摘要

采用75%KSCN+25%NaSCN+0.9%K

Fe(CN)

+0.1%K

Fe(CN)

+2.5%NH

SCN的盐浴

45钢为正极

高铬不锈钢为负极

190℃±5℃

1 V电压

20 min低温电解表面渗硫方法

在45钢表面形成10 μm FeS渗层

Abstract

The 10 μm FeS sulphurizing layer forms on surface of 0.45 C steel by low temperature electrolytic sulphurizing process in salt bath of 75% KSCN +25% NaSCN + 0.9% K

Fe( CN)

+0.1% K

Fe( CN)

+ 2.5% NH

SCN with positive electrode 0.45C steel and negative electrode high chromium stainless steel

1 volt at 190 ℃ ±5 ℃ for 20 min

and its friction and wear behavior is studied by M-2000 friction and wear test machine

optical microscope

scanning electron microscope and X-ray diffractometer. Results show that better quality FeS sulphurizing layer surface of 0.45 C steel could be get by low-temperature electrolytic sulphurizing process and the FeS layer can obviously reduce the friction and wear of 0. 5C steel; in condition of dry friction the friction factor o

f sulphurizing surface is 60% of that of non-sulphurizing surface and in condition of oil lubrication the friction factor of sulphurizing surface is 70% of that of non-sulphurizing surface; and in definite load range with increasing the load the reducing friction and wear effect of FeS layer increases.
