Mixed lubrication — an overview

Lubrication Science, 1997
AbstractThe regime known as ‘mixed’ lubrication lies between those of hydrodynamic and elastohydrodynamic. This paper reviews work on this subject, in order to recognise the key areas of progress, and of ignorance. Film thickness and surface roughness are discussed, to conclude that below certain values of λ, there are limitations to earlier models ...

A Model for Mixed Lubrication

A S L E Transactions, 1975
This paper presents a model for mixed lubrication. The surface asperities are represented by short plasto-elastic cylinders with spherical tops. The heights of these cylinders are assumed to have a Gaussian distribution. By combining the solution of the Reynolds equation and the solution from boundary lubrication theory or the microelastohydrodynamic ...

Basics of mixed lubrication

Lubrication Science, 2003
AbstractThis paper reviews recent research in mixed lubrication, focusing on the current understanding of lubricant entrainment, and thus film thickness, and of friction in thin‐film, rough‐surface lubricated contacts. By combining research using optical interferometry on the experimental side and numerical modelling on the theoretical side, we now ...

Tribological Behavior of Aqueous Copolymer Lubricant in Mixed Lubrication Regime

ACS Applied Materials & Interfaces, 2016
Although a number of experiments have been attempted to investigate the lubrication of aqueous copolymer lubricant, which is applied widely in metalworking operations, a comprehensive theoretical investigation at atomistic level is still lacking. This study addresses the influence of loading pressure and copolymer concentration on the structural ...

Enhanced Lubricity in Mixed Alkanethiol Monolayers

The Journal of Physical Chemistry B, 2005
The frictional properties of two-component mixed alkanethiol monolayers were investigated with frictional force microscopy. With large chain length differences, the two types of molecules segregated into large islands and reveal similar frictional properties as those of single-component monolayers.

Friction Reduction in Mixed Lubrication

Tribology Letters, 2007
Minimization of frictional losses in the drivetrain of heavy-duty vehicles is important from both consumer satisfaction and environmental perspectives. Approaches to friction reduction in these components can be evaluated using simulation-based investigations.

Mixed Lubrication and Lubricated Wear

1993
This review attempts to update our current analytical understanding of the macro-scale lubrication variables such as the average film thickness, lubricant and contact pressures, shear stress, and surface temperature, as well as the micro-scale random variables induced by the randomly distributed asperity contacts.
