摘　　要：探讨了H13模具钢的低温盐浴氮碳钒共渗工艺,并对渗层组织、硬度、渗层中的元素分布以及物相组成等进行了研究。结果表明:低温盐浴氮碳钒共渗工艺明显提高了H13模具钢的显微硬度,并且渗层中的物相有利于提高模具的热疲劳性能和耐磨性,采用该工艺处理H13热作模具,使用寿命有了明显改善。The technological process of die steel H13 was inguired by low temperature salt-bath vanadium-nitrocarburizing, and mierostruetures, hardness, element distribution and phases of the infiltration of samples were investigated. The result shows that the mierohardness is improved, and the phases of infiltration is benefit for improving the thermal fatigue properties and wear resistance. The life of dies which is made of steel H13 treated by the technics is improved obsviously.
