Lubricity Synergism in Boundary Lubrication
World Tribology Congress III, Volume 1, 2005Dimethyl Ether (DME) has been known as a ultra clean smokeless fuel for diesel engines for over a decade now. A significant challenge is to ensure full lifetime for the diesel engine injection equipment when handling the low boiling point DME as this fuel has very low viscosity and lubricity.

Boundary Lubrication Mechanisms for High-Performance Friction Modifiers.
ACS Applied Materials and Interfaces, 2018We recently reported a new molecular heterocyclic friction modifier (FM) that exhibits excellent friction and wear reduction in the boundary lubrication regime. This paper explores the mechanisms by which friction reduction occurs with heterocyclic alkyl-

Boundary Lubrication by Associative Mucin
Langmuir, 2015Mucus lubricants are widely distributed in living organisms. Such lubricants consist of a gel structure constructed by associative mucin. However, limited tribological studies exist on associative mucin fluids. The present research is the first to investigate the frictional behavior of a typical intact vertebrate mucin (loach skin mucin), which can ...

In this study, the friction properties and wear performances of monolayer and multilayer coating structures operating under hydrodynamic, mixed and boundary lubrications have been evaluated using a ball-on-disc configuration. Results showed that, whereas

Evidence is reviewed for the concept that the body employs essentially the same lubrication system in many sites in the body where tissues slide over each other with such ease. This system consists of fluid adjacent to surfaces coated with an oligolamellar lining of surface-active phospholipid (SAPL) acting as a back-up boundary lubricant wherever the

Boundary lubricating films: formation and lubrication mechanism
Tribology International, 2005Boundary lubricating films are critical in effective lubrication of engine components. Their formation mechanism is not fully understood due to the lack of understanding of how molecular structures of the base oils and the antiwear additives work together.

Wear is a complex subject. Wear studies under lubricated conditions can be classified into two categories: wear mechanisms study of the materials under ‘lubricated’ conditions, and the evaluation of the lubricant chemistry using the same materials.

Boundary Friction and Boundary Lubrication
Scientific Lubrication, 1957Friction arises at the real contact area of two contacting bodies. This area depends on the mechanical properties of the bodies, geometrical configuration, and load. The authors described a new optical method of determining the area of contact, developed in the Laboratory of Friction and Friction Materials of the Academy of Sciences, Russia.

Boundary Lubrication and Boundary Films
1993Despite many years of research, boundary lubrication remains the least well understood regime in the Tribological pantheon. This is in part because it is a broad church, spanning a wide range of quite different phenomena which are, in practical terms, very difficult to disentangle. Also the processes involved in boundary lubrication are very localised,
