Magnetic fluids in sealing and lubrication – a state of the art review

Journal of Synthetic Lubrication, 1993
AbstractThe paper is a review of the properties and functions of magnetic fluids and their potential use in tribological applications, such as seals and bearings. They offer new possibilities for achieving low friction, low wear, and no leak‐ age.Magnetic fluids or ferrofluids consist of magnetic particles suspended in a carrier fluid and a coating on ...

The state of the art in cold forging lubrication

Journal of Materials Processing Technology, 1994
Abstract The manufacture of components in steel, aluminium and copper alloys by cold forging production has increased ever since the 1950's. Typical processes are forward rod extrusion and backward can extrusion, upsetting, ironing, tube extrusion and radial extrusion.

The role of water lubrication in critical state fault slip

Engineering Geology, 2020
Abstract The conventional driving mechanisms including elevating the pore pressure or far-reaching poroelastic effects, may not necessarily explain the injection-triggered seismicity that can be up to 35–90 km far away from injection wells. In this experimental study, we examined the mechanism of water lubrication for the triggered seismicity where ...

LUBRICATION OF TITANIUM 'STATE OF THE ART'

1967
Abstract : The advantages of using titanium in marine machinery are outlined, and the difficulty in lubricating machinery constructed of titanium is reviewed. A number of suggestions are given for possible research which might lead to the successful lubrication of titanium machinery components in a marine environment.

The state of art on lubrication methods in space environment

Physica Scripta
Abstract Space tribology is a very big aspect of space exploration, despite of this fact, there is a dearth of coherent and concise literature available in the field of space tribology. It becomes difficult to understand the tribological behaviour of mating bodies under the extreme environmental circumstances in space due to their ...

Impact of Solid-State Properties on Lubrication Efficacy of Magnesium Stearate

Pharmaceutical Development and Technology, 2005
The advent of high-speed tableting and slug capsule-filling machines has ushered in an increasingly important role for the lubricants to enact during manufacturing of dosage forms. Although lubricants help in processing, they can also adversely affect the flow properties and dissolution profile of the drug.

Intelligent method for monitoring the state of lubricating oil

Journal of Friction and Wear, 2016
Mathematical decision-making methods for estimating the state of lubricating oil have been analyzed. It has been demonstrated that the most promising direction for solving problems of determining the performance of oil taking into account the existing uncertainty, ambiguity, incompleteness, and fuzziness of information on the object is the application ...

The present state of lubrication and its relation to rheology

Tribology, 1968
In thick-film lubrication, Reynolds’ equation is generally satisfactory. However, the assumptions made in deriving this equation cannot be justified for non-Newtonian, viscoelastic liquids. It is concluded that no satisfactory mathematical treatment is yet available for calculating the load-carrying capacity of such liquids.

State of Art on Minimum Quantity Lubrication in Grinding Process

Materials Today: Proceedings, 2018
Abstract Most of the machining process use cutting fluids for better cooling and lubrication, which ensures good machinability at low specific energy consumption. However, the conventional cutting fluids pose serious health hazards to operators along with environmental pollution.

Research on thin film lubrication: state of the art

Tribology International, 2005
Thin film lubrication (TFL) has been well studied as a new lubrication regime since 1990s. TFL is a transition lubrication regime between elastohydrodynamic lubrication (EHL) and boundary lubrication (BL), which has specific lubrication features. Present paper summarizes the advancements of researches on TFL, which involves the origin of the TFL ...
