Popis:	Calcium cyclohexoxylborate (CaCHOB) was prepared, and its antiwear and friction-reducing properties were investigated on a four-ball tester and an HQ-1 friction machine. X-ray photo-electron spectroscopy (XPS) and scanning electron microscopy (SEM) were used to determine the chemical states of the tribo-logical species on the rubbing surfaces. The results indicate that CaCHOB demonstrates good tribological performance. XPS and SEM analyses showed that surface films containing CaO and B2O3 were formed. These films were deposited on the rubbing surface and improved the lubricating state of the friction surface.
