Development of a Set of Stribeck Curves for Conformal Contacts of Rough Surfaces
TLDR
The Stribeck curve is an overall view of friction variation in the entire range of lubrication, including the hydrodynamic, mixed, and boundary lubrication as mentioned in this paper, and is used to model the friction of a journal-bearing conformal contact system through numerical simulation.Abstract:
The Stribeck curve is an overall view of friction variation in the entire range of lubrication, including the hydrodynamic, mixed, and boundary lubrication This paper presents the results of research on the friction of a journal-bearing conformal contact system in the form of Stribeck curves through numerical simulation The surface roughness of the journal and the bearing and material elasticity and thermoelasticity are included in the modeling, and their influences on the results of Stribeck curves are discussed A three-dimensional Stribeck surface is constructed to illustrate the load effect on friction for the modeled journal-bearing structure Review led by Gary Barberread more

Lubrication mode analysis of articular cartilage using Stribeck surfaces.
TL;DR: Developing an in vitro cartilage on glass test system to measure friction coefficient, mu, and implementing and extending a framework for the determination of cartilage lubrication modes to determine the effects of synovial fluid on mu and lubrication mode transitions were successful.

Simulation of journal bearing friction in severe mixed lubrication – Validation and effect of surface smoothing due to running-in
TL;DR: In this paper, a simulation approach for journal bearings operating from hydrodynamic to mixed lubrication regime where severe metal-metal contact occurs is presented, and the simulation results in the form of Stribeck curves provide a solid base to prove the isothermal elastohydrodynamic simulation approach.

Effect of Surface Pattern on Stribeck Curve
TL;DR: In this article, the effect of surface pattern on frictional characteristics of lubricated contact is studied and an algorithm based on the load sharing concept is developed which assumes that the total transmitted load is carried by the asperities as well as the fluid film.

Direct Formation of Lubricious and Wear-Protective Carbon Films from Phosphorus- and Sulfur-Free Oil-Soluble Additives
Blake Johnson,Hongxing Wu,Hongxing Wu,Michael Desanker,David Pickens,Yip-Wah Chung,Q. Jane Wang +6 more
TL;DR: In this article, a surface-active molecule with a metastable cycloalkane ring was proposed for the formation of carbon tribofilm. The additive consists of a surface active molecule, which dissociates readily during tribological contact to form lubricious carbon films.

The genesis of friction
Nam P. Suh,H.-C. Sin +1 more
TL;DR: In this paper, the genesis of friction is explained in terms of a new theory, which postulates that the frictional force (and thus the friction coefficient μ) is affected by the sliding distance and the environment because of the changing contributions of three components of friction, i.e., deformation of surface asperities, plowing by wear particles and hard as perities, and adhesion of the flat portions of the sliding surface.

Generalized effects in confined fluids: new friction map for boundary lubrication
TL;DR: In this paper, the authors assess the validity of current presentations of friction processes, such as the Stribeck curve, and propose new constitutive relations and a dynamic friction map, including an alternative stribeck type curve representation, which are also formulated in terms of more accessible parameters.
