... Abstract Tribology is the science and technology of interacting surfaces in relative motion. This article describes in detail the basic structural, operational, and interaction parameters of a tribosystem. The interaction parameters, which characterize the action of the operational parameters...

..., including lubricated testing, the conditions of the tribosystem should be simulated as closely as possible. For example, if brake rotor surfaces become rusty during long idle periods in a parking lot, then rusty surfaces should be used for brake rotor friction testing to simulate this condition. Absorbed...

Such testing is particularly critical for brakes, clutches, and similar power- and motion-control mechanisms where the friction force must be known and controlled. If the friction characteristics of a system are somehow...

..., the reaction is usually oxidation. Fretting wear occurs in tribosystems such as metal versus plastic, where oxidation of nascent surfaces does not usually occur. Abrasive wear by hard particles occurs when one body, in general, a ceramic-like substance, is much harder than the counterface, such as a ductile...
