Abstract
The trbriological properties of FeS solid lubrication composite layer were carried out on the type MS-T4000 friction wear testing machine. Morphology and elements analysis of wear surfaces was carried out on ultra high resolution field emission scanning electron microscope (FESEM) and X-ray photoelectron spectroscopy (XPS). It is shown that the friction process of FeS solid lubrication composite layer can be divided into three stages. The friction coefficient of FeS solid lubrication composite layer is about 0.16 in the first stage, the friction mainly occurred in the surface of FeS solid lubrication. The friction coefficient is about 0.20 to 0.25 and is about 0.40, in the second stage and the third stage, respectively. The wear surface of FeS solid lubrication composite layer was smooth without obvious furrow. On the wear surface, there were mainly granular and flatteners-like FeS films.
