High Pressure Rheology of Lubricants (Part 5)

open access: yesTribology Online, 2022
The Walther equation is often used for the viscosity temperature characteristics of lubricants. However, it was found that it cannot be applied to high pressure viscosity.

Advanced Control of Frictional Properties on Paper Clutch Materials by a Combination of Friction Modifiers

open access: yesTribology Online, 2017
This study proposes a novel approach for controlling frictional performances at paper clutch systems by a combination of organic friction modifiers (OFMs). The OFMs are commonly used for modifying the frictional properties at the paper clutch.

Measurement of Oil Film Thickness Distribution between a Slipper and Swash Plate in Swash-Plate-Type Axial Piston Pumps

open access: yesTribology Online, 2022
In this study, slipper/swash plate sliding test rigs were developed to measure oil film thickness distribution. For this purpose, fluorescence measurement was performed with a sapphire glass swash plate and a light emitting diode as the light source. The

The Influences on Field-induced Chains by non-magnetic Microstructures inside the Magnetorheological Fluids Based on PTFE-oil Organogel

open access: yesApplied Rheology, 2018
Polytetrafluoroethylene (PTFE) micropowders were used to prepare PTFE-oil organogel. Carbonyl iron particles were dispersed in this organogel to fabricate magnetorheological fluids.

Investigating the Effect of Engine Lubricant Viscosity on Engine Friction and Fuel Economy of a Diesel Engine [PDF]

open access: yes
Fuel economy is affected, both by fuel and engine lubricant quality. Engine lubricant quality plays a vital role in reduction of fuel consumption by effective reduction of friction between the contact surfaces of engine parts (piston ring assembly ...

Joint Lubrication with Artificial Lubricants [PDF]

open access: yesArthritis & Rheumatism, 1971
AbstractThe joint lubricating properties, in vitro, in bovine metatarsal‐phalangeal joints, of silicone fluid, methyl cellulose and polyvinyl‐pyrrolidone were compared to buffer, serum and synovial fluid. As had been previously reported, synovial fluid was almost twice as good as serum and buffer, which are equivalent in their joint lubricating ...

Lubrication-Enhanced Mechanisms of Bentonite Grease Using 2D MoS2 with Narrow Lateral Size and Thickness Distributions

open access: yesLubricants
2D MoS2 with narrow lateral size and thickness distributions was introduced to promote the anti-friction and anti-wear properties of the bentonite grease (BG) in a state of boundary lubrication.
