柴油机缸套经离子渗硫后在提高其工作性能方面的试验研究

Experimental Investigation on Improved Performance of Ion-Sulphurized Diesel Engine Cylinder Liner

本文推荐一种新的离子渗硫工艺,并对其在处理柴油机缸套上的具体应用进行分析讨论,通过一系列样块、台架和实船的深入试验,证实了该工艺在提高柴油机性能上具有十分明显的效果。为今后生产节能、耐磨、抗拉缸的缸套提供了数据。同时亦为离子硫氮共渗工艺在工模具上的应用,展现了广阔的前途。

A new processing method of ion-sulphurizing is proposed,and its trial applica- tion in diesel engine cylinder liners is analyzed and discussed.Extensive experiments of sample survey,stand test and sea trial have proved that the method is remarkably effective on engine performance,have provided valuable information for on-coming production of energy-saving,wear-resistance and anti-scuffing cylinder liners and,meantime,have sho- wn a Bright prospect for the appllcation of a combined treatment of ion-sulphurizing and ion-nitriding technology to tools and dies.
