摘要
By studying the oxidation behavior of CeF3 in air, a CeF3 compact was prepared on a substrate and the structure is characterized in the paper. Effects of temperature, load and velocity on the sliding friction behavior of the compact were studied on a pin-on-disk tribometer. Findings indicated that the CeF3 compact provided low friction in sliding against Hastelloy C between 400 degrees C and 700 degrees C at high velocity and low load. Analysis results suggested that preferential orientation of plane (002) and the oxidation of CeF3 are the two factors that affect the friction-reducing property of CeF3. Furthermore, the transfer film provided by CeF3 compact provided Hastelloy C with minimized wear rate over the evaluated temperatures. All these suggested that CeF3 can be used as solid lubricant for use from 400 degrees C to 700 degrees C. (C) 1997 Elsevier Science S.A.
