本文介绍了一种新的粒状渗钒剂,具有良好的渗钒效果,可重复使用5～6次。本文中分析了温度、时间以及不同钢种渗钒对渗层深度及组织结构的影响。还进行了耐磨性、脆性及耐蚀性试验,及渗后热处理工艺研究。目前,粒状渗钒剂已在刃口单薄的落料模、成型模及冷镦模上应用,取得了较好的效益。 This article describes a new granular vanadizing agent, with good vanadia effect, can be reused 5 to 6 times. In this paper, the effects of temperature, time and the infiltration of vanadium on the depth and microstructure of the infiltration layer were analyzed. Also carried out wear resistance, brittleness and corrosion resistance test, and heat treatment after infiltration technology. At present, grainy vanadizing agent has been applied to the thin blanking blanking die, forming die and cold heading die, and has achieved good benefits.
