介绍了电解质气相离子催渗技术 (简称ECA催渗技术 )以及该技术在我厂可倾式滚筒和连续渗碳 (CN共渗 )网带炉上的试验过程及应用。试验表明 ,ECA催渗剂不仅提高渗碳速度 2 5 % ,节约能源 ,而且有效地细化晶粒 ,改善工件碳浓度梯度 ,使产品质量得到明显提高 ,具有非常显著经济效益和广阔的应用前景 The process and application of electrolyte gas phase ion catalysis (referred to as ECA seepage) technology and its application in the tilting drum and continuous carburizing (CN co-permeation) belt furnace of this plant are introduced. The results show that the ECA catalyst can not only increase the carburizing rate by 25%, save energy, but also refine the grains and improve the gradient of the carbon concentration in the workpiece so that the quality of the product can be obviously improved, which has very significant economic benefits and broad application prospect
