Ceramics have been proposed for a wide variety of applications that take advantage of low weight and hardness at high temperatures. But despite their stability against chemical attack and corrosion over a wide temperature range, ceramics are chemically quite active when subjected to friction and wear. The interaction of friction and chemistry is called tribochemistry; tribochemical reactions influence the friction coefficient as well as wear mechanisms and wear rates. The authors describe how water and hydrocarbons alter the tribological characteristics of oxide ceramics and covalently bonded ceramics. Understanding these characteristics is crucial to finding the appropriate ceramic for a particular application.
