before and after treatment were studied. It was shown that the formation of a high-alloy martensite structure with nitride inclusions after nitrocarburizing with quenching and the precipitation of finely dispersed carbides during subsequent tempering leads to hardening of the surface layer to 1140 HV after quenching and to 1380 HV after subsequent tempering.
