for the four fluid-film lubrication regimes in equations (4), (9), (14), ana (20), we used these equations to develop a map of the lubrication regimes in the form of dimensionless minimum-film-thickness-parameter contours. These maps are shown in figures 1 to 3 on a log-log grid of the dimensionless vis-cosity and elasticity parameters for ellipticity parameters of 1, 3, and fa, respectively. The fluid-film lubrication produces the lowest amount of wear and can be realized most easily in hard-on-hard tribological couplings. With COC coupling, it is possible to accomplish fluid-film lubrication due to the high level of hardness of ceramics and the very low residual surface roughness that can be . This book offers a systematic treatment of the fundamentals of fluid film lubrication and fluid film bearings. The introduction places fluid film bearings within the broader context of tribology, a subject that encompasses friction, lubrication, and wear. The early chapters provide a thorough discussion of classical tribological theory. The remainder of the book is devoted to more advanced.

Fluid film lubrication occurs when opposing surfaces are completely separated by a lubricant film and no asperities are in contact. The applied load is carried by pressure generated within the fluid, and frictional resistance to motion arises entirely from the shearing of the viscous fluid.
