An Analysis of the Process of Applying Technical Lubricating Coatings

Applied Sciences, 2023
The results of research on the process of applying lubricating coatings are presented in this work. For this purpose, plastic greases were used, in which the base oil is perfluoropolyether (PFPE) and the thickener is poly(tetrafluoroethylene) (PTFE). Due

Grease Aging Effects on Film Formation under Fully-Flooded and Starved Lubrication

Lubricants, 2015
Several film thickness measurements were performed with three fresh and aged lubricating greases, their base and bled oils under a wide range of operating conditions using a ball-on-disc test rig with optical interferometry.

Influence of Carbon Nanoparticles on Electrically Induced Wear of Grease‐Lubricated Steels

Advanced Materials Interfaces, EarlyView.
When an electric current enters a pair of rubbing surfaces, enormous damage takes place. In this research, how such damage occurs in the presence of protective grease and the mitigation with added carbon nanoparticles, were investigated. It was discovered that those particles regulate transport and interfacial electrical stability of the grease ...

3D Printed Omniphobic Slippery Liquid Infused Porous Surfaces for Low Surface Tension Repellency

Advanced Materials Technologies, EarlyView.
A 3D printing strategy fabricates omniphobic slippery liquid‐infused porous structures with lubricant reservoirs and interconnected microchannels. A post‐printing surface treatment modifies the porous surface to ensure compatibility with the infused fluorinated lubricant.

Influence of various oiling compositions used in conservation on the physical and mechanical parameters of binding leather [PDF]

E3S Web of Conferences, 2020
Protection of leather bindings from the influence of an unfavorable environment is one of the most important tasks of conservation. One way in which this is accomplished is by treating the leather part of an object with an oil or lubricating dressing ...
