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 ...

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.

The Investigation on Lubrication State of Gears

Tribology Transactions, 1994
A computer program for analyzing the lubrication state of gears was developed, and the lubrication states of two lubricants on two test rigs were investigated. The calculation and tests correlated well. Finally, satisfactory results were achieved when the program was used on an industrial field. Presented at the 48th Annual Meeting in Calgary, Alberta,

Lubrication with materials in the solid state

British Journal of Applied Physics, 1951
Coefficients of friction between flat mild steel surfaces loaded at an average intensity of 40 lb/in2 at relative velocities of 0.01 cm/sec and 0.4 cm/sec were determined using talc, vermiculite, flake graphite, paraffin wax and various metallic soaps as lubricants.

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 ...

On the Magnitude of Cavitation Pressure of Steady-State Lubrication

Tribology Letters, 2013
The value of cavitation pressure plays an important role in the implementation of the mass-conservative algorithm. This is particularly crucial in applications that deal with analysis of surface textures. In this paper, published research on cavitation of journal bearing and surface textures are reviewed, and experiments and simulations of textured ...

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 ...
