Abstract: Based on the application of zirconia-matrix self-lubricating ceramic composites in sliding parts and rolling contact bearings, the effects of preparation technology, solid lubricants, friction test temperature and sliding against counterparts on zirconia-matrix self-lubricating ceramic composites and the formation mechanism of lubricating film are introduced in this paper. The existing problems with zirconia-matrix self-lubricating ceramic composites and the future development of the materials are briefly described.

Key words: zirconia; self-lubrication; solid lubricant; tribological properties
