W pracy przedstawiono zjawiska fizyczne przebiegające w procesie tarcia, które mają wpływ na reakcje chemiczne, katalityczne i tribochemiczne. Podano właściwości fizykochemiczne i tribologiczne reprezentatywnych materiałów ceramicznych. Omówiono na przykładach reakcje katalityczne i tribochemiczne zachodzące w czasie tarcia na powierzchniach elementów ceramicznych z udziałem wody, olejów smarowych i niektórych dodatków uszlachetniających.

Chemical interaction with ambient gases and with components of lubricant liquids influence the friction forces and wear rate of ceramics. Physical phenomena occuring in friction affect chemical, tribochemical and catalytic reactions. In the presence of water vapor or hydrocarbon lubricants and lubricating oil additives for example, tribochemical reactions decrease or increase wear, depending on the kind of ceramics. These different types of behaviour can be understood in terms of the surface chemistry of ceramics, which is dominated by charge transfer with ambient gases and components of lubricants through acid-base reactions. Some physicochemical and tribological properties of ceramics are presented. Examples of catalytic and tribochemical reactions in friction, employing water, base oils and some lubricating oil additives for ceramics are discussed.
