Ionic liquids as boundary additives in water-based and PAO lubricants

Friction, 2021
Ionic liquids have been widely discussed as potential lubricants, however, their properties make them also very good potential candidates as lubricant additives (e.g., friction modifiers and anti-wear).

Flow Characteristics of Oil-Carrying by Water in Downward-Inclined and Horizontal Mobile Pipeline

Energies
After transporting oil with a mobile pipeline, it is necessary to empty the oil within the pipeline. A common method is to inject water into the inlet to push the oil out.

Tribological Properties of Biodegradable Universal Tractor Transmission Oil [PDF]

Tribology in Industry, 2016
The annual consumption of lubricants in the world is around 40 million tons out of which less than 40 % are collected and properly processed meaning regeneration, re-refining and controlled incineration while the rest is disposed without control thus ...

The Hydrodynamic Radii of Viscosity Index Improvers for Lubricant Oils

Tribology Online, 2019
Viscosity index improvers are polymeric additives that are commonly used to control the viscometrics of lubricants. Nevertheless, there have been few studies on the molecular size of these additives, which is the origin of their viscosity-increasing ...

The Effect of Addition of Nanoparticles, Especially ZrO2-Based, on Tribological Behavior of Lubricants

Lubricants, 2020
The aim of the paper was to discuss different effects, such as, among others, agglomeration of selected nanoparticles, particularly those from zirconia, on the tribological behavior of lubricants. The explanation of the difference between the concepts of

Understanding the Effect of Resistance Temperature Detector Temperature Controllers on Microstructural Alignment in Magnetic Freeze Casting

Advanced Engineering Materials, EarlyView.
The effect of temperature controllers that are commonly used in freeze‐casting is investigated in this work. Temperature controllers are observed to generate a voltage in the slurry. Microstructural alignment and ultimate compressive strength data show this voltage to interfere with the ability to align the microstructure using magnetic fields ...
