ABSTRACT
The purpose of this chapter is to describe the characteristics of graphite fluoride as a solid lubricant. Generally, sliding conditions are divided into three steps: (1) dry friction: sliding without any liquid environment or oil adsorption; (2) boundary lubrication: sliding with absorbed oil film; and (3) hydrodynamic lu brication: sliding with a liquid or gas layer between sliding surfaces. According to a classical model, the coefficient of friction (= frictional force/applied contact load) shows transients depending on the sliding condition, as indicated in Fig. 1.
