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.

On Lubrication States after a Running-In Process in Aqueous Lubrication

Langmuir, 2019
Recently, many studies have reported the ultralow friction coefficient of sliding friction between rigid solid surfaces in aqueous lubrication. A running-in process that goes through high-friction and friction-decreasing regions to a stable ultralow friction region is often required. However, the role of the friction-decreasing region is often ascribed

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 ...

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.

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 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 ...

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 ...
