摘要
Cr12MoV钢是国内使用最广泛的高碳高铬莱氏体型冷作模具钢,优良的表面处理工艺是保证其高强度高寿命的前提,本文概述了Cr12MoV钢的渗氮、渗硼、渗钒表面化学热处理工艺,以及不同工艺处理下Cr12MoV钢的微观组织结构和性能的改变,阐述了Cr12MoV钢化学热处理的研究现状及发展趋势。
ABSTRACT:Cr12MoV is the most widely domestically used work die steel, and this ledeburite steel has a high carbon and high chromium in its composition. Generally speaking, the advanced surface treating technology leads to the high strength and high life cycle. In this paper, several surface treating technologies such as nitriding, boriding and vanadinizing are summa-ried, and the structure and property changes of Cr12MoV treated by various program are listed and reviewed. Furthermore, the development tendency of surface treating technologies for Cr12MoV is also evaluated.
